The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue has been discovered in GitLab CE/EE affecting all versions starting from 8.11 before 14.3.6, all     versions starting from 14.4 before 14.4.4, all versions starting from 14.5 before 14.5.2. Under specific     condition an unauthorised project member was allowed to delete a protected branches due to a business     logic error. (CVE-2021-39931)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of GitLab installed on the remote host is affected by a vulnerability, as follows:

  - An issue has been discovered in GitLab CE/EE affecting all versions starting from 8.11 before 14.3.6, all     versions starting from 14.4 before 14.4.4, all versions starting from 14.5 before 14.5.2. Under specific     condition an unauthorised project member was allowed to delete a protected branches due to a business     logic error. (CVE-2021-39931)

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

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 3507bfb3-85d5-11ec-8c9c-001b217b3468 advisory.

  - An authorization logic error in the External Status Check API in GitLab EE affecting all versions starting     from 14.1 before 14.3.6, all versions starting from 14.4 before 14.4.4, all versions starting from 14.5     before 14.5.2, allowed a user to update the status of the check via an API call (CVE-2021-39943)

    GitLab was vulnerable to a blind SSRF attack through the Project Import feature. (CVE-2022-0136)

  - A vulnerability was discovered in GitLab starting with version 12. GitLab was vulnerable to a blind SSRF     attack since requests to shared address space were not blocked. (CVE-2022-0249)

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

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the b299417a-5725-11ec-a587-001b217b3468 advisory.
