A file inclusion vulnerability exists in the confd.exe module in Honeywell Experion PKS R40x before R400.6, R41x before R410.6, and R43x before R430.2, which could lead to accepting an arbitrary file into the function, and potential information disclosure or remote code execution. Honeywell strongly encourages and recommends all customers running unsupported versions of EKPS prior to R400 to upgrade to a supported version.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
