CVE-2022-30315: Honeywell Experion PKS Safety Manager (SM and FSC) through 2022-05-06 has Insufficient Verification of Data Authenticity.

Honeywell Experion PKS Safety Manager (SM and FSC) through 2022-05-06 has Insufficient Verification of Data Authenticity.

Honeywell Experion PKS Safety Manager (SM and FSC) through 2022-05-06 has Insufficient Verification of Data Authenticity. According to FSCT-2022-0053, there is a Honeywell Experion PKS Safety Manager insufficient logic security controls issue. The affected components are characterized as: Honeywell FSC runtime (FSC-CPU, QPP), Honeywell Safety Builder. The potential impact is: Remote Code Execution, Denial of Service. The Honeywell Experion PKS Safety Manager family of safety controllers utilize the unauthenticated Safety Builder protocol (FSCT-2022-0051) for engineering purposes, including downloading projects and control logic to the controller. Control logic is downloaded to the controller on a block-by-block basis. The logic that is downloaded consists of FLD code compiled to native machine code for the CPU module (which applies to both the Safety Manager and FSC families). Since this logic does not seem to be cryptographically authenticated, it allows an attacker capable of triggering a logic download to execute arbitrary machine code on the controller's CPU module in the context of the runtime. While the researchers could not verify this in detail, the researchers believe that

What it means for a small business

If your business uses Safety Manager Firmware, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.99%, higher than 62% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 28, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
