📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or full system takeover via SQL injection to RCE chain
Likely Case
Unauthorized data access, modification of property records, or database corruption
If Mitigated
Limited impact if input validation and parameterized queries are implemented
🎯 Exploit Status
Exploitation requires admin access to reach the vulnerable endpoint
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Implement parameterized queries in add-propertytype.php
2. Validate and sanitize all user inputs
3. Escape special characters in the propertytype parameter
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to reject malicious SQL characters
// PHP code to sanitize input
$propertytype = mysqli_real_escape_string($conn, $_POST['propertytype']);
Web Application Firewall Rule
allBlock SQL injection patterns in POST requests to /admin/add-propertytype.php
ModSecurity rule: SecRule ARGS_POST:propertytype "@detectSQLi" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Restrict access to /admin/ directory to trusted IP addresses only
- Disable the add-propertytype.php functionality if not required
🔍 How to Verify
Check if Vulnerable:
Test by sending a POST request to /admin/add-propertytype.php with propertytype parameter containing SQL injection payload like ' OR '1'='1Check Version:
Check PHPGurukul Land Record System version in documentation or configuration filesVerify Fix Applied:
Attempt the same SQL injection test and verify it's blocked or sanitized📡 Detection & Monitoring
Log Indicators:
- POST requests to /admin/add-propertytype.php with SQL keywords in parameters
- Database error logs showing SQL syntax errors
Network Indicators:
- Unusual SQL patterns in HTTP POST payloads
- Multiple rapid requests to admin endpoints
SIEM Query:
source="web_logs" AND uri="/admin/add-propertytype.php" AND (payload CONTAINS "UNION" OR payload CONTAINS "SELECT" OR payload CONTAINS "OR '1'='1'")
