Core FTP < 2.2 build 1785 CWD Command Buffer Overflow

This script is Copyright (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

An FTP client on the remote host is affected by a stack-based buffer
overflow vulnerability.

Description :

The version of Core FTP installed on the remote host is prior to 2.2
build 1785. It is, therefore, affected by a stack-based buffer overflow
vulnerability because user-supplied input is not properly validated when
handling directory names via the 'CWD' command. A remote attacker could
potentially exploit this issue with specially crafted directory names,
resulting in a denial of service or code execution subject to the user's
privileges.
