The present invention generally relates to securing webpages, and more particularly, to preventing unauthorized users from accessing webpages via Uniform Resource Locator (URL) guessing/network sniffing.
Webpages and web applications may be at risk when underlying pages are accessible by unauthorized users. For example, a web application may provide access to confidential webpages or content intended to be accessible only by authorized users via privileged credentials (e.g., user ID and password of an authorized user). In some situations, these confidential webpages can be accessed using non-privileged credentials or via a session associated with non-privileged credentials. For example, URLs for webpages having confidential content may be guessed, sniffed over a network, obtained via screen shots, or obtained via other documentation.
As an example, a user may use their private credentials to access a root page that contains a URL to another webpage containing private employee information. URL guessing may reveal that changing a single parameter in the URL with a known identifier (e.g., an employee serial number), would direct the user to private information about other employees. This type of exposure could result in a data privacy violation.
In another example, a user of a popular fantasy sports web site may discover that by supplying a direct URL of the third page in a three page team transaction sequence, with substitution of a known ID in the URL, the user could see the hidden team of any other user they desired prior to match day when teams are locked and revealed. This exposure could lead to an unfair advantage for users with this knowledge, loss of reputation for the site operator, and potentially loss of revenue for the site operator. The consequences are far more severe when this type of exposure is present in banking, investment, e-commerce, health, and other highly sensitive sites. Current web vulnerability scan applications lack a mechanism to detect such exposure. Therefore, a solution is needed to detect webpage or web application exposure and alert webpage operators.
In an aspect of the invention, a computer-implemented method includes: generating, by a computing device, a first list of uniform resource locators (URLs) available on a root page when accessing the root page using privileged credentials; accessing, by the computing device using the privileged credentials, respective webpages mapped to each URL in the first list of URLs; storing, by the computing device, one or more first URL outputs, wherein each of the one or more first URL outputs includes content of the respective webpages accessed using the privileged credentials; generating, by the computing device, a second list of URLs available on the root page when accessing the root page using non-privileged credentials; generating, by the computing device, a third list of URLs based on the first list of URLs and the second list of URLs, wherein the third list of URLs includes URLs included in the first list of URLs and not included in the second list of URLs; accessing, by the computing device using the non-privileged credentials, a webpage mapped to a particular URL in the third list of URLs; storing, by the computing device, a second URL output including the content of the webpage mapped to a particular URL in the third list of URLs when the particular URL is accessed using the non-privileged credentials; determining, by the computing device, that the second URL output matches a particular first URL output, of the one or more first URL outputs, associated with the particular URL; and outputting, by the computing device, an alert identifying that the webpage, mapped to the particular URL, is accessible by an unauthorized user based on determining that the second URL output matches the particular first URL output.
In embodiments, generating the third list of URLs list includes generating the third list of URLs by comparing the URLs in first list of URLs with the URLs in the second list of URLs and eliminating the URLs in the first list of URLs that are in the second list of URLs. In embodiments, the alert includes a report identifying a plurality of webpages accessible by unauthorized users. In embodiments, accessing the root page with the privileged credentials or the non-privileged credentials includes submitting the privileged credentials or non-privileged credentials in a form on a login page associated with the root page.
In an aspect of the invention, there is computer program comprising a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computing device to cause the computing device to: receive a list of privileged uniform resource locators (URLs); access a webpage mapped to a particular URL in the list of privileged URLs using privileged credentials; store a first URL output including the content of the webpage accessed using the privileged credentials; access a webpage mapped to the particular URL in the list of privileged URLs using non-privileged credentials; store a second URL output including the content of the webpage accessed using the non-privileged credentials; determine that the second URL output matches the first URL output; and output an alert identifying that the webpage, mapped to the particular URL, is accessible by an unauthorized user based on determining that the second URL output matches the first URL output.
