CVE-2022-30242
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 configuration changes from remote users. This enables configuration data to be stored on the controller and then implemented. A user with malicious intent can send a crafted packet to change the controller configuration without the knowledge of other users, altering the controller's function capabilities. The changed configuration is not updated in the User Interface, which creates an inconsistency between the configuration display and the actual configuration on the controller. After the configuration change, remediation requires reverting to the correct configuration, requiring either physical or remote access depending on the configuration that was altered.
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 for remote configuration changes, allowing unauthenticated attackers to send crafted packets that modify controller settings. The modified configuration persists on the controller but does not update in the UI, creating a discrepancy between displayed and actual settings.

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.
-
Confirm product identityIdentify if the device in question is a Honeywell Alerton Ascent Control Module (ACM) by checking the device label, web interface, or management console for the model nameAffected if The device is confirmed to be a Honeywell Alerton Ascent Control Module
-
Check firmware versionAccess the ACM web interface or management console and locate the firmware version information, typically found in System Info, About, or Diagnostics sectionsAffected if Firmware version is dated 2022-05-04 or earlier, or the version string indicates a date on or before May 4, 2022
-
Verify network exposure of configuration interfaceExamine network configuration and firewall rules to determine if the ACM remote configuration port (commonly ports 80/443 or vendor-specified ports) is accessible from untrusted or external networksAffected if The configuration interface is reachable from untrusted networks without network segmentation or access controls
-
Compare UI configuration against actual settingsAccess the ACM web interface to view current configuration settings, then use out-of-band methods (direct console access, backup configuration file, or third-party monitoring tool) to retrieve the actual running configuration and compare the twoAffected if There is a discrepancy between configuration values displayed in the web UI and the actual running configuration on the device
-
Review network logs for unauthorized config changesCheck ACM system logs, network firewall logs, or intrusion detection systems for suspicious packets or configuration change events originating from unauthenticated or unexpected IP addressesAffected if Logs show configuration change requests from unknown or unauthenticated sources
A user is affected if they have a Honeywell Alerton Ascent Control Module with firmware dated May 4, 2022 or earlier that has its configuration interface accessible from untrusted networks, or if configuration discrepancies exist between the UI and actual device settings.

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.
dbcve · scopedImplement authentication for all remote configuration interfaces and consider network segmentation to limit exposure of the ACM to untrusted networks; verify configuration integrity through out-of-band methods.
