Vulnerability CVE-2007-5361
Published: 2007-11-20   Modified: 2012-02-12

Description:
The Communication Server in Alcatel-Lucent OmniPCX Enterprise 7.1 and earlier caches an IP address during a TFTP request from an IP Touch phone, and uses this IP address as the destination for all subsequent VoIP packets to this phone, which allows remote attackers to cause a denial of service (loss of audio) or intercept voice communications via a crafted TFTP request containing the phone's MAC address in the filename.
