Improper authentication in Necta LLC WiFi Mouse (Mouse Server) 1.8.2.3 and 1.8.3.4 allows remote attackers to execute code. The server treats its needpassword response as a client-side prompt yet continues accepting openfile, UTF-8 character, and Return commands without verifying the PIN. Any host able to reach TCP port 1978 can open the Windows command shell and type commands with the privileges of the Mouse Server process.
