Does this matter?

Lower severity and a low EPSS score (0.50%). Track it; it rarely justifies an emergency change on its own.

Description

A vulnerability in the XML service of Cisco IP Phone firmware could allow an unauthenticated, remote attacker to initiate phone calls on an affected device. This vulnerability exists because bounds-checking does not occur while parsing XML requests. An attacker could exploit this vulnerability by sending a crafted XML request to an affected device. A successful exploit could allow the attacker to initiate calls or play sounds on the device.
