Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Apache Airflow < 1.10.11 has a **Command Injection** flaw in its **Example DAGs**. π **Consequences**: Attackers can execute **arbitrary OS commands** on the server, leading to full system compromise.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: The vulnerability stems from unsafe handling of user input within the **Example DAGs** shipped with the software. It allows injection of shell commands directly into the execution environment.β¦
π¦ **Affected**: **Apache Airflow** versions **1.10.10 and earlier**. π’ **Vendor**: Apache Software Foundation. π **Published**: July 16, 2020.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: Run **arbitrary commands** as the user running the Airflow worker/scheduler. π **Impact**: Can access sensitive data, pivot to other systems, or destroy infrastructure.β¦
π **Exploitation Threshold**: **Low to Medium**. β οΈ While often requiring authentication, the vulnerability exists in **Example DAGs** which are loaded by default.β¦
π₯ **Public Exploits**: **YES**. Multiple PoCs are available on GitHub (e.g., `pberba/CVE-2020-11978`, `vulhub`). Automated tools like **Nuclei** also have templates for detection and exploitation.β¦
π **Self-Check**: 1. Check Airflow version (`airflow version`). 2. Look for default **Example DAGs** being enabled. 3. Use Nuclei templates (`CVE-2020-11978.yaml`) for scanning. 4.β¦
β **Official Fix**: **YES**. The vulnerability was fixed in **Apache Airflow 1.10.11**. π **Action**: Upgrade immediately to version 1.10.11 or later.
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: 1. **Disable Example DAGs** in the Airflow configuration (`load_examples = False`). 2. Restrict network access to Airflow UI. 3.β¦
π₯ **Urgency**: **CRITICAL**. π¨ This is a high-impact RCE vulnerability with **public PoCs**. If you are running an older version, patch **IMMEDIATELY** to prevent unauthorized command execution.
