CVE-2020-11981 — AI Deep Analysis Summary

Q1What is this vulnerability? (Essence + Consequences)

🚨 **Essence**: Apache Airflow suffers from **OS Command Injection**. <br>💥 **Consequences**: Attackers can execute **arbitrary commands** on the system. This breaks the core security of the workflow platform.

Q2Root Cause? (CWE/Flaw)

🛡️ **Root Cause**: The flaw lies in the **CeleryExecutor** configuration.…

Q3Who is affected? (Versions/Components)

📦 **Affected**: Apache Airflow versions **1.10.10 and below**. <br>🔧 **Component**: Specifically impacts setups using **CeleryExecutor** with exposed brokers.

Q4What can hackers do? (Privileges/Data)

🕵️ **Hackers' Power**: Full **Remote Code Execution (RCE)**. <br>📂 **Impact**: They can run any OS command with the privileges of the Celery worker process. This means total control over the server.

Q5Is exploitation threshold high? (Auth/Config)

🔑 **Threshold**: **Medium**. <br>🌐 **Requirement**: The attacker must have **direct network access** to the message broker (Redis/RabbitMQ). It's not a simple web UI exploit; it requires broker connectivity.

Q6Is there a public Exp? (PoC/Wild Exploitation)

💣 **Public Exp?**: **YES**. <br>📂 **Evidence**: Multiple PoCs exist on GitHub (e.g., Nuclei templates, Vulhub). Wild exploitation is possible if the broker is exposed.

Q7How to self-check? (Features/Scanning)

🔍 **Self-Check**: Scan for **Apache Airflow** instances. <br>📡 **Focus**: Check if **CeleryExecutor** is enabled AND if the **Redis/RabbitMQ** ports are open to the public or untrusted networks.

Q8Is it fixed officially? (Patch/Mitigation)

🩹 **Official Fix**: **YES**. <br>✅ **Action**: Upgrade Apache Airflow to a version **newer than 1.10.10**. The vendor has addressed this injection flaw.

Q9What if no patch? (Workaround)

🚧 **No Patch?**: **Isolate the Broker**. <br>🔒 **Workaround**: Ensure Redis/RabbitMQ is **NOT** directly accessible from untrusted networks. Use strict firewall rules or internal networks only.

Q10Is it urgent? (Priority Suggestion)

⚡ **Urgency**: **HIGH**. <br>🚨 **Priority**: If you use CeleryExecutor and have exposed brokers, patch **IMMEDIATELY**. This is a critical RCE vulnerability with available exploits.
