🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Implement workarounds or manually fix the vulnerable code by adding proper input validation and parameterized queries.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize the 'id' parameter before processing.
Edit /gasmark/editbrand.php and add: $id = intval($_GET['id']);
Web Application Firewall (WAF)

- Implement database user with minimal privileges (read-only if possible) for the application.
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads like: /gasmark/editbrand.php?id=1' OR '1'='1Check Version:
Check the software version in the admin panel or configuration files.Verify Fix Applied:
Test with SQL injection payloads after implementing fixes; should return error or no data manipulation.📡 Detection & Monitoring