In embodiments, the URLs in the list of privileged URLs are mapped to webpages having confidential content associated with an authorized user. In embodiments, the program instructions cause the computing device to compare the first URL output with the second URL output.
In an aspect of the invention, a system includes: a CPU, a computer readable memory and a computer readable storage medium associated with a computing device; program instructions to access a root page associated with a particular application or website using privileged credentials; program instructions to generate a first list of uniform resource locators (URLs) available on the root page when accessing the root page using the privileged credentials; program instructions to access the root page using non-privileged credentials; program instructions to generate a second list of URLs available on the root page when accessing the root page using the non-privileged credentials; program instructions to generate a third list of URLs based on the first list of URLs and the second list of URLs, wherein the third list of URLs includes URLs included in the first list of URLs and not included in the second list of URLs; program instructions to access a webpage mapped to a particular URL in the third list of URLs using the privileged credentials; program instructions to store a first URL output including the content of the webpage accessed using the privileged credentials; program instructions to access a webpage mapped to the particular URL in the third list of URLs using the non-privileged credentials; program instructions to store a second URL output including the content of the webpage accessed using the non-privileged credentials; determine that the second URL output matches a first URL output associated with the particular URL; and program instructions to output an alert identifying that the webpage, mapped to the particular URL, is accessible by an unauthorized user based on determining that the second URL output matches a first URL output associated with the particular URL. The program instructions are stored on the computer readable storage medium for execution by the CPU via the computer readable memory.
In embodiments, the URLs in the third list of URLs are mapped to webpages having confidential content associated with an authorized user. In embodiments, the privileged credentials are different than the non-privileged credentials.
In an aspect of the invention, a computer-implemented method includes: storing, by a computing device, a first URL output including content of a webpage when a URL of the webpage is accessed using privileged credentials; storing, by a computing device, a second URL output including content of the webpage when the URL is accessed using non-privileged credentials; determining, by the computing device, that the second URL output matches the first URL output; and outputting, by the computing device, an alert identifying that a webpage, mapped to the URL, is accessible by an unauthorized user based on determining that the second URL output matches a first URL output.
The present invention is described in the detailed description which follows, in reference to the noted plurality of drawings by way of non-limiting examples of exemplary embodiments of the present invention.
The present invention generally relates to securing webpages, and more particularly, to preventing unauthorized users from accessing webpages via Uniform Resource Locator (URL) guessing/network sniffing. As described herein, an application server hosts or implements a web-based application or website. The application server provides access to the web-based application or website via user credentials. The application server may present different root pages to different users based on the received user credentials. Different root pages associated with different users may present URLs to different pages based on the pages that different users are permitted to access. URLs mapped to confidential pages can sometimes be determined via guessing and/or network sniffing techniques.
Aspects of the present invention may include a system, method, and program that crawl through a root page hosted by an application server to determine whether unauthorized users are able to access URLs presented on the root page that are intended to be accessible only by authorized users (e.g., if an unauthorized user attempts to access a URL by entering the URL in a web browser). Advantageously, URLs that are accessible by unauthorized users are identified so that security measures can be put in place to prevent these URLs from being accessed using non-privileged credentials. For example, in embodiments, site operators may implement additional firewalls, security checks, redirect mechanisms, or other techniques to prevent confidential webpages from being accessed by unauthorized users.
In embodiments, the present invention may include an application security server to access a root page associated with a particular application or website (e.g., hosted by an application server) using privileged credentials (e.g., by submitting forms that include the privileged credentials). The application security server may be configured to produce a first list of URLs presented within the root page (e.g., a list of URLs intended to be accessible to the user associated with the privileged credentials). The application security server may then “crawl” or access each of the URLs using the privileged credentials and store images of the pages access via the URLs. The application security server may then access the root page associated with the same application or website using non-privileged credentials (e.g., guest credentials, credentials of a different user, etc.), and produce a second list of URLs presented within the root page accessed by the non-privileged credentials (e.g., a list of URLs permitted to be accessible by the user of the non-privileged credentials). In embodiments, the application security server compares the two lists of URLs and generates a list of “privileged” URLs (e.g., URLs that are in the first list, but not in the second list). The list of privileged URLs identifies those URLs that should not be accessible to unauthorized users (e.g., users that attempt to access the URLs using a non-privileged ID).
