      <title>CVE-2022-51016 — PocketMine-MP 3.x before 3.27.0 Authentication Bypass via Login Replay</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-51016</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; pmmp PocketMine-MP&lt;/p&gt;
&lt;p&gt;PocketMine-MP 3.x (before 3.27.0) does not implement Minecraft Bedrock protocol encryption, so the server cannot verify that a connecting client possesses the private key corresponding to its login token. An attacker who captures a valid login from another player&amp;#39;s session (for example by tricking the player into connecting to an attacker-controlled server) can replay that login to impersonate the victim and pass XBOX Live authentication until the JWT token expires (typically 2-3 days). This affects servers directly reachable over the internet that are not behind a proxy with encryption enabled. Fixed in 4.0.0 and backported to 3.27.0.&lt;/p&gt;</description>
