Here's yet another patch for an exploit being abused in csgo to lag/dos servers within the last few weeks. This patch affectively just disables rcon from working. The real way to solve the issue and maintain rcon for sourcebans or admins would be to firewall off all ips to the tcp port of your game server except ones you whitelist. However many cheap hosts don't give access to firewall options along with not giving clients the ability to just never set an rcon_password. Setting rcon_password "" inside your server.cfg (and never setting it anywhere else) will prevent rcon from working and will solve the issue with the exploit.

This patch should only be used if you have no way to access the firewall and you can't not set the rcon_password convar.
THIS WILL BREAK SOURCEBANS AND OTHER SOFTWARE THAT COMMUNICATES WITH YOUR SERVER VIA RCON PROTOCOL
