Legal Notice and Terms of Use This product is provided subject to this Notification (https:\u002F\u002Fwww.cisa.gov\u002Fnotification) and this Privacy & Use policy (https:\u002F\u002Fwww.cisa.gov\u002Fprivacy-policy). Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Minimize network exposure for all control system devices and\u002For systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov\u002Fics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov\u002Fics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents. CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks. No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time. These vulnerabilities have a high attack complexity. These vulnerabilities are not exploitable remotely. Revision History Initial Release Date: 2026-10-06 Date Revision Summary 2026-10-06 1 Initial Republication of Johnson Controls Product Security Advisory JCI-PSA-2026-12. Legal Notice and Terms of Use","Two vulnerabilities, CVE-2026-27872 and CVE-2026-27873, have been identified in Johnson Controls EasyIO FG firmware versions up to 2.0b52. These flaws stem from the use of hard-coded credentials and improper privilege management, potentially allowing an attacker to gain full unauthorized access. Johnson Controls has stated that the EasyIO FG series is End-of-Life and End-of-Support, with no patches available, advising users to migrate to newer products and implement strict network segmentation and access controls.","Johnson Controls EasyIO FG firmware vulnerable to unauthorized access due to hard-coded
