Summary

Moxa NPort W2150A-W4/W2250A-W4 Series wireless device servers from 1.0 through 1.5 contain a stack-based buffer overflow (CWE-121) in the web management interface. Insufficient bounds checking of user-supplied input lets an authenticated remote attacker with low privileges make the web management service unresponsive. Restoring the service requires power cycling the device, while other device functions keep running.
