iSTAR Ultra Security Fail: Vulnerabilities Open Doors to Cyber Attacks
View CSAF: Johnson Controls’ iSTAR door controllers are more vulnerable than a piñata at a kid’s party. With risks like OS Command Injection and default credentials, attackers might just waltz in. Updating to firmware 6.9.3 is like giving your security a cup of coffee—suddenly, it’s alert and ready!

Hot Take:
Johnson Controls’ iSTAR Ultra devices are suffering from a serious identity crisis – they can’t seem to decide if they want to be secure or just let anyone in through the front door. Maybe they should take a page from the nightclub bouncer handbook: no default passwords and definitely no unauthorized access! Until then, let’s hope no one’s planning to break into the Batcave using a rogue USB stick.
Key Points:
- Johnson Controls’ iSTAR Ultra and Edge door controllers have multiple vulnerabilities including OS Command Injection and Use of Default Credentials.
- Vulnerabilities allow attackers to modify firmware and access protected areas.
- Firmware version 6.9.3 fixes and reduces risk for several vulnerabilities.
- Mitigation measures include upgrading devices and employing network restrictions.
- No known public exploitation of these vulnerabilities has been reported yet.
