The Microsoft Team Foundation Server installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:
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. (CVE-2019-0646)
An information disclosure vulnerability exists when Team Foundation Server does not properly handle variables marked as secret. An authenticated attacker who successfully exploited this vulnerability could view variables that were hidden by other users. (CVE-2019-0647)
