Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.Īdditional mitigation guidance and recommended practices are publicly available in the ICS‑CERT 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 (). ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page at: . ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. Also recognize that VPN is only as secure as the connected devices. When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Locate control system networks and remote devices behind firewalls, and isolate them from the business network. Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet. ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities.
Innominate’s firmware updates are available on its web site at: Innominate also recommends that customers limit access to the administrative interfaces to a minimum via firewall rules.įor additional information on the vulnerability, Innominate’s security advisory is available on its web site at:
#Mguard vpn upgrade#
Innominate recommends that customers using firmware versions older than Version 7, which are no longer being maintained, should upgrade to mGuard firmware Version 8.1.7. Innominate has released firmware patches for the affected versions, Versions 8.0.0 through 8.1.6 that mitigate the vulnerability in the mGuard firmware. DIFFICULTYĪn attacker with a low skill would be able to exploit this vulnerability. No known public exploits specifically target this vulnerability. This vulnerability could be exploited remotely. A CVSS v2 base score of 7.8 has been assigned the CVSS vector string is (AV:N/AC:L/Au:N/C:N/I:N/A:C). It is possible to cause a temporary DoS condition on the VPN daemon on the VPN waiting side if the VPN initiating peer has the option “IPsec compression” enabled. VULNERABILITY CHARACTERIZATION VULNERABILITY OVERVIEW They can be found in many critical infrastructure sectors, including Communications, Critical Manufacturing, and Healthcare and Public Health. The affected products, the mGuard family of products, are industrial security routers. Innominate is a German-based company that sells products worldwide through its international partners. NCCIC/ICS-CERT recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation. Impact to individual organizations depends on many factors that are unique to each organization. Successful exploitation of this vulnerability could result in a DoS condition.
The following mGuard versions are affected:
#Mguard vpn Patch#
Inominate has produced a patch to mitigate this vulnerability. Innominate mGuard has self identified a denial-of-service (DoS) vulnerability in the Innominate mGuard device.
