Jenkins Enterprise and Operations Center < 2.303.30.0.4 / 2.319.2.9 RCE (CloudBees Security Advisory 2022-01-28)

medium Nessus Plugin ID 157338

Language:

Synopsis

A job scheduling and management system hosted on the remote web server is affected by a remote code execution vulnerability.

Description

The version of Jenkins Enterprise or Jenkins Operations Center running on the remote web server is 2.303.x prior to 2.303.30.0.4, or 2.x prior to 2.319.2.9. It is, therefore, affected by a remote code execution vulnerability in the Kubernetes Client API. An authenticated, local attacker can exploit this, by entering YAML that would be processed by the Kubernetes Client API.

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

Solution

Upgrade Jenkins Enterprise or Jenkins Operations Center to version 2.303.30.0.4, 2.319.2.9, or later.
