Denial Of Service (DoS)

pocketmine/pocketmine-mp is vulnerable to a Denial of Service DoS. The vulnerability exists due to the lack of default limits in the explode function, allowing malicious clients to abuse packets and exhaust server resources...

GHSA-G274-C6JJ-H78P PocketMine-MP allows malicious client data to waste server resources due to lack of limits for explode()

Impact Due to lack of limits by default in the explode function, malicious clients were able to abuse some packets to waste server CPU and memory. This is similar to a previous security issue published in https://github.com/pmmp/PocketMine-MP/security/advisories/GHSA-gj94-v4p9-w672, but with a...

Allocation of Resources Without Limits or Throttling

Overview pocketmine/pocketmine-mp is a highly customisable, open source server software for Minecraft: Bedrock Edition written in PHP Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the explode function. An attacker can occupy excessive...

Denial Of Service (DOS)

pocketmine/pocketmine-mp is vulnerable to Denial Of Service. The vulnerability is due to a lack of bounds checking when accessing inventory slots while calling function BaseInventory-getItem. This leads to an unhandled exception and potentially leads to Denial of service via malformed...

PocketMine-MP server crash with certain invalid JSON payloads in `LoginPacket` due to dependency vulnerability (3rd time)

Impact An attacker could crash PocketMine-MP by sending malformed JSON in LoginPacket. netresearch/jsonmapper allows objects to be hydrated from scalar types in JSON. However, due to the lack of validation in the code for this feature, it may output improperly initialized objects if applied to...

GHSA-H6J3-J35F-V2X7 PocketMine-MP server crash with certain invalid JSON payloads in `LoginPacket` due to dependency vulnerability (3rd time)

Impact An attacker could crash PocketMine-MP by sending malformed JSON in LoginPacket. netresearch/jsonmapper allows objects to be hydrated from scalar types in JSON. However, due to the lack of validation in the code for this feature, it may output improperly initialized objects if applied to...

PocketMine-MP BookEditPacket crash when inventory slot in the packet is invalid

Summary If a client sends a BookEditPacket with InventorySlot greater than 35, the server will crash due to an unhandled exception thrown by BaseInventory-getItem. Details Crashes at...

Name of the Vulnerable Software and Affected Versions: PocketMine-MP versions prior to 5.11.2 Description: The issue occurs when a client sends a BookEditPacket with an InventorySlot greater than 35, causing the server to crash due to an unhandled exception thrown by BaseInventory-getItem. This...

Denial Of Service (DOS)

pocketmine/raklib is vulnerable to Denial Of Service DOS. The vulnerability is caused by a missing validation on an upper bound for the maximum number of messages/packets that can be stored inside reliable-ordered queue until the data in the queue is ordered. A malicious client can exploit above...

pocketmine/raklib reliable-ordered queue size is unlimited, allowing a session to hog server memory

Impact A client can send reliable-ordered packets 0, 2, 3, 4, 5 ... etc, and all the packets 2 and up will stay in the reliable-ordered queue until 1 arrives. A malicious client can exploit this to waste all available server memory by simply never sending the missing packet. Since the server...

GHSA-W98G-5FMX-WM4X pocketmine/raklib reliable-ordered queue size is unlimited, allowing a session to hog server memory

Impact A client can send reliable-ordered packets 0, 2, 3, 4, 5 ... etc, and all the packets 2 and up will stay in the reliable-ordered queue until 1 arrives. A malicious client can exploit this to waste all available server memory by simply never sending the missing packet. Since the server...

PocketMine-MP server crash with certain invalid JSON payloads in `LoginPacket` due to dependency vulnerability (again)

Impact An attacker could crash PocketMine-MP by sending malformed JSON in LoginPacket. This happened due to the particular handling of NULL types in the json mapper which accepts NULL type values in typed arrays which PocketMine-MP did not expect. Code processing arrays in the JSON data could the...

GHSA-79RC-JJH6-RC89 PocketMine-MP server crash due to incorrect EC curve used for LoginPacket identityPublicKey

Impact The server uses ECDH to calculate a shared secret for the symmetric encryption key used to encrypt network packets after logging in. ECDH requires that the keys used must both belong to the same elliptic curve. In Minecraft: Bedrock Edition, the curve used is secp384r1. Using any other cur...
