CVE-2025-3987Public exploitNetwork attack vector

Authenticated command injection via localPin parameter

Published Apr 27, 2025 · Updated Apr 28, 2025

Command injection in TOTOLINK N150RT 3.4.0-B20190525 allows remote authenticated users to execute operating-system commands. The /boafrm/formWsc handler fails to neutralize shell metacharacters in the localPin form value before command processing. A valid administrative session is required, and successful exploitation permits arbitrary command execution on the router.
