Jenkins < 2.263.2 LTS / 2.275 Multiple Vulnerabilities

high Nessus Plugin ID 145248

Language:

Synopsis

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

Description

The version of Jenkins running on the remote web server is prior to 2.275 or is a version of Jenkins LTS prior to 2.263.2. It is, therefore, affected by multiple vulnerabilities, including the following:

 - Jenkins 2.274 and earlier, LTS 2.263.1 and earlier allows users with Agent/Configure permission to choose agent names that cause Jenkins to override the global `config.xml` file. (CVE-2021-21605)

 - Jenkins 2.274 and earlier, LTS 2.263.1 and earlier allows attackers with permission to create or configure various objects to inject crafted content into Old Data Monitor that results in the instantiation of potentially unsafe objects once discarded by an administrator. (CVE-2021-21604)

 - Jenkins 2.274 and earlier, LTS 2.263.1 and earlier does not correctly match requested URLs to the list of always accessible paths, allowing attackers without Overall/Read permission to access some URLs as if they did have Overall/Read permission. (CVE-2021-21609)

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 to version 2.275 or later, Jenkins LTS to version 2.263.2 or later.
