"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has cups packages installed that are affected by
multiple vulnerabilities:

  - In macOS High Sierra before 10.13.5, an issue existed in CUPS. This issue was addressed with improved
    access restrictions. (CVE-2018-4180, CVE-2018-4181)

  - The session cookie generated by the CUPS web interface was easy to guess on Linux, allowing unauthorized
    scripted access to the web interface when the web interface is enabled. This issue affected versions prior
    to v2.2.10. (CVE-2018-4300)

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2018-4300. Reason: This candidate is a
    duplicate of CVE-2018-4300. Notes: All CVE users should reference CVE-2018-4300 instead of this candidate.
    All references and descriptions in this candidate have been removed to prevent accidental usage.
    (CVE-2018-4700)

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