The Honeywell Experion PKS contains an Uninitialized Variable in the common Epic Platform Analyzer (EPA) communications. An attacker could potentially exploit this vulnerability, leading to a Communication Channel Manipulation, which results in a dereferencing of an uninitialized pointer leading to a denial of service.

Honeywell recommends updating to the most recent version of

Honeywell Experion PKS: 520.2 TCU9 HF1and 530.1 TCU3 HF1. The affected Experion PKS products are

C300 PCNT02, EHB, EHPM, ELMM, Classic ENIM, ETN, FIM4, FIM8, PGM, and RFIM. The Experion PKS versions affected are from 520.1 through 520.2 TCU9 and from 530 through 530 TCU3.

ICSA-25-205-03 — Honeywell Experion PKS (Update A)

The Honeywell Experion PKS contains an uninitialized variable in the common Epic Platform Analyzer (EPA) communications. An attacker could potentially exploit this vulnerability, leading to communication channel manipulation, which results in a dereferencing of an uninitialized pointer leading to a denial of service. The Honeywell Experion PKS contains a memory buffer vulnerability in the component Control Data Access (CDA). An attacker could potentially exploit this vulnerability, leading to overread buffers, which could result in improper index validation against buffer borders, leading to remote code execution. The Honeywell Experion PKS contains sensitive information in resource vulnerability in the component Control Data Access (CDA). An attacker could potentially exploit this vulnerability, leading to communication channel manipulation, which could result in buffer reuse, which may cause incorrect system behavior. The Honeywell Experion PKS contains an integer underflow vulnerability in the component Control Data Access (CDA). An attacker could potentially exploit this vulnerability, leading to communication channel manipulation, which could result in a failure during subtraction, allowing remote code execution. The Honeywell Experion PKS 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…
