Vulnerability in MHTML Could Allow Information Disclosure

  Severity: HIGH
  CVE Identifier: CVE-2011-0096
  Advisory Date: FEB 02, 2011

  DESCRIPTION

This vulnerability is found in Microsoft Windows. When exploited, a remote attacker is able to execute malicious scripts on the infected system when the user visits websites, thus, disclosing any private information from these sites. The impact of exploiting this vulnerability is the same as that caused by server-side cross-site scripting (XSS) vulnerabilities.


Microsoft has noted that this vulnerability existed because of the way MHTML processes requests that are in MIME format. It is possible that a remote attacker can inject a client-side script code as a response to a Web request when users are browsing the Internet using Internet Explorer (IE). The script is capable of spoofing content, disclosing information, or taking any action on affected websites on behalf of the user.
