Vulnerability Description

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).

Recommended Actions

1. Maintain the observed Atomicorp protections. Keep your Atomicorp commercial rules current and confirm that the selected observed rules (344361 , 344363 ) have not been locally disabled. Atomicorp commercial rules are enabled by default. If you use Atomic WAF, review the applicable policy and rule settings.

2. Apply the vendor’s remediation. WAF protection is defense in depth and does not replace upgrading or following the affected vendor’s guidance.

   • Affected versions: Honeywell PM23/43 versions earlier than P10.19.050004.
   • Affected versions: Honeywell PC23/43, PD43 versions earlier than K10.19.050004.
   • Affected versions: Honeywell PM42 versions earlier than T10.19.050004.
   • Affected versions: Honeywell PM42 versions earlier than L10.19.050004.
   • Affected versions: Honeywell PX4ie/6ie versions earlier than A10.19.050004.
   • Affected versions: Honeywell PX45/65 versions earlier than B10.19.050004.
   • Affected versions: Honeywell PD45, PX240 versions earlier than F10.19.050004.
   • Affected versions: Honeywell PX940 versions earlier than H10.19.050004.
   • Affected versions: Honeywell PM45 versions earlier than J10.19.050004.
   • Affected versions: Honeywell RP2f/RP4f versions earlier than M10.19.050006.
   • No specific CNA/vendor solution or workaround is included in the current CVE Record (opens in a new tab) . Review the vendor’s security advisories and supported-release guidance before making changes.

3. Validate after changes. Confirm rule updates are current, review WAF events for the affected application, and test application behavior after vendor upgrades, mitigations, or local policy changes.

Research Notes

Atomicorp WAF protections are designed around attack techniques and exploit behaviors, allowing existing protections to apply across multiple vulnerabilities without requiring a unique rule for every CVE.

Research Note Context

This research note documents exploit-technique analysis associated with this vulnerability and references Atomicorp WAF protections observed during engineering review, testing, or validation activities.

Atomicorp security controls are generally designed to identify and mitigate attack techniques and exploit behaviors rather than individual CVE identifiers. As a result, protections developed for one vulnerability may also apply to related attack variants and future vulnerabilities using similar techniques.
