Specifically, Wicket's DiskFileItem class, serialized by Kryo, allows an attacker to hack its serialized form to put a client on an infinite loop if the client attempts to write on the DeferredFileOutputStream attribute. Mitigation: Upgrade to Apache Wicket 6.25.0 or 1.5.17 Credit: This issue was discovered by Jacob Baines, Tenable Network Security and Pedro Santos References: https://wicket.apache.org/news
