A vulnerability, which was classified as problematic, has been found in PHPGurukul Land Record System 1.0. This issue affects some unknown processing of the file /admin/edit-propertytype.php. The manipulation of the argument Property Type leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.
PHPGurukul Land Record System 1.0 suffers from a critical cross-site scripting (XSS) vulnerability, allowing attackers to inject malicious scripts into the application. This flaw, located in the /admin/edit-propertytype.php file, enables remote attackers to compromise user sessions and potentially gain unauthorized access to sensitive data. Successful exploitation can lead to data theft and system compromise.
Step 1: Payload Delivery: An attacker crafts a malicious payload containing JavaScript code (e.g., <script>alert('XSS')</script>).
Step 2: Parameter Manipulation: The attacker submits the crafted payload as the Property Type parameter value through a POST request to /admin/edit-propertytype.php.
Step 3: Server-Side Processing: The server receives the request and processes the input, likely storing the Property Type value in a database or displaying it directly on the page.
Step 4: Vulnerable Rendering: When the application renders the edit-propertytype.php page, it includes the unsanitized Property Type value in the HTML response.
Step 5: Code Execution: The victim's browser receives the HTML response containing the malicious JavaScript code. The browser then executes the injected JavaScript code, leading to the XSS vulnerability being exploited. This could be used for session hijacking, defacement, or other malicious actions.
The vulnerability stems from insufficient input validation and output encoding on the Property Type parameter within the /admin/edit-propertytype.php file. The application fails to properly sanitize user-supplied input before rendering it in the HTML response. This allows attackers to inject arbitrary JavaScript code, which is then executed in the context of the victim's browser. The root cause is a lack of proper input sanitization and output encoding (e.g., HTML entity encoding) of the Property Type parameter. Specifically, the application likely directly embeds the user-provided input into the HTML without escaping special characters like < and >. This allows for the injection of malicious HTML and JavaScript code.
While no specific APTs are directly linked to this CVE, the availability of a public exploit increases the risk of exploitation by various threat actors, including script kiddies and opportunistic attackers. The vulnerability's simplicity makes it attractive for widespread exploitation. This vulnerability is not currently listed in CISA KEV.
Web application firewall (WAF) logs showing suspicious POST requests to /admin/edit-propertytype.php with potentially malicious payloads (e.g., JavaScript code) in the Property Type parameter.
Network traffic analysis revealing unusual HTTP requests containing XSS payloads.
Server-side logs indicating unexpected behavior or errors related to the edit-propertytype.php file.
Security Information and Event Management (SIEM) alerts triggered by suspicious activity patterns, such as multiple failed login attempts followed by XSS attempts.
Implement input validation to strictly enforce the expected format and content of the Property Type parameter. Reject or sanitize any input that does not conform to the expected format.
Apply output encoding (e.g., HTML entity encoding) to all user-supplied data before rendering it in the HTML response. This will prevent the browser from interpreting the injected code as HTML.
Update to a patched version of PHPGurukul Land Record System that addresses this vulnerability (if available).
Implement a Web Application Firewall (WAF) to filter out malicious requests and block XSS attempts.
Regularly scan the application for vulnerabilities using automated tools.
Review and harden the web server configuration to mitigate potential attack vectors.
