CVE-2022-38650Network attack vector

Unauthenticated code execution via insecure deserialization

Published Nov 12, 2022 · Updated Aug 3, 2024

Insecure deserialization in VMware Hyperic Server 5.8.6 allows remote attackers to execute arbitrary code through network requests. Public sources do not identify the receiving endpoint, serialized object format, or deserialization routine that processes attacker-controlled data. No authentication is required, and successful exploitation runs code in the server and host operating system with the Hyperic server process privileges.
