MEDIUM 6.1EPSS 0.80%

Does this matter?

Lower severity and a low EPSS score (0.80%). Track it; it rarely justifies an emergency change on its own.

Description

Cybele Thinfinity VirtualUI 2.5.17.2 allows HTTP response splitting via the mimetype parameter within a PDF viewer request, as demonstrated by an example.pdf?mimetype= substring. The victim user must load an application request to view a PDF, containing the malicious payload. This results in a reflected XSS payload being executed.
