The iSTAR door controllers running firmware prior to version 6.6.B, does not support authenticated communications with ICU, which may allow an attacker to gain unauthorized access

Remedy

• Replace the iSTAR Pro, Edge and eX door controllers with a current generation iSTAR door controller (such as iSTAR Ultra G2) which supports authentication and prevents the ICU from making configuration changes. • Ensure your iSTAR Ultra and Ultra LT door controllers are running firmware 6.6.B or greater.
