🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Apply workarounds or consider migrating to supported software.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the admin/edit_source endpoint.
Input Validation Filter
allImplement server-side input validation to sanitize the 'id' parameter before processing.
🧯 If You Can't Patch
- Block access to the admin/edit_source endpoint at network perimeter or application level.
- Implement parameterized queries or prepared statements in the application code.
🔍 How to Verify
Check if Vulnerable:
Send GET request to /admin/edit_source with SQL injection payload in 'id' parameter and observe database error or data leakage.Check Version:
Check application version in admin interface or configuration files.Verify Fix Applied:
Test with same payload and verify no SQL errors or unexpected data returned.📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in application logs
- Unusual database queries from web server IP
- Multiple failed login attempts after SQL injection
Network Indicators:
- HTTP GET requests to /admin/edit_source with UNION SELECT patterns
- Unusual outbound database connections from web server
SIEM Query:
source="web_logs" AND uri="/admin/edit_source" AND (query_string CONTAINS "UNION" OR query_string CONTAINS "SELECT" OR query_string CONTAINS "--")
