Johnson Controls Software House iSTAR Configuration Utility (ICU) Tool

03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
  • Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.58% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 47.7% of scored records. A rank, not a probability.
NVD base score
8.8 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

• 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.
