"According to its self-reported version, the instance of GitLab running on the remote web server is prior to 14.7.7
14.8.x prior to 14.8.5, or 14.9.x prior to 14.9.2. It is, therefore, affected by the following vulnerabilities:

  - Adding a very large number of tags to a runner in GitLab CE/EE allows an attacker to impact the performance of
    GitLab. (CVE-2022-1099)

  - Missing filtering in an error message in GitLab CE/EE exposes sensitive information when an include directive
    fails in the CI/CD configuration. (CVE-2022-1120)

  - A lack of appropriate timeouts in GitLab Pages included in GitLab CE/EE allows an attacker to cause unlimited
    resource consumption. (CVE-2022-1121)

  - Missing sanitization of logged exception messages causes potential sensitive values in invalid URLs to be logged.
    (CVE-2022-1157)

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