Baade M2M-Products GmbH: ubusd heap buffer overflow vulnerability in OpenWRT prior to version 24.10.4

Published Apr 2, 2026 · Updated Apr 2, 2026

Vendor: Baade M2M-Products Product: 1xCOM since 2018 Product: 4xCOM Product: Baade Linux

Summary

OpenWrt Project is a Linux operating system targeting embedded devices. Prior to version 24.10.4, ubusd contains a heap buffer overflow in the event registration parsing code. This allows an attacker to modify the head and potentially execute arbitrary code in the context of the ubus daemon. The affected code is executed before running the ACL checks, all ubus clients are able to send such messages. In addition to the heap corruption, the crafted subscription also results in a bypass of the listen ACL.

Details

Impact
ubus clients could exploit this vulnerability, resulting in a potential execution of arbitrary code.

Remediation
Baade M2M-Products GmbH recommends to upgrade the Baade Linux OS version of our Products TCP/IP-Web-Connector 1xCOM (since 2018) and TCP/IP-Web-Connector 4xCOM to version 4.65 or later to fix the ubusd security vulnerability.

Product Description
The field devices from Baade M2M-Products GmbH are industrial gateways shipped with a modified version of OpenWrt Linux.

Mitigation
Upgrade OpenWrt to 24.10.4 or later.
