"According to its self-reported version number, the version of Jenkins plugins running on the remote web server is
affected by multiple vulnerabilities:

  - Jenkins Build Failure Analyzer Plugin 2.4.1 and earlier does not escape Failure Cause names in build logs,
    resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to create or
    update Failure Causes. (CVE-2023-43499)

  - A cross-site request forgery (CSRF) vulnerability in Jenkins Build Failure Analyzer Plugin 2.4.1 and
    earlier allows attackers to connect to an attacker-specified hostname and port using attacker-specified
    username and password. (CVE-2023-43500)

  - A missing permission check in Jenkins Build Failure Analyzer Plugin 2.4.1 and earlier allows attackers
    with Overall/Read permission to connect to an attacker-specified hostname and port using attacker-
    specified username and password. (CVE-2023-43501)

  - A cross-site request forgery (CSRF) vulnerability in Jenkins Build Failure Analyzer Plugin 2.4.1 and
    earlier allows attackers to delete Failure Causes. (CVE-2023-43502)

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