In embodiments, the list of privileged URLs is processed by accessing the privileged URLs using a non-privileged ID. For example, the application security server may establish a non-privileged session using non-privileged credentials, and request webpages via the non-privileged session using the list of privileged URLs. Images of the webpages accessed using the non-privileged credentials (e.g., referred to as non-privileged URL outputs) may be stored and compared with the images of the pages accessed using the privileged credentials (e.g., referred to as privileged URL outputs).
In implementations, for a particular URL in the privileged URL list, if the non-privileged URL output matches the privileged URL output, a determination is made that the particular URL is accessible using non-privileged credentials (e.g., via a non-privileged session). The determination of a successful launch of a URL using non-privileged credentials may further be based on querying the resulting page for error messages, applying textual pattern matching checks and page size comparison to determine if the webpage loaded successfully. In the event that a URL is accessible from non-privileged credentials, an alert may be generated and provided to a site operator that hosts the exposed webpage. Advantageously, URLs that are accessible using non-privileged credentials are identified so that security measures can be put in place to prevent these URLs from being accessed using non-privileged credentials. For example, in embodiments, site operators may implement additional firewalls, security checks, redirect mechanisms, or other techniques to prevent confidential webpages from being accessed using non-privileged credentials.
In embodiments, multiple pages from a given root page may be bundled together and provided to a site administrator as a security alert. The above processes may be performed on a schedule, upon web page addition or modification, or on demand to test for web site vulnerabilities. In aspects, the URL lists from privileged and non-privileged root pages may be generated in parallel to minimize noise due to time changes. When executed as part of the development process, the systems and/or methods, described herein, have the capability of crawling through other code from the same development environment, as code exposures in one set of web pages from a development team would increase the possibility of similar exposure in other code from the same team.
In another embodiment, the process may be performed in real-time to detect unauthorized access attempts, even if unsuccessful, in which case security alerts may be sent to a security team for further analysis or the user may be given a warning or other action. In this scenario, potential hackers could be identified when a request for a webpage using a URL in the privileged URL list returns an error or message denying access.
Aspects of the present invention solve the technical problem of determining whether an unauthorized user is able to access confidential content via a URL intended to be accessible only by authorized users. For example, aspects of the present invention provide a technical solution to this problem by storing outputs of webpage requests made using privileged URLs and privileged credentials, storing outputs of webpage requests made using privileged URLs and non-privileged credentials, and comparing the outputs. Further, aspects of the present invention provide a technical solution to improving webpage and web application security by outputting alerts to web application and site administrators identifying security exposures (e.g., private webpages that are accessible to unauthorized users via URLs mapped to the private webpages).
The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.
The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing.

A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.

In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.
As shown in
Bus 18 represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus.
Computer system/server 12 typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system/server 12, and it includes both volatile and non-volatile media, removable and non-removable media.
System memory 28 can include computer system readable media in the form of volatile memory, such as random access memory (RAM) 30 and/or cache memory 32. Computer system/server 12 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system 34 can be provided for reading from and writing to a nonremovable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus 18 by one or more data media interfaces. As will be further depicted and described below, memory 28 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention.

Such communication can occur via Input/Output (I/O) interfaces 22. Still yet, computer system/server 12 can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 20. As depicted, network adapter 20 communicates with the other components of computer system/server 12 via bus 18. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system/server 12. Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.
