Patch Version: UNKNOWN
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
Check vendor website for updates; if unavailable, implement input validation and parameterized queries in /del_room.php.
🔧 Temporary Workarounds
Input Validation and Sanitization
PHPAdd server-side validation to ensure ID parameter contains only numeric values before processing.

- Restrict network access to the management system using firewall rules to allow only trusted IPs.
- Implement database user with minimal privileges (SELECT only if possible) for the application.
🔍 How to Verify
Check if Vulnerable:
Test /del_room.php with SQL injection payloads like ' OR '1'='1 in ID parameter and check for database errors or unexpected behavior.Check Version:
Check system documentation or admin panel for version information; typically displayed in footer or about page.Verify Fix Applied:
After applying fixes, retest with same payloads; successful fix should return error messages or reject invalid input without executing SQL.📡 Detection & Monitoring
Log Indicators:
