Jenkins LTS < 2.426.3 / Jenkins weekly < 2.442 Multiple Vulnerabilities

critical Nessus Plugin ID 189463

Language:

Synopsis

An application running on a remote web server host is affected by multiple vulnerabilities

Description

According to its its self-reported version number, the version of Jenkins running on the remote web server is Jenkins LTS prior to 2.426.3 or Jenkins weekly prior to 2.442. It is, therefore, affected by multiple vulnerabilities:

 - Jenkins 2.441 and earlier, LTS 2.426.2 and earlier does not disable a feature of its CLI command parser that replaces an '@' character followed by a file path in an argument with the file's contents, allowing unauthenticated attackers to read arbitrary files on the Jenkins controller file system. (CVE-2024-23897)

 - Jenkins 2.217 through 2.441 (both inclusive), LTS 2.222.1 through 2.426.2 (both inclusive) does not perform origin validation of requests made through the CLI WebSocket endpoint, resulting in a cross-site WebSocket hijacking (CSWSH) vulnerability, allowing attackers to execute CLI commands on the Jenkins controller. (CVE-2024-23898)

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 weekly to version 2.442 or later, or Jenkins LTS to version 2.426.3 or later.
