Technical details
A path traversal vulnerability (CWE-23) exists in Gogs' organization creation API. The application fails to sanitize organization names, allowing sequences like '../' to be used. Because organization and repository names are used to construct filesystem paths via 'repox.UserPath' and 'repox.RepositoryPath', an attacker can place Git repositories at arbitrary locations. By strategically nesting a repository within the local worktree of another repository, an attacker can overwrite Git hooks (such as 'hooks/update'). When the repository is subsequently interacted with, the malicious hook is executed, resulting in Remote Code Execution (RCE) with the privileges of the Gogs process. This is fixed in version 0.14.3 by implementing 'AlphaDashDot' validation on organization names and using 'pathx.Clean' on filesystem path inputs.
