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. VULNERABILITY CHARACTERIZATION VULNERABILITY OVERVIEW CLEARTEXT TRANSMISSION OF SENSITIVE INFORMATION[a] The OmniView web application transmits credentials with the HTTP protocol, which could be sniffed by an attacker that may result in the compromise of account credentials. CVE-2016-5786[b] has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).[c] WEAK PASSWORD REQUIREMENTS[d] Insufficient password requirements for the OmniView web application may allow an attacker to gain access by brute forcing account passwords. CVE-2016-5801[e] has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).[f] VULNERABILITY DETAILS EXPLOITABILITY These vulnerabilities could be exploited remotely. EXISTENCE OF EXPLOIT No known public exploits specifically target these vulnerabilities. DIFFICULTY An attacker with low skill would be able to exploit these vulnerabilities. MITIGATION OmniMetrix has deployed a new version of OmniView software that resolves the reported vulnerabilities. OmniMetrix reports that it has implemented the use of HTTPS protocol and enforces strong password requirements. When OmniMetrixs users log into the OmniMetrix web site, they will be prompted to change passwords. OmniMetrix recommends that users log into their accounts as soon as possible to change their passwords: https://webdata.omnimetrix.net/omxphp/omxLogin.php (link is external) For additional information about the new version of OmniView, contact OmniMetrix at: https://www.omnimetrix.net/en/support/customer-support/ (link is external) ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page at: http://ics-cert.us-cert.gov/content/recommended-practices. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. Additional mitigation guidance and recommended practices are publicly available in the ICSCERT Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site (http://ics-cert.us-cert.gov/). Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents. a.
