"The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple
vulnerabilities as referenced in the 402fccd0-5b6d-11ee-9898-00e081b7aa2d advisory.

  - 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)

  - Jenkins 2.423 and earlier, LTS 2.414.1 and earlier does not escape the value of the 'caption' constructor
    parameter of 'ExpandableDetailsNote', resulting in a stored cross-site scripting (XSS) vulnerability
    exploitable by attackers able to control this parameter. (CVE-2023-43495)

  - Jenkins 2.423 and earlier, LTS 2.414.1 and earlier creates a temporary file in the system temporary
    directory with the default permissions for newly created files when installing a plugin from a URL,
    potentially allowing attackers with access to the system temporary directory to replace the file before it
    is installed in Jenkins, potentially resulting in arbitrary code execution. (CVE-2023-43496)

  - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
