CVE-2022-3228

Device crash via oversized configuration fields

Published Oct 28, 2022 · Updated Apr 16, 2025

A stack-based buffer overflow in Host Engineering H0-ECOM100 firmware 5.0.155 and earlier allows remote attackers to crash the module. Custom requests can write name or description values beyond fixed-size stack buffers because the firmware does not enforce destination bounds. Unauthenticated access from an adjacent network is sufficient; the documented consequence is a crash or unresponsive device.
