Overview
apache-airflow-providers-amazon is a Provider for Apache Airflow. Implements apache-airflow-providers-amazon package
Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF) via the AWS auth manager SAML login flow, where login() discards the AuthnRequest id generated by saml_auth.login() and login_callback() calls process_response() with no request_id. Because python3-saml only validates the InResponseTo field when an id is explicitly supplied, the check is skipped entirely, allowing any SAML assertion signed by the configured IdP to be accepted - including one obtained from a login flow initiated by a different browser. An attacker who can obtain a valid IdP-signed assertion (for example, by initiating their own login and capturing the response) can replay it in a victim's browser session to authenticate as the assertion's subject.
Note: This is only exploitable when the attacker can obtain a valid SAML assertion signed by the configured IdP and present it to the callback endpoint of a different browser session.