The application security server 210 may request (at step 2.5) a root page using “non-privileged” credentials (e.g., a different set of credentials associated with a different user or a guest user). For example, the application security server 210 may enter the non-privileged credentials at login screen, or select a link for a guest user to access the root page. The application server 220 may receive the request, establish a “non-privileged” session (e.g., a session that is associated with the non-privileged credentials), and provide the root page associated with the user of the non-privileged credentials (step 2.6). The application security server 210 may identify a list of URLs presented in the root page associated with the non-privileged credentials, and generate second list of URLs (step 2.7). The application security server 210 may then generate a “privileged” URL list (step 2.8). For example, the application security server 210 may compare the first URL list and the second URL list, and generate the privileged URL list having the URLs that are present in the first URL list but not in the second URL list. The privileged URL list includes those URLs that should not be accessible by via a non-privileged session (e.g., using non-privileged credentials).
Referring to
In alternative embodiments, a privileged URL list may be pre-defined and may not need to be generated by comparing URL lists generated from root pages accesses using different sets of credentials. For example, the application security server 210 may simply attempt to access a privileged URL identified in a pre-defined privileged URL list using non-privileged credentials, and generate an alert if the attempt is successful (e.g., if the output of the URL request using non-privileged credentials matches the output of the URL request using privileged credentials).
The application security server 210 may include one or more computing devices that identifies whether the application server 220 is hosting webpages or applications that are accessible by unauthorized users. For example, as described above, the application security server 210 may include one or more program modules (e.g., program modules 42 of
The application server 220 may include one or more computing devices that host a web-based application or series of webpages. As described above, the application server 220 provides access to the web-based application or website via user credentials. The application server 220 may present different root pages to different users based on the received user credentials. Different root pages associated with different users may present URLs to different pages based on the pages that different users are permitted to access.
The admin device 230 may include one or more computing devices associated with a site administrator of the application server 220. The admin device 230 may receive alerts identifying webpages that are accessible via non-privileged credentials and/or non-privileged session. Based on receiving the alerts, the admin device 230 may implement policies or modifications to prevent application server 220 from providing webpages to unauthorized users.
The network 240 may include one or more wired and/or wireless networks. For example, the network 240 may include a cellular network (e.g., a second generation (2G) network, a third generation (3G) network, a fourth generation (4G) network, a fifth generation (5G) network, a long-term evolution (LTE) network, a global system for mobile (GSM) network, a code division multiple access (CDMA) network, an evolution-data optimized (EVDO) network, or the like), a public land mobile network (PLMN), and/or another network. Additionally, or alternatively, the network 240 may include a local area network (LAN), a wide area network (WAN), a metropolitan network (MAN), the Public Switched Telephone Network (PSTN), an ad hoc network, a managed Internet Protocol (IP) network, a virtual private network (VPN), an intranet, the Internet, a fiber optic-based network, and/or a combination of these or other types of networks.
The quantity of devices and/or networks in the environment 400 is not limited to what is shown in
As shown in
Process 500 may further include generating a list of URLs included in the “privileged” root page (step 510). For example, the application security server 210 may identify the URLs included or presented in the privileged root page based on, for example, HyperText Markup Language (HTML) data received when accessing the privileged root page.
Process 500 may also include storing images of URL outputs accessed using the privileged credentials (step 515). For example, the application security server 210 may “crawl” or access each of the webpages mapped to the URLs. The output of a webpage request using a URL (e.g., the privileged URL output) may then be stored by the application security server 210. In embodiments, the URL output may be stored in the form of an image (e.g., an image file, such as a .jpg file, a .jpeg file, a .giff file, a .png file etc.). Additionally, or alternatively, the output may be stored in another form (e.g., HTML code, webpage frame data, webpage text, etc.). The application security server 210 may store the privileged URL outputs for each URL.
