Vulnerability Disclosure Report
Public Exposure of NASA MEDITOR API Specification Revealing Internal Endpoints and Authentication Mechanisms
Target:
Vulnerability Type:
Sensitive Data Exposure (Disclosure of Internal API Endpoints & Authentication Mechanisms)
Description
An API specification file (swagger.yaml) was publicly accessible, exposing sensitive internal API endpoints, authentication flows, and infrastructure details. This misconfiguration allowed unauthorized users to view internal API documentation without authentication, increasing the risk of information leakage and potential exploitation.
The exposed API contained details about OAuth2 authentication mechanisms, CSRF token retrieval, and file upload endpoints. While direct API execution may still require authentication, public access to these endpoints could have aided attackers in reconnaissance and potential API abuse.
Impact
- Exposure of Internal API Endpoints: Attackers could analyze API structure and authentication mechanisms for potential weaknesses.
- Risk of Unauthorized API Interaction: Disclosure of API paths, authentication flows, and security definitions increases the risk of unauthorized requests.
- Potential Exploitation: Knowledge of file upload endpoints and security controls could be leveraged for abuse or privilege escalation attempts.
Resolution
- Public access to the API documentation was restricted and placed behind proper authentication controls.
- The repository permissions were updated to prevent unauthorized access.
- Indexing of sensitive documentation files was blocked to prevent accidental exposure.
- API security measures were reviewed to ensure endpoint protection.
The issue has been fully resolved, and the API specification is no longer publicly accessible.
