"According to its self-reported version, the instance of GitLab running on the remote web server is 1.0.2 prior to
14.8.6. It is, therefore, affected by the following vulnerabilities:

  - An information disclosure vulnerability exists in GitLab CE/EE due to missing input masking. An
    authenticated, remote attacker can exploit this to view sensitive integration properties in the web
    interface. (CVE-2022-1413)

  - An vulnerability exists in GitLab CE/EE due to missing sanitization of data in Pipeline error messages. An
    authenticated, remote attacker can exploit this to render attacker controlled HTML tags and CSS styling.
    (CVE-2022-1416)

  - An improper access control flaw exists in the CI/CD cache mechanism in GitLab CE/EE. An authenticated,
    remote attacker can exploit this to perform cache poisoning leading to arbitrary code execution in
    protected branches. (CVE-2022-1423)

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