Security Updates for Microsoft Team Foundation Server (March 2020)

high Nessus Plugin ID 134380

Language:

Synopsis

The Microsoft Team Foundation Server is affected by multiple vulnerabilities.

Description

The Microsoft Team Foundation Server is missing security updates. It is, therefore, affected by multiple vulnerabilities :

 - A Cross-site Scripting (XSS) vulnerability exists when Azure DevOps Server does not properly sanitize user provided input. An authenticated attacker could exploit the vulnerability by sending a specially crafted payload to the Team Foundation Server, which will get executed in the context of the user every time a user visits the compromised page. The attacker who successfully exploited the vulnerability could then perform cross- site scripting attacks on affected systems and run script in the security context of the current user. The attacks could allow the attacker to read content that the attacker is not authorized to read, execute malicious code, and use the victim's identity to take actions on the site on behalf of the user, such as change permissions and delete content. The security update addresses the vulnerability by ensuring that Azure DevOps Server sanitizes user inputs.
 (CVE-2020-0700)

 - An elevation of privilege vulnerability exists when Azure DevOps Server and Team Foundation Services improperly handle pipeline job tokens. An attacker who successfully exploited this vulnerability could extend their access to a project. (CVE-2020-0758, CVE-2020-0815)

Solution

Microsoft has released the following updates to address these issues:
 - Team Foundation Server 2017 Update 3.1 with patch 10
 - Team Foundation Server 2018 Update 1.2 with patch 8
 - Team Foundation Server 2018 Update 3.2 with patch 10
 - Azure DevOps Server 2019 Update 0.1 with patch 5
 - Azure DevOps Server 2019 Update 1.1 with patch 1

Please refer to the vendor guidance to determine the version and patch to apply.
