Anviz CX2 Lite, CX7, CrossChex Access Control Devices Multiple Critical and High Vulnerabilities
Summary
CISA ICS-CERT published an advisory detailing 12 critical and high-severity vulnerabilities affecting Anviz biometric access control devices (CX2 Lite, CX7, and CrossChex). The vulnerabilities include missing authentication, command injection, hardcoded cryptographic keys, and unauthenticated firmware uploads, with CVSS scores ranging from 5.3 to 9.8. Anviz did not respond to CISA's coordination attempts, leaving no vendor-provided patches available.
What changed
CISA ICS-CERT released advisory ICSA-26-106-03 documenting multiple critical and high-severity vulnerabilities in Anviz access control and biometric devices spanning CX2 Lite, CX7, and CrossChex product lines. The most severe vulnerability (CVSS 9.8) involves unauthenticated firmware uploads allowing attackers to execute arbitrary code and obtain reverse shell access. Other vulnerabilities enable unauthorized administrative access, credential disclosure, and full device compromise.
Organizations deploying these devices across critical infrastructure sectors—including healthcare, energy, financial services, defense, and transportation—should immediately identify affected deployments, contact Anviz for remediation guidance, and implement compensating controls such as network isolation and enhanced monitoring. The advisory notes Anviz has not responded to coordination efforts, indicating no vendor-provided patches or official firmware updates are forthcoming.
What to do next

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/or 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/ics. 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/ics 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.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
