CVE-2025-8937Network attack vector

Authenticated command injection via formSysCmd handler

Published Aug 14, 2025 · Updated Aug 15, 2025

Command injection in TOTOLINK N350R 1.2.3-B20130826 allows remote authenticated users to execute commands via /boafrm/formSysCmd. The public record identifies the request handler but does not disclose the attacker-controlled parameter or the operation that passes its value to a command interpreter. Access to the router management interface and valid low-privilege credentials are required; successful exploitation runs commands with the handler's privileges and can alter data or interrupt service.
