Description Preview
CVE-2023-3127 affects Johnson Controls iSTAR Ultra, iSTAR Ultra LT, iSTAR Ultra G2, and iSTAR Edge G2 access control systems. The vulnerability allows an unauthenticated user to bypass authentication and log into the systems with administrator privileges, potentially giving unauthorized users complete control over the physical access control infrastructure.
Overview
This vulnerability (CWE-287: Improper Authentication) in Johnson Controls iSTAR access control systems enables unauthorized users to log into the affected devices with administrator rights without proper authentication. The affected products are critical components in physical security infrastructures, controlling access to buildings and secure areas. An attacker exploiting this vulnerability could potentially gain full administrative control over the access control system, allowing them to modify access permissions, create unauthorized credentials, or disable security controls. This represents a significant security risk for organizations using these devices to secure their facilities.
Remediation
Organizations using affected iSTAR devices should:
- Apply firmware updates as soon as they become available from Johnson Controls
- Isolate affected devices on a separate network segment with strict access controls
- Implement network-level security controls to restrict access to the management interfaces
- Monitor system logs for unauthorized access attempts
- Contact Johnson Controls technical support for specific remediation guidance for your deployment
- Regularly check the Johnson Controls security advisory page for updates on patches and mitigations
