Detailsinfo

A vulnerability was found in WSO2 API Manager and Identity Server (version now known) and classified as problematic. Affected by this issue is some unknown processing of the component Refresh Token Handler. The manipulation with an unknown input leads to a authorization vulnerability. Using CWE to declare the problem leads to CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. Impacted is confidentiality, integrity, and availability. CVE summarizes:

An incorrect authorization vulnerability exists in multiple WSO2 products, allowing protected APIs to be accessed directly using a refresh token instead of the expected access token. Due to improper authorization checks and token mapping, session cookies are not required for API access, potentially enabling unauthorized operations. Exploitation requires an attacker to obtain a valid refresh token of an admin user. Since refresh tokens generally have a longer expiration time, this could lead to prolonged unauthorized access to API resources, impacting data confidentiality and integrity.

The advisory is shared for download at security.docs.wso2.com. This vulnerability is handled as CVE-2024-2321 since 03/08/2024. The exploitation is known to be difficult. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.
