medium Nessus Plugin ID 339330

Synopsis

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

Description

The version of JetBrains TeamCity installed on the remote host is prior to 2020.2.1. It is, therefore, affected by multiple vulnerabilities:

 - In JetBrains TeamCity before 2020.2.1, a user could get access to the GitHub access token of another user.
 (CVE-2021-25774)

 - In JetBrains TeamCity before 2020.2.1, the server admin could create and see access tokens for any other users. (CVE-2021-25775)

 - In JetBrains TeamCity before 2020.2.1, permissions during user deletion were checked improperly.
 (CVE-2021-25778)

 - In JetBrains TeamCity before 2020.2.1, permissions during token removal were checked improperly.
 (CVE-2021-25777)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to JetBrains TeamCity version 2020.2.1 or later.
