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 · unedited
Improper Input Validation vulnerability in Honeywell PM43 on 32 bit, ARM (Printer web page modules) allows Command Injection.This issue affects PM43 versions prior to P10.19.050004. Update to the latest available firmware version of the respective printers to version MR19.5 (e.g. P10.19.050006).

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 confidence

Improper input validation in the web page modules of Honeywell PM43 printers (32-bit ARM versions) allows remote attackers to inject and execute arbitrary operating system commands. This critical vulnerability stems from insufficient sanitization of user input in the printer's web interface, enabling complete compromise of the affected device.

MitigationUpdate Honeywell PM43 firmware to version P10.19.050006 (MR19.5) or later to remediate the command injection vulnerability. Prioritize external-facing printers given the critical severity.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the printer model
    Access the printer's web interface or physical display to confirm the model is Honeywell PM43 (32-bit ARM version). The 32-bit ARM versions are specifically affected by this vulnerability.
    Affected if The device is a Honeywell PM43 printer running on a 32-bit ARM processor.
  2. Determine the installed firmware version
    Log into the printer's web interface and navigate to the Settings or About section to view the firmware version. Alternatively, print a configuration or status page from the printer's control panel to retrieve the firmware build number.
    Affected if The firmware version is lower than p10.19.050004.
  3. Verify the web interface is accessible
    Attempt to access the printer's web interface by entering the printer's IP address in a web browser. Confirm the login page or status page loads successfully.
    Affected if The web interface is enabled and reachable on the network.
  4. Confirm web page modules are enabled
    Check the printer's network configuration or web server settings to verify that the embedded web server and its page modules are turned on. This is typically found under Network Settings or Web Server options in the printer's administration panel.
    Affected if The web page modules are enabled on the device.

If the device is a Honeywell PM43 (32-bit ARM) with firmware version below p10.19.050004 and the web interface with its page modules is enabled, the environment is affected by CVE-2023-3710.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update Honeywell PM43 firmware to version P10.19.050006 (MR19.5) or later to remediate the command injection vulnerability. Prioritize external-facing printers given the critical severity.

Recommended fix Moderate confidence

P10.19.050006 (MR19.5 release)

  1. Download the latest PM43 firmware version P10.19.050006 (or later MR19.5 release) from Honeywell's support portal at hsmftp.honeywell.com or www.honeywell.com
  2. Access the PM43 printer web management interface or use the printer's firmware update mechanism
  3. Upload and apply the firmware update to the PM43 printer
  4. Verify the firmware version has been updated to P10.19.050004 or later
