TITLE:
ST FTP Service Directory Traversal Vulnerability

READ ONLINE:
http://www.secunia.com/advisories/8856/

CRITICAL:
Moderately critical

IMPACT:
Exposure of sensitive information

WHERE:
From remote

SOFTWARE:
ST FTP Server 3.x

DESCRIPTION:
A directory traversal vulnerability has been identified in ST FTP
Server. This allows malicious users to access any drive or directory,
which the FTP server process got privileges to.

The problem is that the "cd" command e.g. takes "c:" as a valid
argument.

SOLUTION:
Limit access so that only trusted user got access to the FTP
service.

To limit the impact of directory traversal you could also implement
NTFS and restrict access for the web server process, so that it can
not access files outside the ftp root.
