CVE-2023-27524: 
Python vulnerability analysis and mitigation

CVE-2023-27524 affects Apache Superset versions up to and including 2.0.1, involving an insecure default configuration vulnerability. The issue stems from installations that have not modified the default configured SECRET_KEY according to installation instructions, allowing attackers to authenticate and access unauthorized resources. The vulnerability was discovered by Naveen Sunkavally from Horizon3.ai and was publicly disclosed in April 2023 (Horizon3 Research, Hacker News).

The vulnerability centers around the use of a default SECRETKEY value in Apache Superset installations. Initially, the SECRETKEY was set to '\x02\x01thisismyscretkey\x01\x02\e\y\y\h', and later changed to 'CHANGEMETOACOMPLEXRANDOMSECRET' in January 2022. The vulnerability received a CVSS v3.1 score of 8.9 (High) from Apache Software Foundation and 9.8 (Critical) from NVD, indicating its severe nature. The SECRET_KEY is used to securely sign session cookies and encrypt sensitive information in the database (NVD).

The vulnerability's impact is significant, affecting approximately 2,124 out of 3,176 publicly-accessible Superset servers. Successful exploitation allows attackers to gain administrative access, execute remote code, harvest credentials, and compromise connected data. The affected installations include systems across large corporations, small companies, government agencies, and universities (Horizon3 Research).

The vulnerability was addressed in Apache Superset version 2.1, released on April 5, 2023, which prevents the server from starting if configured with a default SECRETKEY. Users must generate a unique secure random SECRETKEY and configure it in their 'supersetconfig.py' file or set it using the 'SUPERSETSECRETKEY' environment variable. Additionally, since sensitive information is encrypted with the SECRETKEY, data must be re-encrypted with the new key after changing it (Horizon3 Research).
