DESCRIPTION:
Shawn Merdinger has reported a security issue in Clipcomm CWP-100 and
Clipcomm CP-100E, which can be exploited by malicious people to
disclose system information, manipulate certain information, and
bypass certain security restrictions.

The problem is caused due to the phone allowing connections to an
undocumented debug service on port 60023/tcp. This can be exploited
to gain access to a configuration/debug shell without being
authenticated.

This can further be exploited to disclose or manipulate certain
information, reset the phone to factory settings, or make phone
calls.

The security issue has been reported in the following products:
* Clipcomm CWP-100 firmware version 1.1.60
* Clipcomm CP-100E firmware version 1.1.12

Other versions may also be affected.

SOLUTION:
Restrict use to within trusted networks only.
