"A vulnerability in Cisco Unified IP Phones could allow an
unauthenticated, remote attacker to impersonate another user's phone
if the Cisco Unified Communications Manager (CUCM) is in secure mode.
This vulnerability is due to improper key generation during the
manufacturing process that could result in duplicated manufactured
keys installed on multiple devices. An attacker could exploit this
vulnerability by performing a machine-in-the-middle attack on the
secure communication between the phone and the CUCM. A successful
exploit could allow the attacker to impersonate another user's phone.
This vulnerability cannot be addressed with software updates. There is
a workaround that addresses this vulnerability.

This plugin only works with Tenable.ot.
