Synopsis

The Microsoft Team Foundation Server or Azure DevOps Server installation on the remote host is affected by

Description

The Microsoft Team Foundation Server or Azure DevOps Server installation on the remote host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

- An elevation of privilege vulnerability exists when Azure DevOps Server 2019 does not properly enforce project permissions. An attacker who exploited the vulnerability could add GitHub repositories to a project without having the proper access granted to their account. (CVE-2019-0875)

- A spoofing vulnerability that could allow a security feature bypass exists in when Team Foundation Server does not properly sanitize user provided input. An attacker who exploited the vulnerability could trick a user into loading a page containing malicious content.
An authenticated attacker could exploit the vulnerability by sending a specially crafted payload to the Team Foundation Server, which would get executed in the context of the user every time a user visits the compromised page. (CVE-2019-0857)

- A spoofing vulnerability exists in Microsoft Team Foundation Server when it fails to properly handle web requests. An attacker who successfully exploited the vulnerability could perform script or content injection attacks, and attempt to trick the user into disclosing sensitive information. An attacker could also redirect the user to a malicious website that could spoof content or the vulnerability could be used as a pivot to chain an attack with other vulnerabilities in web services.
(CVE-2019-0869)

- A Cross-site Scripting (XSS) vulnerability exists when Team Foundation 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 Team Foundation Server sanitizes user inputs. (CVE-2019-0866, CVE-2019-0867, CVE-2019-0868, CVE-2019-0870, CVE-2019-0871, CVE-2019-0874)
