UTC Fire & Security Master Clock contains hardcoded default administrator login credentials

Vulnerability Note VU#707254

Original Release Date: 2012-02-20 | Last Revised: 2012-07-23

Overview

UTC Fire & Security GE-MC100-NTP/GPS-ZB Master Clock have default administrator login credentials that can not be modified by an administrator.

Description

UTC Fire & Security GE-MC100-NTP/GPS-ZB Master Clock via Zigbee can sync up to 60,000 slave clocks located throughout a campus-area network. An administrator will typically log into the device by supplying credentials to a web-interface. These devices contain a consistent, hardcoded administrative username and password that cannot be changed by the administrator.

Impact

A remote, unauthenticated attacker can view and change system configuration files or other sensitive data.

Solution

We are currently unaware of a practical solution to this problem.

Restrict Access
Do not allow access to the web interface of the UTC Fire & Security GE-MC100-NTP/GPS-ZB Master Clock from untrusted networks.

Block Access to the Web Interface
Blocking access to port 80/tcp will prevent any user, even authorized administrators, from logging into the web-interface, but will not interfere with the UTC Fire & Security GE-MC100-NTP/GPS-ZB Master Clock slave clock syncing.
