Moxa NPort W2150A / W2250A wireless device server: A remote attacker can crash or potentially gain code execution
Impact
A remote attacker can crash or potentially gain code execution on the device server by sending a crafted payload to its web management service — the built-in web server has a stack-based buffer overflow.
Who can reach it
Remote, over the network — no authentication mentioned as a prerequisite in the vendor advisory; reachability to the web service is sufficient to trigger the overflow.
What to do
Firmware upgrade to the version in Moxa's MPSA-238975 advisory. Flash and reboot each unit; serial sessions on that device drop briefly during the update.
