Feature:
With a modified client (the version of the client I found is private) that spams the opening of a book that contains a lot of characters in json, it is possible to crash any server in version 1.8. Beyond that, it seems that spigot has fixed this breach.
This plugin uses NMS to force the player to be kicked if his modified client does not disconnect when he is kicked. It is therefore currently only available for the 1.8.8 for the moment.
[FOR DEVELOPPER] If you want to help me make a reflection of NetworkManager & PlayerConnection to close the player's login channel, please contact me privately.
You have a config.yml to change the message of the kick.
I would not share the modified client. This plugin is based on the RoweFix plugin presented here . RoweFix is not optimized at all and has bugs. That's why FixCrashBook was born.
If you have any suggestions, do not hesitate to give them to me here .
- Fix a server crash that can be done with a modified client by kick the player & cancel the packet.
Spoiler: What happens when a player tries to crash your server?
