critical Nessus Plugin ID 151791

Language:

Synopsis

The remote web server is affected by multiple vulnerabilities.

Description

According to its its self-reported version number, the version of JetBrains TeamCity running on the remote host is a version prior to 2020.2.4. It is, therefore, affected by multiple vulnerabilities:
- A command injection vulnerability exists in JetBrains TeamCity. An unauthenticated, remote attacker can exploit this to execute arbitrary commands. (CVE-2021-31915)

 - An arbitrary code execution vulnerability exists in JetBrains TeamCity. An unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands. (CVE-2021-31914)

 - A remote code execution vulnerability exists in JetBrains TeamCity. An unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands. (CVE-2021-31909)

Note that Nessus did not actually test for these issues, but instead has relied on the version found in the server's banner.

Solution

Upgrade to JetBrains TeamCity version 2020.2.4 or later.
