Description
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 affected device, while other device functions remain operational.
