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