🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Consider applying input validation and parameterized queries manually to the /updateAgent.php file.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests to /updateAgent.php.
Input Validation Filter
allAdd server-side validation to only accept numeric values for agent_id parameter.
Add to updateAgent.php: if(!is_numeric($_POST['agent_id'])) { die('Invalid input'); }
🧯 If You Can't Patch
- Block external access to /updateAgent.php using firewall rules or .htaccess restrictions.
- Implement database user with minimal permissions (read-only if possible) for the application.
🔍 How to Verify
Check if Vulnerable:
Test the /updateAgent.php endpoint with SQL injection payloads like agent_id=1' OR '1'='1 and observe database errors or unexpected behavior.Check Version:
Check application version in source code files or admin panel if available.Verify Fix Applied:
After applying fixes, test with the same SQL injection payloads and verify they are rejected or properly handled without database errors.📡 Detection & Monitoring
Log Indicators:
- Multiple requests to /updateAgent.php with SQL keywords (UNION, SELECT, INSERT, etc.) in parameters
- Database error messages in application logs
Network Indicators:
- HTTP POST requests to /updateAgent.php containing SQL syntax in agent_id parameter
SIEM Query:
source="web_logs" AND uri_path="/updateAgent.php" AND (agent_id="*'*" OR agent_id="*UNION*" OR agent_id="*SELECT*")
