CVE-2022-51010

PocketMine-MP versions before 4.4.2 fail to properly validate item IDs received from clients in itemstack NBT data. Attackers can send crafted item IDs outside the valid range to trigger an uncaught exception that crashes the server.

What this means for your business

  • An attacker can use it remotely, over a network, with an ordinary user login, and without anyone at your company clicking anything.

What to do

  1. 1Ask your IT team or provider whether any of your systems use the affected product.
  2. 2If you do, follow the vendor's guidance. No patch reference has been published yet.
