[ali.of.south () keemail me]

Hello,

Sails.js (https://sailsjs.com/) <https://sailsjs.com/> before v1.0.0-46 allows attackers to cause a denial of service 
with a single request because there is no error handler in sails-hook-sockets to handle an empty pathname in a 
WebSocket request.
[Affected Product Code Base]
Sails.js - < v1.0.0-46
sails-hook-sockets - < 1.5.5

[Attack Vectors]
To exploit vulnerability, attacker should make a request with malformed URL to the socket.

[Reproducing]
1. generate a default sails app.
2. sails lift
3. open app in the browser.
4. open the browser console.
5. execute this code: io.socket.get('?').
