A misconfigured Apache Airflow to AWS Account Compromise


My hypothesis became stronger when I did a quick search over Shodan to actually see how many of them are exposed over the internet and vulnerable to CVE-2020–17526. Also to add to this, by default apache airflow doesn’t provide authentication in the older versions. A simple search revealed that there are more than 300 airflow instances publically exposed over the internet without any authentication.

Privilege Escalation

  1. AWS Keys are being hardcoded in the connection tab.
  2. airflow.cfg configuration widely open and exposing postgress Connection string.
