CVE-2022-51015 pmmp CVE debrief

Who should care

Defenders responsible for PocketMine-MP servers should assess exposure and prioritize verification and remediation efforts to prevent potential server crashes and instability. Server administrators and security teams should verify server versions, prioritize packet data validation, and consider remediation to mitigate the risk of denial of service via crafted packets. Defenders should care about CVE-2022-51015 because it allows a remote authenticated

Why it matters

Defenders should care about CVE-2022-51015 because it allows a remote authenticated attacker to crash PocketMine-MP servers before version 4.0.6, resulting in a denial of service. Server administrators and security teams should assess exposure, prioritize verification of server versions and packet data validation, and consider remediation.

• Denial of service via crafted packets
• Potential for server crashes and instability
• Need for validation and verification of packet data

Technical summary

PocketMine-MP before 4.0.6 does not validate facing values in PlayerActionPacket or UseItemTransactionData, allowing a remote authenticated attacker to send crafted packets and crash the server, resulting in a denial of service. The vulnerability arises from the server's failure to validate facing values, which can be exploited by an attacker to cause server crashes and instability. Defenders should prioritize verifying server versions and validating packet data to prevent potential server crashes and instability. Server administrators and security teams should assess exposure, prioritize verification of server versions and packet data validation, and consider remediation to mitigate the risk of denial of

Defensive priority

Defenders should prioritize verifying server versions and validating packet data.

Recommended defensive actions

• Verify PocketMine-MP server versions and upgrade to 4.0.6 or later
• Validate packet data to prevent crafted packets from crashing the server
• Monitor server logs for suspicious activity
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes
