OVERVIEW
Bill Voltmer of Elation Technologies LLC has identified vulnerabilities in
OmniMetrixs OmniView web application. OmniMetrix has produced a new software
version for its web interface that mitigates these vulnerabilities.
These vulnerabilities could be exploited remotely.
AFFECTED PRODUCTS
The following OmniView versions are affected:
OmniView, Version 1.2
IMPACT
Exploiting these vulnerabilities could compromise account credentials that may
allow an attacker to control the operation of backup generators connected to
the compromised account.
Impact to individual organizations depends on many factors that are unique to
each organization. NCCIC/ICS-CERT recommends that organizations evaluate the
impact of these vulnerabilities based on their operational environment,
architecture, and product implementation.
BACKGROUND
OmniMetrix is a US-based company that is headquartered in Buford, Georgia.
The affected web interface, OmniView, is a data management control center that
is used to monitor and control backup generators. OmniView is only accessible
from OmniMetrixs web site. According to OmniMetrix, its services are deployed
across several sectors including Commercial Facilities and Energy. OmniMetrix
estimates that its services are primarily used in the United States with a
small number of users in Europe, Asia, and South America.
