Jenkins < 2.235.4 LTS / 2.252 Multiple Cross-Site Scripting (XSS) Vulnerabilities

medium Nessus Plugin ID 139726

Language:

Synopsis

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

Description

The version of Jenkins running on the remote web server is prior to 2.252 or is a version of Jenkins LTS prior to 2.235.4. It is, therefore, affected by multiple cross-site scripting vulnerabilities due to improper validation of user-supplied input before returning it to users. An authenticated, remote attacker can exploit this to execute arbitrary script code in a user's browser session.

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 2.252 or later, Jenkins LTS to version 2.235.4 or later.
