Jenkins Enterprise and Operations Center < 2.249.31.0.5 / 2.289.1.2 Multiple Vulnerabilities (CloudBees Security Advisory 2021-06-02)

medium Nessus Plugin ID 153976

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 2.249.x prior to 2.249.31.0.5, or 2.x prior to 2.289.1.2. It is, therefore, affected by multiple vulnerabilities, including the following:

 - A flaw exists in CloudBees Jenkins due to RBAC role definitions being pushed to connected clients, even when RBAC is not being used. (BEE-177)

 - A cross-site request forgery vulnerability exists in the CloudBees Assurance Plugin due to the plugin not requiring POST requests for the form submission endpoint configuring the update center. An unauthenticated, remote attacker can exploit this, via the HTTP endpoint, allowing attackers to configure the default update center. (BEE-2047)

 - A flaw exists in the BasicDefaultsProvider due to providing invalid roles to the default configuration.
 (BEE-3042)

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 2.249.31.0.5, 2.289.1.2 or later.
