CVE-2025-3946
Estado: AplazadaAlta (8.2)—
The Honeywell Experion PKS
and OneWireless WDM
contains a Deployment of Wrong Handler
vulnerability
in the component Control Data Access (CDA). An attacker could potentially exploit this vulnerability, leading to
Input Data Manipulation,
which could result in incorrect handling of packets 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.
