Endpoint Vulnerability

Internet Explorer XSS Filter Vulnerability

Description

A remote code execution vulnerability exists when the Internet Explorer XSS Filter does not properly validate JavaScript under specific conditions. An attacker who exploited the vulnerability could run arbitrary code with medium-integrity level privileges (the permissions of the current user). In a web-based attack scenario, an attacker could host a website in an attempt to exploit this vulnerability. In addition, compromised websites and websites that accept or host user-provided content could contain specially crafted content that could exploit the vulnerability. However, in all cases, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action. For example, an attacker could trick users into clicking a link that takes them to the attacker's site. The update addresses the vulnerability by fixing how the Internet Explorer XSS Filter validates JavaScript.