Process 500 may further include accessing the root page using non-privileged credentials (step 520). For example, the application security server 210 may access the root page of the same application or website as in step 505. However, at this stage, the application security server 210 may access the root page using non-privileged credentials (e.g., credentials that are different than the privileged credentials). As described above, the non-privileged credentials may be associated with a different user than the privileged credentials. The application security server 210 may access the root page using non-privileged credentials by submitting the non-privileged credentials via a form at a login screen. In alternative embodiments, the application security server 210 may access the root page using non-privileged credentials by selecting a link on the login page (e.g., a link for “guest access”).
Process 500 may also include generating a list of URLs included in the “non-privileged” root page (step 525). For example, the application security server 210 may identify the URLs included or presented in the privileged root page based on, for example, HyperText Markup Language (HTML) data received when accessing the privileged root page.
Process 500 may further include generating a privileged URL list (step 530). For example, the application security server 210 may compare the URL list generated at step 510 with the URL list generated at step 525. Based on the two URL lists, the application security server 210 generates a “privileged” URL list that includes those URLs included in the privileged root page, but not included in the non-privileged root page. That is, privileged URL list identifies those URLs that should not be accessible to unauthorized users (e.g., users that attempt to access the URLs using a non-privileged ID).
Process 500 may also include accessing a privileged URL (e.g., a URL in the privileged URL list) using non-privileged credentials (step 535). For example, the application security server 210 may browse to a particular URL in the privileged URL list while logged in with non-privileged credentials (e.g., while logged in as a guest user or as a different user than a user of the privileged credentials). That is, the application security server 210 may browse to a particular URL in the privileged URL list while a non-privileged session is established between the application security server 210 and the application server 220.
Process 500 may further include storing a URL output of the privileged URL accessed using the non-privileged credentials (step 540). For example, the application security server 210 may store the output of a webpage requested using the privileged URL (e.g., a non-privileged URL output) that was accessed using non-privileged credentials. In embodiments, the URL output may be stored in the form of an image (e.g., an image file, such as a .jpg file, a .jpeg file, a .giff file, a .png file etc.). Additionally, or alternatively, the output may be stored in another form (e.g., HTML code, webpage frame data, webpage text, etc.).
Process 500 may also include comparing the privileged URL output with the non-privileged URL output (step 545). For example, the application security server 210 may compare the privileged URL output (generated at step 515) with the non-privileged URL output (generated at step 540). In embodiments, the application security server 210 may compare the URL outputs using image comparison techniques (e.g., pixel-based classification techniques). The application security server 210 may additionally, or alternatively, compare the URL outputs by comparing HTML code associated with the two outputs. Additionally, or alternatively, the application security server 210 may compare text, formatting, metadata, and/or other data associated with the two outputs.
Process 500 may further include determining whether the outputs match (step 550). For example, the application security server 210 may determine whether the outputs match based on comparing the privileged URL output with the non-privileged URL output as described above. In embodiments, the outputs would not match if the accessing the privileged URL using the non-privileged credentials returns a webpage that is different than the webpage returned when the privileged URL is accessed using the privileged credentials (e.g., if the webpage returned when accessed using non-privileged credentials is a redirected webpage, a webpage with an error message, an “access denied” message, etc.).
If the outputs do not match (step 550—NO), the application security server 210 determines that the webpage of the privileged URL is not accessible via non-privileged credentials, and process 500 may return to step 535 to access the next privileged URL in the privileged URL list using non-privileged credentials, store the non-privileged output, and compare the privileged output of the URL with the non-privileged output.
If, on the other hand, the outputs match (step 550—YES), the application security server 210 may output an alert identifying that the webpage (e.g., associated with the privileged URL) is insecure (step 555). In embodiments, the application security server 210 may generate a report identifying privileged URLs that were and were not accessible using the non-privileged credentials. In embodiments, the application security server 210 may output the alert to an admin device 230 associated with a site administrator of the application server 220. As described above, the alert or report may be used to identify insecure webpages so that appropriate actions may be taken to secure the webpages (e.g., adding re-direct or access blocking protocols to the insecure pages).
In embodiments, the steps of process 500 may be in a different order than what is shown in
