Improper Validation of Certificate with Host Mismatch in Java-WebSocket

概要

Improper Validation of Certificate with Host Mismatch in Java-WebSocket

原文の説明

取得元が公開している説明をそのまま載せています (多くは英語)。

The Java-WebSocket Client does not perform hostname verification.

  • This means that SSL certificates of other hosts are accepted as long as they are trusted. To exploit this vulnerability an attacker has to perform a man-in-the-middle (MITM) attack between a Java application using the Java-WebSocket Client and an WebSocket server it's connecting to.
  • TLS normally protects users and systems against MITM attacks, it cannot if certificates from other trusted hosts are accepted by the client.
