Description
PocketMine-MP versions before 5.25.2 fail to limit the explode() function in packet parsing, allowing malicious clients to waste server resources. Attackers can send crafted packets with excessive delimiters to consume CPU and memory through sign editing, JWT parsing, and command parsing endpoints.

AI Analysis

Impact

PocketMine-MP versions before 5.25.2 allow an attacker to send packets containing an excessive number of delimiters, causing the server to call the explode() function without limits. This produces high CPU and memory consumption during sign editing, JWT parsing, and command parsing, ultimately leading to a service disruption. The weakness is classified as *CWE‑400 Uncontrolled Resource Consumption* and manifests as a denial of service.

Affected Systems

The vulnerability affects all PocketMine‑MP installations running a version earlier than 5.25.2. No additional version qualifiers are listed, so any build prior to that release is potentially impacted.

Risk and Exploitability

The CVSS score of 6.9 indicates a medium severity risk; the EPSS score is not available, and the flaw is not listed in the CISA KEV catalog. Attackers can exploit the flaw by connecting to the PocketMine‑MP server over the network and sending specially crafted packets, so the vector is inferred to be remote network traffic. No public exploit code has been reported, but the lack of input validation makes the vector straightforward for automated attacks that trigger resource exhaustion.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade PocketMine‑MP to version 5.25.2 or later, which includes patch that limits input to explode().
  • If an upgrade cannot be performed immediately, restrict inbound connections to the PocketMine‑MP server by firewall rules or by placing the server behind a VPN so that only trusted clients can reach it.
  • Monitor server CPU and memory usage for sudden spikes and implement automated measures to terminate or reset connections from clients that send unusually large packets.
