MS04-023: Vulnerability in HTML Help Could Allow Code Execution (840315)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

Arbitrary code can be executed on the remote host through the web
client.

Description :

The remote host is subject to two vulnerabilities in the HTML Help and
showHelp modules that could allow an attacker to execute arbitrary code
on the remote host.

To exploit these flaws, an attacker would need to set up a rogue website
containing a malicious showHelp URL, and would need to lure a user on
the remote host to visit it. Once the user visits the website, a
buffer overflow would allow the attacker to execute arbitrary commands
with the privileges of the victim user.
