FileZilla FTP Server < 0.9.6 Multiple DoS

High

Synopsis

The remote host is vulnerable to multiple attack vectors (remote and local).

Description

The remote host is running the FileZilla FTP server. There is a flaw in the remote version of this software that may allow an authenticated attacker to crash the remote host by requesting DOS devices such as CON, NUL, etc., or by misusing the zlib compression mode. In addition, there is a local client flaw within the FileZilla server component. A local user on the FileZilla server who is enticed to initiate an FTP connection to a malicious server can be exploited.

Solution

Upgrade to version 0.9.6 or higher.
