PHOENIX CONTACT has reported this vulnerability via to ICS-CERT. 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:N/I:N/A:H). Openswan 2.6.39 and earlier, which is used in the mGuard firmware version 8.0.0 to 8.5.1, allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon restart) via IKEv2 packets that lack expected payloads.ĬVE-2013-6466 has been assigned to this vulnerability. This vulnerability is remotely exploitable. No known public exploits specifically target this vulnerability. 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. #MGUARD VPN DOWNLOAD#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. 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.NCCIC/ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of this vulnerability. Links to updates and additional information can be found in the advisory at the following location: #MGUARD VPN UPDATE#PHOENIX CONTACT and Innominate Security Technologies recommend all users running mGuard devices with affected firmware versions to update to firmware Version 8.5.2 or higher, which fixes this vulnerability. Successful exploitation of this vulnerability could allow attackers to cause a remote denial of service and force a restart of all IPSec connections. The following versions of mGuard firmware versions 8.0.0 to 8.5.1, running on these mGuard Network Security Appliances, are affected: Vulnerability: Null Pointer Dereference AFFECTED PRODUCTS Vendor: PHOENIX CONTACT, Innominate Security Technologies ATTENTION: Remotely exploitable/low skill level to exploit.
