Finding GitLab instances
The development team at GitLab issued a new critical security release that patches seven recently-disclosed vulnerabilities in GitLab software. Reported by customers, security researchers, and GitLab team members, these vulnerabilities are located in various components of the software and affect both GitLab Community and Enterprise editions:
- CVE-2022-0735 (CVSS “critical” score of 9.6) - Unauthorized users can steal runner registration tokens via quick actions commands
- CVE-2022-0549 (CVSS “medium” score of 6.5) - Unprivileged users can add other users to groups via the API
- CVE-2022-0751 (CVSS “medium” score of 6.5) - snippet content can be manipulated to display inaccurate/misleading data from an unauthorized user
- CVE-2022-0741 (CVSS “medium” score of 5.8) - Environment variables can be leaked via sendmail
- CVE-2021-4191 (CVSS “medium” score of 5.3) - User enumeration of private GitLab instances (with restricted sign-ups) can be possible by unauthenticated users via the GraphQL API
- CVE-2022-0738 (CVSS “medium” score of 4.2) - User passwords can be leaked when adding pull mirrors with SSH credentials
- CVE-2022-0489 (CVSS “low” score of 3.5) - A denial-of-service condition can be trigger by using the math feature with a specific formula in issue comments
Is an update available?
To avoid possible exploitation of the above vulnerabilities, GitLab recommends all admins update to GitLab versions 14.8.2, 14.7.4, and 14.6.5 for Community Edition (CE) and Enterprise Edition (EE) installations. If upgrading instances isn’t viable in the near-term, GitLab does provide a hotpatch for the runner token disclosure vulnerability–the most severe vulnerability of the bunch–for a number of GitLab versions, suitable as a temporary mitigation until a full update can be performed.
