"The remote host is affected by the vulnerability described in GLSA-202312-11 (SABnzbd: Remote Code Execution)

  - SABnzbd is an open source automated Usenet download tool. A design flaw was discovered in SABnzbd that
    could allow remote code execution. Manipulating the Parameters setting in the Notification Script
    functionality allows code execution with the privileges of the SABnzbd process. Exploiting the
    vulnerabilities requires access to the web interface. Remote exploitation is possible if users[exposed
    their setup to the internet or other untrusted networks without setting a username/password. By default
    SABnzbd is only accessible from `localhost`, with no authentication required for the web interface. This
    issue has been patched in commits `e3a722` and `422b4f` which have been included in the 4.0.2 release.
    Users are advised to upgrade. Users unable to upgrade should ensure that a username and password have been
    set if their instance is web accessible. (CVE-2023-34237)

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