Serv-U SITE CHMOD Command Multiple Vulnerabilities

This script is Copyright (C) 2004-2014 Astharot


Synopsis :

The remote FTP server is affected by a buffer overflow vulnerability.

Description :

The remote host is running Serv-U FTP Server.

There is a bug in the way the server handles arguments to the SITE
CHMOD requests that could allow an attacker to trigger a buffer
overflow or corrupt memory in the server and disable it remotely
or to potentially execute arbitrary code on the host.

Note that successful exploitation requires access to a writable
directory and will result in code running with Administrator or SYSTEM
privileges by default.
