Communication manipulation via uncleared CDA buffer
Published Jul 10, 2025 · Updated Aug 4, 2025
Sensitive-data reuse in Honeywell Experion PKS and OneWireless WDM allows remote attackers to manipulate CDA communications. The Control Data Access component fails to clear a buffer before reuse, so residual data can enter a later communication and alter its contents. Network access without authentication is sufficient; the documented result is incorrect system behavior and low confidentiality and integrity impact, not a crash or 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=520.1 <=520.2 TCU9
- Affected versionversion=530 <=530 TCU3
