Detailsinfo

A vulnerability was found in WSO2 Micro Integrator, Enterprise Integrator, API Manager and Synapse (version unknown). It has been rated as critical. This issue affects an unknown function of the component Class Mediator. The manipulation of the argument messageContext with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The Class Mediator fails to correctly validate or sanitize `messageContext` properties when they are used to populate dynamic values. This allows authenticated users to potentially access or modify data across different system invocations that should be isolated. This weakness can lead to the disclosure of sensitive information belonging to other users or the unintended modification of system data by authenticated users. The exact impact depends on how `messageContext` properties are utilized within the affected WSO2 products.

The advisory is shared at security.docs.wso2.com. The identification of this vulnerability is CVE-2024-6541 since 07/08/2024. The exploitation is known to be easy.
