Lack of buffer clearing before reuse may result in incorrect system behavior.
The Honeywell Experion PKS
and OneWireless WDM
contains an Integer Underflow
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 a failure during subtraction allowing 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.
