MITIGATIONS\n\nMitsubishi Electric released and recommends users update to the latest version: \n\n * GX Works3 - CVE-2022-29826: Download fixed [Ver. 1.090U](<https://www.mitsubishielectric.com/fa/#software>) or later \n\nFor all other listed vulnerabilities, Mitsubishi Electric released mitigations/workarounds for users to follow: \n\n * Ensure malicious actors cannot access project files, configuration files, or security keys stored on the host machine via untrusted networks or hosts. \n * Install antivirus software on the host machine running the software. \n * Encrypt project files and security keys when sending or receiving over the internet. \n * Use the \"authentication with a certificate\" function instead of \"username / password authentication\" for user authentication for access from OPC UA clients to MELSEC iQ-R series OPC UA server modules (MX OPC UA Module Configurator-R only). \n\nCISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:\n\n * Minimize network exposure for all control system devices and/or systems, and ensure they are [not accessible from the Internet](<https://www.cisa.gov/uscert/ics/alerts/ICS-ALERT-10-301-01>).\n * Locate control system networks and remote devices behind firewalls and isolate them from the business network.\n * When remote access is required, use 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 its connected devices.\n\nCISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.\n\nCISA also provides a section for [control systems security recommended practices](<https://www.cisa.gov/uscert/ics/recommended-practices>) on the [ICS webpage on cisa.gov/ics](<https://cisa.gov/ics>) Several recommended practices are available for reading and download, including [Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies](<https://www.cisa.gov/uscert/sites/default/files/recommended_practices/NCCIC_ICS-CERT_Defense_in_Depth_2016_S508C.pdf>).\n\nAdditional mitigation guidance and recommended practices are publicly available on the [ICS webpage on cisa.gov/ics](<https://cisa.gov/ics>) in the Technical Information Paper, [ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies](<https://www.cisa.gov/uscert/ics/tips/ICS-TIP-12-146-01B>).\n\nOrganizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.\n\nNo known public exploits specifically target these vulnerabilities. \n\n### Vendor\n\nMitsubishi Electric\n", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "NONE", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.1, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.2}, "published": "2022-12-06T12:00:00", "type": "ics", "title": "Mitsubishi Electric FA Engineering Software", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2022-25164", "CVE-2022-29825", "CVE-2022-29826", "CVE-2022-29827", "CVE-2022-29828", "CVE-2022-29829", "CVE-2022-29830", "CVE-2022-29831", "CVE-2022-29832", "CVE-2022-29833"], "modified": "2022-12-06T12:00:00", "id": "ICSA-22-333-05", "href": "https://www.cisa.gov/news-events/ics-advisories/icsa-22-333-05", "cvss": {"score": 0.0, "vector": "NONE"}}]}
