🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
1. Review the Master.php file
2. Implement parameterized queries for all database operations
3. Add input validation for the delete_team function
4. Test thoroughly before deployment
🔧 Temporary Workarounds
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the vulnerable endpoint
Input Validation Filter
allAdd server-side input validation to sanitize parameters before processing
🧯 If You Can't Patch
- Restrict access to the /odfs/classes/Master.php endpoint using network ACLs or authentication requirements
- Implement database monitoring to detect unusual SQL queries and block suspicious activity
🔍 How to Verify
Check if Vulnerable:
Test the /odfs/classes/Master.php?f=delete_team endpoint with SQL injection payloads and monitor database responsesCheck Version:
Check software version in configuration files or admin panelVerify Fix Applied:
Attempt SQL injection tests after implementing fixes and confirm no database manipulation occurs📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed delete_team attempts with malformed parameters
- Unexpected database errors
Network Indicators:
- HTTP requests to Master.php with SQL keywords in parameters
- Unusual traffic patterns to the vulnerable endpoint
SIEM Query:
source="web_logs" AND uri="/odfs/classes/Master.php" AND (param="delete_team" OR query CONTAINS "SQL" OR query CONTAINS "UNION" OR query CONTAINS "SELECT")
