Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Gogs/Gitea Git Hook Command Injection. ๐ **Consequences**: Authenticated users can inject shell commands via `post-receive` hooks. ๐ฅ **Result**: Remote Code Execution (RCE) on the server.โฆ
๐ ๏ธ **Root Cause**: Insecure handling of Git Hooks. ๐ **Flaw**: The system allows execution of arbitrary scripts in hooks without sufficient sanitization.โฆ
๐ป **Privileges**: Full OS command execution. ๐๏ธ **Access**: Server-level access (not just repo-level). ๐ **Data**: Can read/write any file the service user can access.โฆ
๐ **Auth Required**: YES. Must be an authenticated user. ๐ก๏ธ **Config**: Needs 'May create git hooks' permission. ๐ **Threshold**: Medium. Not zero-click, but easy for internal users or leaked credentials.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp**: YES. ๐ **PoC**: Available on GitHub (p0dalirius, Mohnad-AL-saif). ๐งช **Scanner**: Nuclei templates exist. ๐ **Wild Exp**: Possible if credentials are compromised or permissions are loose.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Look for 'ENABLE_GIT_HOOKS' in config. ๐ **Scan**: Check if users can create hooks. ๐ก๏ธ **Tool**: Use Nuclei template `CVE-2020-14144.yaml`. ๐ **Visual**: Inspect repo hooks directory for suspicious scripts.
Q8Is it fixed officially? (Patch/Mitigation)
๐ ๏ธ **Official Fix**: Vendor states 'Not a Vulnerability'. ๐ข **Stance**: It's a documented feature with warnings. โ ๏ธ **Mitigation**: Restrict hook creation permissions.โฆ
โก **Urgency**: High for Admins. ๐ฏ **Priority**: Critical if hooks are enabled. ๐ **Risk**: Low if hooks are disabled. ๐จ **Action**: Review permissions immediately. ๐ **Alert**: Even if 'not a bug', the impact is RCE.
