Readycheck to confirm it

GitLab CE/EE contains a hard-coded credentials vulnerability. A hardcoded password was set for accounts registered using an OmniAuth provider (e.g. OAuth, LDAP, SAML), allowing attackers to potentially take over accounts. This template attempts to passively identify vulnerable versions of GitLab without the need for an exploit by matching unique hashes for the application-<hash>.css file in the header for unauthenticated requests. Positive matches do not guarantee exploitability. Affected versions are 14.7 prior to 14.7.7, 14.8 prior to 14.8.5, and 14.9 prior to 14.9.2.

Impact

Successful exploitation of this vulnerability can lead to unauthorized access to sensitive information or unauthorized actions within the GitLab application.

Fix

Tooling to find relevant hashes based on the semantic version ranges specified in the CVE is linked in the reference section below.
