A vulnerability was found in PHPGurukul Land Record System 1.0. It has been rated as problematic. This issue affects some unknown processing of the file /admin/search-property.php. The manipulation of the argument Search By 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. This flaw allows attackers to inject malicious scripts into the application via the Search By parameter, potentially leading to account compromise and data theft.
Step 1: Payload Delivery: The attacker crafts a malicious payload containing JavaScript code (e.g., <script>alert('XSS')</script>) and injects it into the Search By parameter of a request to /admin/search-property.php.
Step 2: Request Submission: The attacker submits the crafted request to the vulnerable application.
Step 3: Server-Side Processing: The server receives the request and processes it, likely retrieving data based on the Search By parameter.
Step 4: Vulnerable Rendering: The application, without proper sanitization, incorporates the attacker's payload directly into the HTML response.
Step 5: Payload Execution: When a user views the page, the injected JavaScript code executes within the user's browser, allowing the attacker to perform actions such as stealing cookies, redirecting the user, or defacing the website.
The vulnerability stems from insufficient input validation and output encoding within the /admin/search-property.php file. Specifically, the application fails to properly sanitize user-supplied input provided through the Search By parameter before rendering it on the page. This allows an attacker to inject arbitrary HTML and JavaScript code. The root cause is a lack of input validation and output encoding (e.g., HTML entity encoding) for the Search By parameter. The application directly reflects the user-provided input without proper sanitization, leading to the execution of malicious scripts within the context of the vulnerable application.
While no specific APT groups are directly linked to this vulnerability in the provided information, the ease of exploitation makes it attractive to a wide range of attackers, including those seeking to establish a foothold for further attacks. This vulnerability could be leveraged by attackers to perform phishing attacks, credential harvesting, and website defacement. CISA KEV status is undetermined based on the provided information, but the severity and ease of exploitation warrant rapid assessment and remediation.
Web Application Firewall (WAF) logs showing suspicious HTTP requests containing JavaScript payloads in the Search By parameter.
Intrusion Detection System (IDS) alerts triggered by XSS signatures in HTTP requests targeting /admin/search-property.php.
Network traffic analysis revealing unusual HTTP requests with malicious payloads.
Reviewing server-side logs for requests to /admin/search-property.php that contain potentially malicious JavaScript code in the Search By parameter.
Browser-based security tools detecting and blocking XSS attempts.
Implement input validation to strictly control the format and content of the Search By parameter, allowing only expected characters and filtering out potentially malicious code.
Apply output encoding (e.g., HTML entity encoding) to all user-supplied data before rendering it in the HTML response. This prevents the browser from interpreting the injected code as executable JavaScript.
Update to a patched version of PHPGurukul Land Record System that addresses the vulnerability. If no patch is available, consider the following steps.
Implement a Web Application Firewall (WAF) to filter malicious requests.
Regularly scan the application for vulnerabilities using automated tools.
Review and harden the web server configuration to mitigate potential attack vectors.
Educate users about the risks of phishing and social engineering attacks.
