CVE-2026-10829
Moxa NPort Stack-Based Buffer Overflow Remote Code Execution
Description

A stack-based buffer overflow vulnerability has been found in the NPort W2150A-W4/W2250A-W4 Series version 1.5 and earlier. This vulnerability stems from insufficient input validation of user-supplied input in the "Server location" parameter on the Basic settings page. An attacker could exploit this vulnerability by sending crafted input to the web service, resulting in memory corruption. Successful exploitation of this vulnerability could allow remote code execution on the target system with root privileges.
