Executive Summary

This vulnerability is an authorization bypass in iFlytek astron-agent up to version 1.1.2. It affects the Console Knowledge-List Endpoint function FileInfoV2Service.listKnowledgeByPage. By manipulating the space-id argument, an attacker can bypass authorization checks and access files they should not be able to access. The exploit is publicly available and requires a valid low-privilege JWT but does not involve authentication bypass.

Detection Guidance

To detect this vulnerability, monitor HTTP requests to the Console knowledge-list endpoint for the presence of a space-id header. Check if requests without this header are denied while identical requests with an arbitrary space-id header return unauthorized data. Use the PoC script from Resource 1 to test endpoints by sending requests with and without the space-id header and comparing responses.

Impact Analysis

An attacker could exploit this to read files they are not authorized to access, such as test files owned by other accounts. This could lead to unauthorized data exposure or information leakage. The impact is limited to read-only access and requires the attacker to have a valid low-privilege JWT.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements in GDPR and HIPAA. Organizations using this software may fail compliance audits if they cannot demonstrate adequate protection against such authorization bypasses.

Mitigation Strategies

Immediately update iFlytek astron-agent to the latest version beyond 1.1.2. If no update is available, restrict access to the Console knowledge-list endpoint via network policies or firewall rules. Implement strict validation for the space-id header to ensure it matches the user's authorized context. Monitor logs for unauthorized access attempts using the PoC method.
