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
Session Fixation vulnerability in Honeywell PM43 on 32 bit, ARM (Printer web page modules) allows Session Credential Falsification through Prediction.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

Session Fixation vulnerability in Honeywell PM43 industrial printers (32-bit ARM web page modules) allows attackers to predict or manipulate session credentials, enabling unauthorized access to the printer web interface. The vulnerability stems from predictable session identifiers that can be forged or fixed by an attacker before victim authentication.

MitigationUpdate Honeywell PM43 firmware to version P10.19.050006 (MR19.5) or later to replace vulnerable session management with properly randomized session identifiers.

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 Honeywell PM43 printer on the network
    Access the printer web interface or use network scanning tools to confirm the device model is Honeywell PM43 (32-bit ARM version). Check the device's web page for model identification or use SNMP/network discovery to retrieve the device identifier.
    Affected if The device is a Honeywell PM43 industrial printer with web interface enabled.
  2. Check the installed firmware version
    Log into the printer web interface and navigate to the 'About' or 'Status' page to view the firmware version. Alternatively, access the printer via SNMP or the front panel menu to retrieve the firmware build number.
    Affected if The firmware version is earlier than p10.19.050004 (e.g., p10.19.xxxxxx where the build is below 050004, or any version with 'p10' prefix below 10.19.050004).
  3. Verify the web server module is enabled
    Confirm that the embedded web server (EWS) or web page modules are enabled on the printer. This can be done by attempting to access the printer's IP address on HTTP/HTTPS ports (typically 80/443) or by checking the printer's network configuration settings for web interface status.
    Affected if The web interface is accessible and enabled, exposing the session management to network attackers.
  4. Inspect session identifier behavior
    Observe the session cookies or session IDs generated by the printer web interface. Access the login page multiple times from the same client IP and compare the session identifiers provided before authentication. Look for patterns, predictable increments, or static values across different sessions.
    Affected if Session identifiers appear predictable, follow a sequential pattern, or remain fixed across different authentication attempts from the same client.

The printer is affected if it is a Honeywell PM43 with web interface enabled and firmware version earlier than p10.19.050004, particularly if session IDs show predictable patterns.

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 replace vulnerable session management with properly randomized session identifiers.

Recommended fix High confidence

P10.19.050006 (or later/MR19.5)

  1. Download the latest PM43 firmware (P10.19.050006 or later/MR19.5) from Honeywell's support portal or FTP server (hsmftp.honeywell.com)
  2. Transfer the firmware file to the printer via USB, Ethernet, or the printer's web interface
  3. Access the PM43 printer web interface or control panel
  4. Navigate to the firmware update or system maintenance section
  5. Select the downloaded firmware file and initiate the update process
  6. Wait for the firmware update to complete and the printer to restart automatically
  7. Verify the firmware version has been updated to P10.19.050006 or later in the printer's web interface or control panel
Caveat Firmware updates may temporarily interrupt printer operations; verify compatibility with any custom print workflows before deploying broadly
