Description

CVE-2024-6541 is a medium severity vulnerability in WSO2 Micro Integrator where the Class Mediator does not properly validate or sanitize messageContext properties used for dynamic values. Authenticated users could exploit this to access or modify data across system invocations that should be isolated, potentially disclosing sensitive information or causing unintended data modification. The impact depends on the specific use of messageContext properties in the affected versions.

Technical Analysis

The vulnerability arises from improper input validation (CWE-20) in the Class Mediator component of WSO2 Micro Integrator. Specifically, messageContext properties are not correctly validated or sanitized when used to populate dynamic values. This flaw allows authenticated users to potentially access or modify data belonging to other users or system invocations that should remain isolated. The exact impact varies based on how these properties are utilized within the affected product versions.

Potential Impact

Authenticated users may gain unauthorized access to sensitive information or modify data across different system invocations that should be isolated. This can lead to confidentiality breaches and integrity issues within the affected WSO2 Micro Integrator deployments. Availability is not impacted according to the CVSS vector.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time. Users should monitor WSO2 advisories for updates and apply patches once available.
