Microsoft Security Bulletin MS13-078 - Important

Vulnerability in FrontPage Could Allow Information Disclosure

Published: September 10, 2013

Version: 1.0

General Information

Executive Summary

This security update resolves a privately reported vulnerability in Microsoft FrontPage. The vulnerability could allow information disclosure if a user opens a specially crafted FrontPage document. The vulnerability cannot be exploited automatically; for an attack to be successful a user must be convinced to open the specially crafted document.

This security update is rated Important for all supported editions of Microsoft FrontPage 2003. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerability by ensuring that FrontPage properly handles Document Type Definition (DTD) entities. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Recommendation. Customers can configure automatic updating to check online for updates from Microsoft Update by using the Microsoft Update service. Customers who have automatic updating enabled and configured to check online for updates from Microsoft Update typically will not need to take any action because this security update will be downloaded and installed automatically. Customers who have not enabled automatic updating need to check for updates from Microsoft Update and install this update manually. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871.

For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update at the earliest opportunity using update management software, or by checking for updates using the Microsoft Update service.

I am using an older release of the software discussed in this security bulletin. What should I do? 
The affected software listed in this bulletin has been tested to determine which releases are affected. Other releases are past their support life cycle. For more information about the product lifecycle, see the Microsoft Support Lifecycle website.

It should be a priority for customers who have older releases of the software to migrate to supported releases to prevent potential exposure to vulnerabilities. To determine the support lifecycle for your software release, see Select a Product for Lifecycle Information. For more information about service packs for these software releases, see Service Pack Lifecycle Support Policy.

Customers who require custom support for older software must contact their Microsoft account team representative, their Technical Account Manager, or the appropriate Microsoft partner representative for custom support options. Customers without an Alliance, Premier, or Authorized Contract can contact their local Microsoft sales office.

Important

An information disclosure vulnerability exists in FrontPage that could allow an attacker to disclose the contents of a file on a target system.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2013-3137.

Mitigating Factors

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:

  • The vulnerability cannot be exploited automatically through email. For an attack to be successful a user must open an attachment that is sent in an email message.
  • In a web-based attack scenario, an attacker could host a website that contains a webpage that is used to exploit the vulnerability. In addition, compromised websites and websites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit the vulnerability. In all cases, however, an attacker would have no way to force users to visit these websites. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes users to the attacker's website, and then convince them to open a specially crafted FrontPage file.

Workarounds

Microsoft has not identified any workarounds for this vulnerability.
