Apache Superset is a data visualization and exploration platform designed to be deployed as a web-based application, often serving as an interface for users to access business intelligence data. Given its role as a web application platform, it is frequently deployed in environments where it is network-accessible to users, making public-facing or internet-exposed configurations common.

Horizon Alert

Summary of the vulnerability and why it matters

Apache Superset installations that do not change the default secret key are vulnerable. This weakness allows an unauthenticated attacker to access unauthorized resources. The impact can include unauthorized data access and potential system compromise.

  • Vulnerable: Apache Superset default configurations.
  • Weakness: Insecure default secret key.
  • Impact: Unauthorized resource access.

Attack Path

How an attacker could exploit the issue

Exploitation of this vulnerability allows an attacker to bypass authentication and access resources without authorization. This occurs when organizations use default configurations for the SECRET_KEY in Apache Superset. The impact can include unauthorized access to sensitive data and potentially compromise system integrity.

  • Publicly accessible instances.
  • Unauthenticated access to the application.
  • Attacker gains unauthorized control.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability affects Apache Superset installations that have not changed the default secret key. Attackers can exploit this to authenticate and access unauthorized resources. This poses a significant risk to organizations relying on Superset for data visualization and exploration.

  • Attacker skill level: Low
  • Required access or conditions: Network access
  • Business risk or urgency: High

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

Organizations using Apache Superset up to version 2.0.1 may be at risk if the default `SECRET_KEY` has not been changed. This vulnerability could allow an unauthorized attacker to authenticate and access restricted resources. Administrators who have modified the default `SECRET_KEY` are not affected.

  • Identify Superset installations using default `SECRET_KEY`.
  • Update `SECRET_KEY` in configuration.
  • Verify fix and monitor for suspicious activity.

Frequently asked questions

What is the nature of the security vulnerability in Apache Superset?

The vulnerability in Apache Superset, identified as CVE-2023-27524, is related to session validation. Installations that retain the default SECRET_KEY are susceptible to attackers who can then authenticate and access unauthorized resources. This weakness is classified as CWE-1188.

How can an attacker exploit the Apache Superset vulnerability?

An attacker can exploit this vulnerability by leveraging installations of Apache Superset (versions up to 2.0.1) that have not changed the default SECRET_KEY. This allows for unauthenticated access, enabling the attacker to bypass security controls and access unauthorized data or system functionalities.

What is the impact of the Apache Superset vulnerability if exploited?

Exploitation of this vulnerability can lead to significant security breaches, including unauthorized access to sensitive data and potential compromise of system integrity. Attackers can gain unauthorized control over resources within the Superset application.

What is the relevance of the Halo Surface Signal for this Apache Superset vulnerability?

Halo classifies this CVE as 'Likely' due to its nature as a web-based application platform, Apache Superset, which is often network-accessible. This makes public-facing or internet-exposed configurations common, increasing the potential attack surface and relevance of the vulnerability.

What steps should be taken to respond to the Apache Superset vulnerability?

To mitigate this vulnerability, organizations using Apache Superset versions up to 2.0.1 should immediately change the default SECRET_KEY in their `superset_config.py` file or set the `SUPERSET_SECRET_KEY` environment variable to a unique, securely generated key. Administrators who have already changed this default key are not affected.
