🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Remove or restrict access to /check_profile_old.php and implement parameterized queries
🔧 Temporary Workarounds
File Access Restriction
allBlock access to vulnerable PHP file using web server configuration
# Apache: RewriteRule ^check_profile_old\.php$ - [F,L]
# Nginx: location ~ /check_profile_old\.php$ { deny all; }
Input Validation
allAdd strict input validation for profile_id parameter
// PHP: if(!is_numeric($_GET['profile_id'])) { die('Invalid input'); }
🧯 If You Can't Patch
- Implement WAF rules to block SQL injection patterns targeting profile_id parameter
- Restrict database user permissions to read-only for application accounts
