"The remote NewStart CGSL host, running version MAIN 5.04, has docker-ce packages installed that are affected by a
vulnerability:

  - Moby is an open-source project created by Docker to enable software containerization. A bug was found in
    Moby (Docker Engine) where supplementary groups are not set up properly. If an attacker has direct access
    to a container and manipulates their supplementary group access, they may be able to use supplementary
    group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive
    information or gaining the ability to execute code in that container. This bug is fixed in Moby (Docker
    Engine) 20.10.18. Running containers should be stopped and restarted for the permissions to be fixed. For
    users unable to upgrade, this problem can be worked around by not using the `USER $USERNAME` Dockerfile
    instruction. Instead by calling `ENTRYPOINT [su, -, user]` the supplementary groups will be set up
    properly. (CVE-2022-36109)

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