WS_FTP Server SITE CPWD Command Remote Overflow

This script is Copyright (C) 2002-2011 Digital Defense, Inc.


Synopsis :

Arbitrary code can be run on the remote FTP server.

Description :

This host is running a version of WS_FTP FTP server prior to 3.1.2.
Versions earlier than 3.1.2 contain an unchecked buffer in routines
that handle the 'CPWD' command arguments. The 'CPWD' command allows
remote users to change their password. By issuing a malformed
argument to the CPWD command, a user could overflow a buffer and
execute arbitrary code on this host. Note that a local user account
is required.

Solution :

The vendor has released a patch that fixes this issue. Please
