This vulnerability has a CVSS 3.1 base score of 5.2, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

A reflected cross-site scripting (XSS) vulnerability exists in the management console of multiple WSO2 products due to improper output encoding. By tampering with specific parameters, a malicious actor can inject arbitrary JavaScript into the response, leading to reflected XSS.

Successful exploitation could result in UI manipulation, redirection to malicious websites, or data theft from the browser. However, session-related sensitive cookies are protected with the httpOnly flag, which mitigates the risk of session hijacking.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
