✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Apply workarounds or upgrade to a secure version if released.

Check if Vulnerable:
Test the npss parameter in rooms.php with SQL injection payloads (e.g., ' OR '1'='1).Check Version:
Check the software version in the application interface or configuration files.Verify Fix Applied:
Verify that SQL injection attempts no longer succeed and input is properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs, errors from database indicating malformed SQL.
Network Indicators:
- HTTP requests to rooms.php with suspicious npss parameter values containing SQL keywords.
SIEM Query:
source="web_logs" AND uri="*rooms.php*" AND (param="*npss=*OR*" OR param="*npss=*UNION*" OR param="*npss=*SELECT*")
