Stack-based Buffer Overflow in Moxa NPort W2150A-W4/W2250A-W4 Web Interface
CVE-2026-10829 is a stack-based buffer overflow in the web service of Moxa NPort W2150A-W4 and W2250A-W4 Series devices running firmware version 1.5 and earlier. The flaw is caused by insufficient input validation of user-supplied data in the "Server location" parameter on the Basic settings page. By submitting crafted input to this parameter via the device web interface, an attacker can trigger memory corruption on the target system. Moxa indicates that successful exploitation may lead to remote code execution with root privileges.
