Denial-of-service vulnerability processing large chat messages containing many newlines

Impact PocketMine-MP caps maximum chat message length at 512 Unicode characters, or about 2048 bytes. No more than 2 chat messages may be sent per tick. However, due to legacy reasons, incoming chat message blobs are split by \n, and each part is treated as a separate message, the length of each...

GHSA-G5RR-P69H-7V3G Insufficient type validation in pocketmine/pocketmine-mp

Impact When an inventory interaction is performed e.g. moving an item around an inventory, the client sends a serialized version of the itemstack to the server, which the server then deserializes and compares against its own copy. If the copies don't match, the transaction is invalid. This involv...

Buffer length underflow in LoginPacket causing unchecked exceptions to be thrown

Impact LoginPacket uses BinaryStream-getLInt to read the lengths of JSON payloads it wants to decode. Unfortunately, BinaryStream-getLInt returns a signed integer, meaning that a malicious client can craft a packet with a large uint32 value for payload buffer size which would be interpreted as a...

Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to denial of service. The vulnerability exists due to lack of validations in the file upload in the netItemStackToCore function of TypeConverter.php which allows an attacker to cause an application crash...

Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to denial of service. An attacker may exploit the vulnerability and crash the system by sending a maliciously crafted MovePlayerPacket to the server whose position or rotation contains NaN or INF...

NaN/INF in serverbound movement packets can crash clients and servers

Impact A malicious client may send a MovePlayerPacket to the server whose position or rotation contains NaN or INF. Since neither the server nor vanilla client handles this properly, a number of interesting side effects come into play. - The server may crash in various ways if this exploit is use...

GHSA-FM35-JGG3-3GRX NaN/INF in serverbound movement packets can crash clients and servers

Impact A malicious client may send a MovePlayerPacket to the server whose position or rotation contains NaN or INF. Since neither the server nor vanilla client handles this properly, a number of interesting side effects come into play. - The server may crash in various ways if this exploit is use...

Insecure Encryption

pocketmine/pocketmine-mp is using insecure encryption. The vulnerability exists in 'Minecraft Bedrock' function, due to authentication and protocol encryption are unchangeable servers are allowed to connect internet directly...

Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to denial of service. The vulnerability exists due to the unhandled exception in the stupidjsondecode function of InGamePacketHandler.php when decoding an invalid JSON response form, which allows an attacker to cause an application crash...

GHSA-H79X-98R2-G6QC Impersonation of other users (passing XBOX Live authentication) by theft of logins in PocketMine-MP

Impact Minecraft Bedrock authentication and its protocol encryption are inseparably linked. One is not complete without the other. This vulnerability affects servers which are able to be directly connected to via the internet i.e. not behind a proxy. If you are using a proxy, please check that it...

Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to denial of service. An attacker is able to send PlayerActionPacket with invalid facing values e.g. negative, specifically with STARTBREAK or CRACKBLOCK actions, or with a UseItemTransactionData typically in InventoryTransactionPacket, causing an applicatio...

Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to denial of service DoS. The vulnerability exists as the handleBookEdit class does not limit the size of pages and characters to be fill. which allows an attacker to cause an application crash...

Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to denial of service. The library does not properly validate byte limit in the skin length resulting in an overflow, allowing an attacker to crash the application...

Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to denial of service DoS. The vulnerability exists as InventoryTransactionPackets can be used to cause an exponential computation to occur through InventoryTransaction-findResultItem...
