"A vulnerability in the web application for Cisco IP Phones could allow
an unauthenticated, remote attacker to execute code with root
privileges or cause a reload of an affected IP phone, resulting in a
denial of service (DoS) condition. The vulnerability exists because
the affected software fails to check the bounds of input data. An
attacker could exploit this vulnerability by sending a crafted HTTP
request to the web server of a targeted device. A successful exploit
could allow the attacker to remotely execute code with root privileges
or cause a reload of an affected IP phone, resulting in a DoS
condition.
