Jenkins Enterprise and Operations Center < 2.222.43.0.2 rev3 / 2.249.30.0.2 rev3 / 2.263.4.1 rev2 Multiple Vulnerabilities (CloudBees Security Advisory 2021-02-24)

high Nessus Plugin ID 155630

Language:

Synopsis

A job scheduling and management system hosted on the remote web server is affected by multiple vulnerabilities.

Description

The version of Jenkins Enterprise or Jenkins Operations Center running on the remote web server is 2.222.x prior to 2.222.43.0.2 rev3, 2.249.x prior to 2.249.30.0.2 rev3, or 2.x prior to 2.263.4.1 rev2. It is, therefore, affected by multiple vulnerabilities, including the following:

- A cross-site request forgery (CSRF) vulnerability in Jenkins Configuration Slicing Plugin 1.51 and earlier allows attackers to apply different slice configurations. (CVE-2021-21617)

- A cross-site request forgery (CSRF) vulnerability in Jenkins Claim Plugin 2.18.1 and earlier allows attackers to change claims. (CVE-2021-21620)

- Jenkins Support Core Plugin 2.72 and earlier provides the serialized user authentication as part of the 'About user (basic authentication details only)' information, which can include the session ID of the user creating the support bundle in some configurations. (CVE-2021-21621)

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

Solution

Upgrade Jenkins Enterprise or Jenkins Operations Center to version 2.222.43.0.2 rev3, 2.249.30.0.2 rev3, 2.263.4.1 rev2 or later.
