Critical CVSS 9.8 EPSS 0.12442 2019-07 archive

Executive Summary

A remote code execution vulnerability exists when Azure DevOps Server and Team Foundation Server (TFS) improperly handle user input. An attacker who successfully exploited the vulnerability could execute code on the target server in the context of the DevOps or TFS service account. To exploit the vulnerability, an attacker could submit a specially crafted file to an affected server. If anonymous access is allowed to projects on an affected server, the attacker would not require authentication. The update corrects the way that DevOps Server and TFS process certain file types.
