Well this is how I would start: * Most likely the Cisco Call Manager's AND Unity are on a windows platform, as Linux support is not out till 5.0, which I can't even get. * The 'supported' platform is windows 2000, and it will most likely be a win2000 box, so all the usual Windows 2000 exploits should work hopefully * The default location for Cisco CM web admin is : https://ipaddress/ccmadmin/ * The default login/pass is : ccmadministrator/cisco* Check if RDP and VNC is available, the prolly will be...remember a realVNC exploit was just released, check metasploit.
* Use VLAN hopping to get on the voice VLAN * Possibly use CDP packets to get your QoS DSCP markings through * Check the router/gateway and the switches for 'r00ting' them via old http exploits or mainly SNMP hacking * Sniff traffic for 'chatty' cisco protocols that give a bunch of info for enumeration/recon * Sniff VoIP RTP in windows with ethereal or Cain&Able * Sniff VoIP RTP in Linux via ethereal or VOMIT * Use routing protocols for recon or for re-routing * the normal arp spoofing for MITM well that's just a start..........I work exclusively in the Cisco IPT industry and I come from a security background so I would love to chat about this with you/the community:)

Hello, I'm trying to do a pen-test on a Cisco IPT system. Cisco IP telephone are connected on the same network cable as the PC, but are working on another vlan. The access switches have a configuration like : switchport mode access switchport access vlan 123 switchport voice vlan 124I think the negotation with the access switch is done by CDP but I'm not sure.Does anyone have a tool that emulates the PC as a voice device in order to receive a dhcp lease on vlan 124, so I can start to inject ARP MITM with Cain for example ?Kind regards Frank _________________________________________________________________Express yourself instantly with MSN Messenger!
