The Trivial Cisco IP Phones Compromise
by Ofir Arkin - Founder of the Sys-Security Group
The following paper lists several severe vulnerabilities with Cisco systemsí SIP-based IP Phone 7960 and its supporting environment. These vulnerabilities lead to complete control of a userís credentials, the total subversion of a userís settings for the IP Telephony network, and the ability to subvert the entire IP Telephony environment. Malicious access to a userís credentials could enable "Call Hijacking", "Registration Hijacking", "Call Tracking", and other voice related attacks. The vulnerabilities exist with any deployment scenario, but this paper deals specifically with large scale deployments as recommended by Cisco.
