Check if Vulnerable:
Attempt to upload a non-image file (e.g., .php, .txt) to /aboutedit.php while authenticated. If successful, system is vulnerable.Check Version:
# Check system version in admin panel or configuration filesVerify Fix Applied:
Attempt the same upload after applying workarounds; upload should be rejected.📡 Detection & Monitoring
