CVE-2022-24289Network attack vector

Authenticated code execution via Hessian deserialization

Published Feb 11, 2022 · Updated Aug 3, 2024

Deserialization of untrusted data in Apache Cayenne 4.1 and earlier allows remote authenticated users to execute arbitrary code. The ROPServlet accepts Hessian POST bodies and deserializes attacker-controlled objects, allowing gadget code in vulnerable server dependencies to run. Exploitation requires client access to optional ROP and a non-current Java patch level; the resulting code runs in the server process.
