JetBrains TeamCity < 2019.1.4 Multiple Vulnerabilities

critical Nessus Plugin ID 339326

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 2019.1.4. It is, therefore, affected by multiple vulnerabilities:

- In JetBrains TeamCity before 2019.1.4, a project administrator was able to retrieve some TeamCity server settings. (CVE-2020-11686)

- In JetBrains TeamCity before 2019.1.4, insecure Java Deserialization could potentially allow remote code execution. (CVE-2019-18364)

- In JetBrains TeamCity before 2019.1.4, reverse tabnabbing was possible on several pages. (CVE-2019-18365)

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 2019.1.4 or later.
