Language:

Synopsis

The remote FTP server is affected by a remote denial of service vulnerability.

Description

The remote host is running Active FTP server, a shareware FTP server for Windows-based systems.

There is a flaw in the version of ActiveFTP which may allow an attacker to crash this service remotely by sending an overly long argument to various FTP commands (USER, CWD, and more). The attack can only be performed without authentication through the USER command.

A successful exploit will result in a denial of service and may potentially allow the attacker to execute arbitrary code in the context of the affected application.

Solution

There is no known solution at this time.
