Name of the Vulnerable Software and Affected Versions Cybele Thinfinity VirtualUI version 2.5.17.2

Description The issue allows HTTP response splitting via the mimetype parameter within a PDF viewer request.

For example, an attack could be demonstrated using a request like 'example.pdf?mimetype=' substring.

Recommendations For Cybele Thinfinity VirtualUI version 2.5.17.2, consider restricting access to the PDF viewer request or disabling the mimetype parameter to minimize the risk of exploitation until a patch is available. Avoid using the mimetype parameter in the affected API endpoint until the issue is resolved.
