✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement proper input validation and parameterized queries in the affected ajax.php file.
Edit /ajax.php to validate and sanitize the 'id' parameter before database operations
WAF Rule Implementation

- Restrict network access to the application using firewall rules
- Implement rate limiting and monitoring on the /ajax.php endpoint
🔍 How to Verify
Check if Vulnerable:
Test the /ajax.php?action=delete_block endpoint with SQL injection payloads like ' OR '1'='1Check Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple requests to /ajax.php?action=delete_block with SQL keywords
Network Indicators:
- HTTP requests containing SQL injection patterns to the vulnerable endpoint
SIEM Query:
source="web_logs" AND uri="/ajax.php" AND query="action=delete_block" AND (query CONTAINS "UNION" OR query CONTAINS "SELECT" OR query CONTAINS "OR '1'='1")
