WU-FTPD MAIL_ADMIN Function Remote Overflow

high Nessus Plugin ID 14371

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.

Solution

Upgrade to Wu-FTPd 2.6.3 or later.
