CVE-2021-36336Network attack vector

Unauthenticated code execution via unsafe deserialization

Published Dec 21, 2021 · Updated Sep 16, 2024

Deserialization in Dell Wyse Management Suite 3.3.1 and earlier allows remote attackers to execute code without authentication. Dell has not disclosed the affected component, serialized input, or code path that processes the untrusted object data. Exposure requires network reachability to the affected WMS service; no credentials or user interaction are required.
