"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.");
