"The Microsoft Team Foundation Server installation on the remote
host is missing security updates. It is, therefore, affected
by multiple vulnerabilities :
- A remote code execution vulnerability exists when Team Foundation
Server (TFS) does not enable basic authorization on the
communication between the TFS and Search services. Without basic
authorization, an attacker could run certain commands on the
Search service. (CVE-2018-8529)
- 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-2018-8602)");
