Summary

CVE-2023-27524 is a high-severity Initialization of a Resource with an Insecure Default (CWE-1188) vulnerability in Apache Superset. Its CVSS base score is 8.9 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Default Accounts (T1078.001); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-27524 is a session validation vulnerability affecting Apache Superset versions up to and including 2.0.1. It arises when installations retain the default SECRET_KEY configuration value, which is used to sign session cookies and encrypt sensitive database information, allowing unauthorized authentication to protected resources. The issue is tracked under CWE-1188 and carries a CVSS 3.1 score of 8.9.

An unauthenticated remote attacker can exploit the flaw over the network by leveraging the unchanged default key to forge valid sessions, thereby gaining access to data and functionality that should be restricted. The attack requires no user interaction and can lead to high-impact confidentiality, integrity, and limited availability consequences, though it does not affect deployments where administrators have already replaced the default SECRET_KEY.

Apache advisories instruct all Superset installations to configure a unique, randomly generated SECRET_KEY in the superset_config.py file or via the SUPERSET_SECRET_KEY environment variable, emphasizing that this step must be performed according to installation guidance.

The associated EPSS score reached a peak of 0.9729, indicating that exploitation interest emerged after disclosure and that the vulnerability warrants renewed attention.

Vulnerability Data

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…

more

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.

Hardened baselines and configuration management directly replace insecure defaults with secure settings.

PR.PS-06 mostly match
prevents

Secure development practices include designing products with secure defaults rather than insecure ones.

ID.RA-09 partial match
prevents

Pre-acquisition integrity checks can reject products known to ship with insecure defaults.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Mandating secure baseline templates and immediate replacement of vendor defaults directly stops systems from being deployed with insecure factory settings that attackers can exploit.

prevents

Requiring documented specification, testing, and acceptance of changes ensures that new or modified components are not initialized with insecure default settings that would otherwise be left in production.

none

Requiring suppliers to document secure configuration and implemented security functions reduces the likelihood that products will be initialised with insecure default settings.
