- CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer
Summary
The Honeywell Experion PKS and OneWireless WDM contains a Memory Buffer vulnerability in the component Control Data Access (CDA). An attacker could potentially exploit this vulnerability, leading to an Overread Buffers, which could result in improper index validation against buffer borders leading to remote code execution.
Honeywell recommends updating to the most recent version of Honeywell Experion PKS:
520.2 TCU9 HF1 and 530.1 TCU3 HF1 and OneWireless: 322.5 and 331.1.
The affected Experion PKS products are C300 PCNT02, C300 PCNT05, FIM4, FIM8, UOC, CN100, HCA, C300PM, and C200E. The Experion PKS versions affected are from 520.1 through 520.2 TCU9 and from 530 through 530 TCU3.The OneWireless WDM affected versions are 322.1 through 322.4 and 330.1 through 330.3.

- CWE-226 - Sensitive Information in Resource Not Removed Before Reuse
Summary
The Honeywell Experion PKS and OneWireless WDM
contains Sensitive Information in Resource vulnerability in the component Control Data Access (CDA). An attacker could potentially exploit this vulnerability, leading to a Communication Channel Manipulation, which could result in buffer reuse which may cause incorrect system behavior.
Honeywell also recommends updating to the most recent version of
Honeywell Experion PKS:520.2 TCU9 HF1 and 530.1 TCU3 HF1 and OneWireless: 322.5 and 331.1.
The affected Experion PKS products are
C300, FIM4, FIM8, UOC, CN100, HCA, C300PM, and C200E. The Experion PKS versions affected are 520.1 before
520.2 TCU9 HF1 and 530 before 530 TCU3. The OneWireless WDM affected versions are 322.1 through 322.4 and 330.1 through 330.3.

in the component Control Data Access (CDA). An attacker could potentially exploit this vulnerability, leading to
Input Data Manipulation, which could result in improper integer data value checking during subtraction leading to a denial of service.
Honeywell recommends updating to the most recent version of Honeywell Experion PKS:520.2 TCU9 HF1 and 530.1 TCU3 HF1.
The affected Experion PKS products are C300 PCNT02, C300 PCNT05, FIM4, FIM8, UOC, CN100, HCA, C300PM, and C200E. The Experion PKS versions affected are from 520.1 through 520.2 TCU9 and from 530 through 530 TCU3.
