WU-FTPD MAIL_ADMIN Function Remote Overflow

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

Th remote Wu-FTPD server fails to properly check bounds on a pathname
when Wu-Ftpd is compiled with MAIL_ADMIN enabled resulting in a buffer
overflow. With a specially crafted request, an attacker can possibly
execute arbitrary code as the user Wu-Ftpd runs as (usually root)
resulting in a loss of integrity, and/or availability.

It should be noted that this vulnerability is not present within the
default installation of Wu-Ftpd.

The server must be configured using the 'MAIL_ADMIN' option to notify
an administrator when a file has been uploaded.

*** Nessus solely relied on the banner of the remote server
*** to issue this warning, so it may be a false positive.
