Clipcomm CPW-100E Wireless Mobile IP Phone Open Debug Service
------------------------------------------------------------------------


SUMMARY

" <http://www.clipcomm.co.kr/eng/e_product/e_product_voip_cwp100.html>
Clipcomm's Wi-Fi IP phone, CWP-100, is a low-priced wireless mobile IP
phone that enables users to make or receive phone calls over the IEEE
802.11b wireless network."

An undocumented port and tcp services in Clipcomm CPW-100E wireless mobile
IP phone allow attackers to gain information, change settings, track phone
calls and more.

DETAILS

Vulnerable Systems:
* Clipcomm CPW-100E wireless mobile IP phone Firmware version 1.1.12
(051129)

An undocumented port and debug service on TCP/60023 enables an attacker to
access without authentication the phone's configuration/debug shell via
telnet. The shell access provides the attacker with two levels of access:
1. CLIP account that allows general configuration.
2. USH shell, accessed from within the CLIP shell, that allows an
attacker to enable call tracing and debugging, conduct a factory reset,
write to registers, dump memory, etc.

Attackers can also use the "call" command under the USH shell to call
another phone under the attacker's control from the CPW-100, thereby
turning the phone into a remote monitoring device.
