Vulnerability Note VU#434641

Microsoft Internet Explorer may automatically execute HTA files

Original Release date: 11 Apr 2006 | Last revised: 12 Apr 2006

Overview

Microsoft Internet Explorer (IE) fails to properly handle HTA files. This vulnerability may allow a remote attacker to execute arbitrary code.

Description

HTML Application (HTA)


HTML Applications (HTAs) are HTML documents that are executed as trusted applications. HTAs can run script, Java, or ActiveX controls.

The Problem

An error in the way that IE handles HTAs may allow a remote attacker to bypass IE's Security checks and execute an HTA application without a user's consent.

Considerations

More information is available in Microsoft Security Bulletin MS06-013.

Impact

If a remote attacker can persuade a user to access a specially crafted HTML page, that attacker may be able to execute arbitrary code with the privileges of the compromised user.
