"A vulnerability in the web-based management interface of Session
Initiation Protocol (SIP) Software for Cisco IP Phone 8800 Series
could allow an unauthenticated, remote attacker to bypass
authorization, access critical services, and cause a denial of service
(DoS) condition. The vulnerability exists because the software fails
to sanitize URLs before it handles requests. An attacker could exploit
this vulnerability by submitting a crafted URL. A successful exploit
could allow the attacker to gain unauthorized access to critical
services and cause a DoS condition. This vulnerability affects Cisco
IP Phone 8800 Series products running a SIP Software release prior to
11.0(5) for Wireless IP Phone 8821 and 8821-EX; and 12.5(1)SR1 for the
IP Conference Phone 8832 and the rest of the IP Phone 8800 Series.
Cisco IP Conference Phone 8831 is not affected.

This plugin only works with Tenable.ot.
