CVE-2019-19810Public exploitNetwork attack vector

Unauthenticated code execution via crafted RMI requests

Published Oct 28, 2021 · Updated Aug 5, 2024

Java deserialization in Eleveo Zoom Call Recording 6.3.1 allows remote attackers to execute arbitrary code through its RMI service. The service deserializes attacker-controlled objects passed as remote-method arguments, enabling direct object insertion or argument-type-safety bypasses around JEP 290 filtering. No authentication or user interaction is required; successful exploitation runs attacker-selected code on the recording server.
