- Summary
- PocketMine-MP vulnerable to denial-of-service by sending large modal form responses
- Details
-
Impact
Due to a workaround for an old client bug (which has since been fixed), very large JSON payloads in
ModalFormResponsePacketwere able to cause the server to spend a significant amount of time processing the packet. Large numbers of these packets were able to hog CPU time so as to prevent the server from processing other connections in a timely manner.Patches
The problem has been addressed in 3baa5ab71214f96e6e7ab12cb9beef08118473b5 by removing the workaround code.
Workarounds
Plugins could cancel
DataPacketReceiveEventfor this packet, decode the data their way, and then callPlayer->onFormSubmit()directly, bypassing the vulnerable code. - Database specific
