Cyber Security

ICONICS WebHMI products see action across several sectors including commercial facilities, energy, food and agriculture, healthcare and public health, and water and wastewater systems. ICONICS estimates this product sees use primarily in the United States and Europe with a small percentage in Asia.

An attacker can refer to the configuration files. These files store hashes of passwords and other parameters.

CVE-2016-2289 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.8.

No known public exploits specifically target this vulnerability. However, an attacker with a low skill would be able to exploit this vulnerability.

ICONICS recommends users of WebHMI V9 or earlier should avoid exposing the WebHMI product directly to the Internet. This can happen by using firewalls and/or VPNs. Another mitigation option ICONICS recommends would be to upgrade the system to the V10 version of the ICONICS products and the applying security features built into V10.
