ProFTPD mkdir Buffer Overflow

This script is Copyright (C) 1999-2014 Tenable Network Security, Inc.


Synopsis :

The remote FTP server is vulnerable to a buffer overflow attack.

Description :

It is possible to crash the remote FTP service by creating a large
number of nested directories with names no longer than 255 chars. This
issue is known to affect ProFTPD, although other FTP servers may be
affected as well.

It is likely that a remote attacker can leverage this issue to execute
arbitrary code on the remote host, subject to the privileges under
which the service runs.

Solution :

Configure the service so that directories are not writable by
'anonymous' or any untrusted users.

If running ProFTPD, upgrade to version 1.2.0pre6 or later
otherwise,
contact the vendor to see if an update exists.
