Does this mean that the application is definitely vulnerable? Is there a way to detect a version?

I don't think this parameters needs to be stored as datastore, you can use fixed delay probably

This adds an exploit module for Peyara Remote Mouse v1.0.1 unauthenticated RCE.
The module connects to the Socket.IO WebSocket service on TCP port 1313 and sends unauthenticated keyboard events to open cmd.exe and execute a Windows command payload.
