CVE-2022-51008
MediumCVSS 5.3Summary
PocketMine-MP before 4.12.3 fails to limit unauthenticated sessions, allowing attackers to exhaust player slots by creating sessions without sending LoginPacket. Attackers can flood the server with unauthenticated connections that occupy max-player slots, preventing legitimate players from joining.
Risk Assessment
The risk is the possibility of a DoS attack that prevents legitimate players from joining the server, potentially leading to service disruption.
Recommendation
Upgrade PocketMine-MP to version 4.12.3 or later, which includes the fix to limit unauthenticated sessions.
Other vulnerabilities in PocketMine-MP
See all- CVE-2022-51009High
PocketMine-MP before 4.7.2 fails to properly handle exceptions from the adhocore/json-comment library when parsing skin geometry data. Attackers can send login or skin packets with invalid geometry JSON to trigger an unhandled RuntimeException, causing server crash.
- CVE-2021-48007Medium
PocketMine-MP versions before 3.18.1 fail to validate NaN or INF values in MovePlayerPacket position and rotation fields. Malicious clients can send crafted movement packets with invalid floating-point values to crash servers through unhandled mathematical operations or prevent clients from rendering other players.
- CVE-2021-48006Low
PocketMine-MP before 4.0.3 does not perform case-insensitive matching when removing operator entries from ops.txt. The removeOp function lowercases the supplied name but only removes an exactly matching entry, so an operator name stored with non-lowercase letters cannot be revoked using the deop command, leaving the player as an operator until the entry is removed from ops.txt manually.
- CVE-2020-37277Medium
PocketMine-MP versions before 3.15.4 contain a denial of service vulnerability in the InventoryTransaction component's findResultItem() method. Malicious clients can send specially crafted InventoryTransactionPackets with multiple conflicting pathways to cause exponential processing complexity, freezing the server.
- CVE-2023-7332High
PocketMine-MP versions prior to 4.18.1 have an improper input validation vulnerability in inventory transaction handling. A remote attacker with a valid player session can request dropping more items than available in the hotbar, causing a server crash and denial of service.
