Jenkins < 2.73.3 / 2.89 Multiple Vulnerabilities

high Nessus Plugin ID 104634

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 2.89 or is a version of Jenkins LTS prior to 2.73.3.
It is, therefore, affected by multiple vulnerabilities :

 - Jenkins contains a flaw that allows traversing outside of a restricted path. The issue is due to the program not properly sanitizing user input, specifically slashes and path traversal style attacks (e.g. '../') supplied via usernames. With a specially crafted username, a remote attacker can overwrite arbitrary files on the system.

 - Jenkins contains a flaw that allows a stored cross-site scripting (XSS) attack. This flaw exists because the program does not validate autocomplete suggestions before returning it to users. This may allow a remote attacker to create a specially crafted request that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.

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 2.89 or later, Jenkins LTS to version 2.73.3 or later.
