CVE-2022-30244
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHoneywell Alerton Ascent Control Module (ACM) through 2022-05-04 allows unauthenticated programming writes from remote users. This enables code to be store on the controller and then run without verification. A user with malicious intent can send a crafted packet to change and/or stop the program without the knowledge of other users, altering the controller's function. After the programming change, the program needs to be overwritten in order for the controller to restore its original operational function.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Honeywell Alerton Ascent Control Module (ACM) lacks authentication enforcement for remote programming write operations, allowing unauthenticated attackers to send crafted packets that can modify, inject, or stop control logic running on the controller without detection.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Honeywell Alerton Ascent Control Module on the networkLocate and confirm any Honeywell Alerton Ascent Control Module (ACM) devices on the network by reviewing asset inventories, network scans, or device documentationAffected if A Honeywell Alerton Ascent Control Module is present in the environment
-
Check the ACM firmware versionAccess the device management interface or use the vendor-provided tool to retrieve the installed firmware version, then compare it against the affected range of versions <= 2022-05-04Affected if The firmware version is 2022-05-04 or earlier
-
Verify remote programming interface exposureDetermine if the remote programming or configuration interface on the ACM is exposed to the network by reviewing firewall rules, access control lists, and network segmentation configurationsAffected if The remote programming interface is accessible from untrusted networks or unauthorized IP addresses
-
Inspect authentication configuration for programming operationsReview the ACM security settings to confirm whether authentication is enforced for remote programming or write operations; check if the device allows unauthenticated write access to control logicAffected if Authentication is not enforced or is bypassed for remote programming write operations
The environment is affected if a Honeywell Alerton Ascent Control Module with firmware version 2022-05-04 or earlier has its remote programming interface exposed without proper authentication enforcement.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataPrimary mitigations include network segmentation to isolate the control system from untrusted networks and implementing firewall rules to restrict access to authorized endpoints only; coordinate with Honeywell for firmware updates that address the authentication bypass.
