CVE-2021-22205: Gitlab CE/EE – Remote Code Execution

漏洞描述

GitLab CE/EE starting from 11.9 does not properly validate image files that were passed to a file parser, resulting in a remote command execution vulnerability. 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. Tooling to find relevant hashes based on the semantic version ranges specified in the CVE is linked in the references section below.
