phpBB 2.0.x with Meilad File upload script (up.php mod)
Authenticated user uploads malicious PHP file through up.php, then directly requests the file from uploads directory to execute arbitrary code
Update to patched phpBB version, implement strict whitelist-based file extension validation, disable PHP execution in upload directory via web server configuration
If file paths are returned, the vulnerable Meilad script exists on system; no output indicates phpBB or the mod is not installed. Check directory permissions and PHP execution settings.
