Dear all,
The referred paper lists several severe vulnerabilities with Cisco
systems' SIP-based IP Phone 7960 and its supporting environment. These
vulnerabilities lead to: complete control of a user's credentials; total
subversion of a user's settings for the IP Telephony network, and the
ability to subvert the entire IP Telephony environment. Malicious access
to a user's 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.

I would like to thank Josh Anderson for the help lent me during the
development of the paper.
