Number: AL16-011
Date: 31 May 2016

Purpose

The purpose of this advisory is to bring attention to vulnerabilities in the Environmental Systems Corporation (ESC) 8832 Data Controller.

Assessment

CCIRC is aware of critical vulnerabilities in the Environmental Systems Corporation (ESC) 8832 Data Controller unit.  These vulnerabilities are remotely exploitable and can allow an attacker to gain administrator level control of the device.

ESC has stated that firmware security updates will not be issued due to hardware limitations in the 8832 Data Controller.   This is despite the official 1 January 2019 end of life for the 8832 Data Controller.  As a result, the vulnerabilities will not be resolved.

CVE References: CVE-2016-4501, CVE-2016-4502

Affected Versions:
- ESC 8832 Data Controller Version 3.02 and earlier

Suggested action

CCIRC recommends that system owners enact their organization’s life-cycle process for affected devices, and test/deploy replacement solutions.  To aid with mitigation of the vulnerabilities, network access to affected devices should be controlled, isolated and protected.  In particular, access to port 80 on affected devices should be restricted.
