Summary
A vulnerability in the Cisco IP 8800 Series Phone web application could allow
an unauthenticated, remote attacker to cause the web server process to become
unavailable, 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 malicious request to the web server, which could cause the service to crash.
A successful exploit could allow the attacker to trigger a buffer overflow and
create a DoS condition on the targeted system.
Cisco has released software updates that address this vulnerability.
