CVE-2020-15867 — AI Deep Analysis Summary

Q: What is this vulnerability? (Essence + Consequences)

🚨 **Essence**: Gogs Git Hooks allow **OS Command Injection**. 💥 **Consequences**: Remote Code Execution (RCE) & Privilege Escalation. Attackers can run arbitrary commands on the server.

Q: Root Cause? (CWE/Flaw)

🛡️ **Root Cause**: Flaw in **Git Hooks** functionality. ⚠️ **CWE**: Not explicitly listed, but implies **Command Injection**. The UI doesn't warn users of unsafe actions.

Q: Who is affected? (Versions/Components)

📦 **Affected**: Gogs versions **0.5.5** through **0.12.2**. 🔧 **Component**: Git Hooks feature.

Q: What can hackers do? (Privileges/Data)

💀 **Attacker Actions**: Execute **Remote Code** as the Gogs user. 🔓 **Privileges**: Can escalate privileges if non-admin users have hook access.

Q: Is exploitation threshold high? (Auth/Config)

🔑 **Threshold**: **High** (Requires Auth). 👤 **Requirement**: Must be an **authenticated** user. Not fully open to the public internet.

Q: Is there a public Exp? (PoC/Wild Exploitation)

📜 **Exploit Status**: **Yes**, public PoC exists. 🔗 Links: PacketStorm & FZI research. Nuclei templates available.

Q: How to self-check? (Features/Scanning)

🔍 **Self-Check**: Scan for Gogs versions **0.5.5-0.12.2**. 🧪 Test: Check if **Git Hooks** feature is enabled and accessible to non-admins.

Q: Is it fixed officially? (Patch/Mitigation)

🩹 **Fix**: Upgrade Gogs to a version **> 0.12.2**. ✅ Official patch addresses the hook injection flaw.

Q: What if no patch? (Workaround)

🚧 **No Patch?**: Disable **Git Hooks** feature entirely. 🚫 Restrict hook access to **Admins only**. Remove non-admin privileges.

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **High**. ⚡ RCE is critical. Even with auth requirement, lateral movement is easy. Patch immediately!
