Apache Superset Insecure Default Initialization of Resource Vulnerability

Apache Superset contains an insecure default initialization of a resource vulnerability that allows an attacker to authenticate and access unauthorized resources on installations that have not altered the default configured SECRET_KEY according to installation instructions.

Why patchRisk explained in plain English
Worst-case scenarioIf unpatched

A remote attacker, without authentication, can achieve full data confidentiality loss, arbitrary modification of data, partial service disruption. Federal agencies are required to remediate by 2024-01-29 under CISA BOD 22-01.

How the attack worksNo clicks needed

This is a Insecure Default Initialization of Resource (CWE-1188) vulnerability in Apache Superset. Session Validation attacks in Apache Superset versions up to and including 2.0.1. Installations that have not altered the default configured SECRET_KEY according to installation instructions allow for an attacker to authenticate and access unauthorized resources. This does not affect Superset administrators who have changed the default value for SECRET_KEY config. All superset installations should always set a unique secure random SECRET_KEY. Your SECRET_KEY is used to securely sign all session cookies and encrypting sensitive information on the database. Add a strong SECRET_KEY to your `superset_config.py` file like: SECRET_KEY = <YOUR_OWN_RANDOM_GENERATED_SECRET_KEY> Alternatively you can set it with `SUPERSET_SECRET_KEY` environment variable. Exploitation requires remote network access, higher attack complexity, no authentication required, and no user interaction required.
