Jenkins LTS < 2.414.2 / Jenkins weekly < 2.424 Multiple Vulnerabilities

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 2.414.2 or Jenkins weekly prior to 2.424. It is, therefore, affected by multiple vulnerabilities:

 - Jenkins 2.50 through 2.423 (both inclusive), LTS 2.60.1 through 2.414.1 (both inclusive) does not exclude sensitive build variables (e.g., password parameter values) from the search in the build history widget, allowing attackers with Item/Read permission to obtain values of sensitive variables used in builds by iteratively testing different characters until the correct sequence is discovered. (CVE-2023-43494)

 - In Jenkins 2.423 and earlier, LTS 2.414.1 and earlier, processing file uploads using the Stapler web framework creates temporary files in the default system temporary directory with the default permissions for newly created files, potentially allowing attackers with access to the Jenkins controller file system to read and write the files before they are used. (CVE-2023-43497)

 - In Jenkins 2.423 and earlier, LTS 2.414.1 and earlier, processing file uploads using MultipartFormDataParser creates temporary files in the default system temporary directory with the default permissions for newly created files, potentially allowing attackers with access to the Jenkins controller file system to read and write the files before they are used. (CVE-2023-43498)

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 2.424 or later, or Jenkins LTS to version 2.414.2 or later.
