Name of the Vulnerable Software and Affected Versions: PocketMine-MP versions prior to 4.23.1 PocketMine-MP versions prior to 5.3.1 Description: An attacker could crash PocketMine-MP by sending malformed JSON in the LoginPacket. This issue occurred due to the handling of NULL types in the json...

Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to Denial Of Service DoS. The vulnerability exists in due to the netresearch/jsonmapper dependency due to improper mappings of JSON arrays and objects onto scalar model properties which allows an attacker to send malformed JWT JSON in the LoginPacket causing...

Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to Denial Of Service DoS. The vulnerability exists due to improperly checked dropped item count which allows players to request that the server drop more of an item than they had available in their hotbar causing an application crash...

pocketmine/pocketmine-mp is vulnerable to Denial Of Service DoS. The vulnerability exists due to missing rate-limits which allows an attacker to consume resources via mismatched type of a InventoryTransactionPacket which results in an application crash...

GHSA-7WRV-6H42-W54F PocketMine-MP vulnerable to server crash using badly formatted sign NBT in BlockActorDataPacket

Summary A player sending a packet can cause the server to crash by providing incorrect sign data in NBT in BlockActorDataPacket. Details This vulnerability was discovered using the BlockActorDataPacket, but other packets may also be affected. The player would seem to just need to send an NBT with...

PocketMine-MP vulnerable to improperly checked dropped item count leading to server crash

Impact In 4.18.0, the network handling of inventories was completely revamped. Due to this, a bug was introduced which allowed players to request that the server drop more of an item than they had available in their hotbar. This did not lead to any duplication issues, but instead led to a server...

PocketMine MP vulnerable to uncontrolled resource consumption via mismatched type of 'InventoryTransactionPacket'

Impact A "mismatch" type InventoryTransactionPacket is sent by the client to request a resync of all currently open inventories. Since PocketMine-MP does not rate-limit these "mismatch" transactions, and the syncing of inventories is not deferred until, e.g. the end of the current tick, they can ...

Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to Denial of Service DoS. The vulnerability due to large modal form responses which causes the server to spend a significant amount of time processing the packet leading to an application crash...

PocketMine-MP vulnerable to denial-of-service by sending large modal form responses

Impact Due to a workaround for an old client bug which has since been fixed, very large JSON payloads in ModalFormResponsePacket were 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...

PocketMine-MP has improperly handled dye colour IDs in banner NBT, leading to server crash

Impact DyeColorIdMap-fromId did not account for the possibility that it might be given invalid input. This means that an undefined offset error would occur whenever this happened. This code is indirectly called during Banner-deserializeCompoundTag, which is invoked when deserializing any item NBT...
