Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

Description

A vulnerability in Cisco Finesse could allow an unauthenticated, remote attacker to load arbitrary files from remote locations into an active user session on an affected device, possibly leading to browser-based attacks. This vulnerability is due to insufficient validation of user-supplied input for HTTP requests that are sent to an affected device. An attacker who has knowledge of the address of the affected device could exploit this vulnerability by persuading a user to click a crafted link that contains the affected device address. A successful exploit could allow the attacker to conduct browser-based attacks and execute arbitrary script code in the context of the affected interface or access sensitive information on the affected device.
