No official patch available. Consider migrating to alternative software or implementing custom fixes with parameterized queries.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint
# Configure WAF to block patterns like: UNION SELECT, OR 1=1, --, ;, etc.
Input Validation Filter
allImplement input validation to sanitize parameters before processing
# PHP example: filter_input(INPUT_GET, 'id', FILTER_VALIDATE_INT);
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement network segmentation to limit database server access
🔍 How to Verify
Check if Vulnerable:
Test the endpoint /hocms/classes/Master.php?f=delete_collection with SQL injection payloads like: id=1' OR '1'='1Check Version:
Check system documentation or configuration files for version informationVerify Fix Applied:
Verify that parameterized queries are implemented and SQL injection attempts return error messages or are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple failed delete_collection requests with SQL syntax
Network Indicators:
- HTTP requests to /hocms/classes/Master.php with SQL keywords in parameters
SIEM Query:
source="web_server" AND uri="/hocms/classes/Master.php" AND (query="*UNION*" OR query="*SELECT*" OR query="*OR 1=1*")
