Packet disclosure and injection via weak pseudorandom generation
Published Dec 22, 2025 · Updated Dec 22, 2025
Weak pseudorandom generation in Johnson Controls PowerG 53.02 and earlier allows adjacent attackers to read or inject encrypted packets. The implementation uses a weak pseudorandom generator for packet cryptography; Johnson Controls has not disclosed the generator or code locus. Exploitation requires adjacent wireless access but no privileges or user interaction, and it enables packet disclosure or injection rather than host code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=IQHub
- Affected versionversion=IQ Panel 2+ <=2+
- Affected versionversion=IQPanel 4 <=4.6.0
- Affected versionversion=IQ Panels2 <=2
