CVE-2024-57686
📋 TL;DR
A reflected Cross-Site Scripting (XSS) vulnerability in PHPGurukul Land Record System v1.0 allows remote attackers to inject malicious scripts via the 'pagetitle' parameter in the contactus.php admin page. This enables execution of arbitrary JavaScript in victims' browsers, potentially compromising admin sessions and system integrity. Organizations using this specific version of the land record system are affected.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal admin session cookies, perform administrative actions, deface the website, or redirect users to malicious sites, potentially leading to full system compromise.
Likely Case
Session hijacking of admin accounts leading to unauthorized data access, modification of land records, or installation of backdoors.
If Mitigated
Limited impact if proper input validation and output encoding are implemented, though some risk remains from social engineering attacks.
🎯 Exploit Status
The vulnerability is in an admin page but appears to be accessible without authentication based on the file path. Public proof-of-concept documentation exists.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Implement input validation and output encoding in /landrecordsys/admin/contactus.php for the 'pagetitle' parameter.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize the 'pagetitle' parameter before processing.
Modify contactus.php to include: $pagetitle = htmlspecialchars($_GET['pagetitle'], ENT_QUOTES, 'UTF-8');
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block XSS payloads targeting the pagetitle parameter.
Add WAF rule: Block requests containing <script> tags or javascript: in pagetitle parameter
🧯 If You Can't Patch
- Restrict access to /landrecordsys/admin/ directory using IP whitelisting or authentication.
- Implement Content Security Policy (CSP) headers to mitigate XSS impact.
🔍 How to Verify
Check if Vulnerable:
Test by accessing /landrecordsys/admin/contactus.php?pagetitle=<script>alert('XSS')</script> and check if script executes.Check Version:
Check system documentation or configuration files for version information.Verify Fix Applied:
After implementing fixes, test with same payload to ensure script does not execute and input is properly sanitized.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to contactus.php with script tags or encoded payloads in pagetitle parameter
- Unusual admin activity following XSS payload requests
Network Indicators:
- HTTP GET requests containing malicious script patterns in query parameters
- Unexpected redirects from the contactus.php page
SIEM Query:
source="web_logs" AND uri="/landrecordsys/admin/contactus.php" AND (query CONTAINS "<script>" OR query CONTAINS "javascript:")
