Microsoft Security Bulletin MS12-061 - Important
Vulnerability in Visual Studio Team Foundation Server Could Allow Elevation of Privilege (2719584)
Published: Tuesday, September 11, 2012
Version: 1.0
General Information
Executive Summary
This security update resolves a privately reported vulnerability in Visual Studio Team Foundation Server. The vulnerability could allow elevation of privilege if a user clicks a specially crafted link in an email message or browses to a webpage that is used to exploit the vulnerability. In all cases, however, an attacker would have no way to force users to perform these actions. Instead, an attacker would have to convince users to visit a website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker's website.
This security update is rated Important for all supported editions of Microsoft Visual Studio Team Foundation Server 2010. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerability by correcting how the Team Foundation Server site validates input parameters. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
