Synopsis

The instance of JetBrains TeamCity installed on the remote host is affected by multiple vulnerabilities.

Description

 - In JetBrains TeamCity before 2019.2.3, password parameters could be disclosed via build logs.
 (CVE-2020-15829)

 - JetBrains TeamCity before 2019.2.3 is vulnerable to reflected XSS in the administration UI.
