Deserialization Vulnerability in Apache OpenMeetings by The Apache Software Foundation

CVE-2024-54676

Summary

A deserialization vulnerability in Apache OpenMeetings due to inadequate clustering instructions can lead to potential exploitation. The default setup does not detail blacklists or whitelists for OpenJPA, allowing attackers to manipulate the deserialization process and potentially execute malicious code. Users are strongly advised to upgrade to version 8.0.0 and adjust startup scripts to implement the appropriate 'openjpa.serialization.class.blacklist' and 'openjpa.serialization.class.whitelist' settings. This precaution is crucial for maintaining the security of the application against unauthorized data handling.
