"The remote NewStart CGSL host, running version MAIN 6.06, has docker-ce packages installed that are affected by a
vulnerability:

  - Moby is an open-source project created by Docker to enable software containerization. The classic builder
    cache system is prone to cache poisoning if the image is built FROM scratch. Also, changes to some
    instructions (most important being HEALTHCHECK and ONBUILD) would not cause a cache miss. An attacker with
    the knowledge of the Dockerfile someone is using could poison their cache by making them pull a specially
    crafted image that would be considered as a valid cache candidate for some build steps. 23.0+ users are
    only affected if they explicitly opted out of Buildkit (DOCKER_BUILDKIT=0 environment variable) or are
    using the /build API endpoint. All users on versions older than 23.0 could be impacted. Image build API
    endpoint (/build) and ImageBuild function from github.com/docker/docker/client is also affected as it the
    uses classic builder by default. Patches are included in 24.0.9 and 25.0.2 releases. (CVE-2024-24557)

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