Jenkins Enterprise and Operations Center < 2.249.32.0.2 / 2.277.41.0.2 / 2.303.1.6 Multiple Vulnerabilities (CloudBees Security Advisory 2021-08-31)

high Nessus Plugin ID 153890

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.x prior to 2.303.1.6, 2.249.x prior to 2.249.32.0.2, or 2.277.x prior to 2.277.41.0.2. It is, therefore, affected by multiple vulnerabilities, including the following:

- Jenkins Code Coverage API Plugin 1.4.0 and earlier does not apply Jenkins JEP-200 deserialization protection to Java objects it deserializes from disk, resulting in a remote code execution vulnerability.
(CVE-2021-21677)

- Jenkins SAML Plugin 2.0.7 and earlier allows attackers to craft URLs that would bypass the CSRF protection of any target URL in Jenkins. (CVE-2021-21678)

- Jenkins Azure AD Plugin 179.vf6841393099e and earlier allows attackers to craft URLs that would bypass the CSRF protection of any target URL in Jenkins. (CVE-2021-21679)

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 2.249.32.0.2, 2.277.41.0.2, 2.303.1.6 or later.
