Synopsis

The remote anonymous FTP server seems vulnerable to an arbitrary code execution attack.

Description

The remote FTP server allows anonymous users to create directories in one or more locations.

The remote version of this server is vulnerable to a buffer overflow attack in the NLST command which, when coupled with the ability to create arbitrary directories, may allow an attacker to execute arbitrary commands on the remote Windows host with SYSTEM privileges.

Solution

Microsoft has released a set of patches for IIS 5.0, 5.1, 6.0, and 7.0.
