CVE-2026-111548

MediumCVSS 5.3
Published: Updated: Translated: NVD NIST

Summary

A stack-based buffer overflow vulnerability exists in the web management interface of affected Moxa wireless device servers. An authenticated remote attacker with low privileges could exploit insufficient bounds checking of user-supplied input, causing the web management service to become unresponsive; restoring the service requires power cycling the device while other functions remain operational.

Risk Assessment

An attacker can cause unavailability of the management interface, hindering device administration. This requires a physical or remote restart, potentially causing operational disruptions.

Recommendation

Update Moxa device firmware to a version containing the fix. Restrict access to the web management interface to trusted networks and least-privilege accounts.
