CVE-2022-37936Network attack vector

Unauthenticated object injection via Java deserialization

Published Feb 22, 2023 · Updated Mar 17, 2025

Deserialization of untrusted data in HPE Serviceguard Manager before A.12.80.05 allows remote attackers to inject Java objects via network requests. Serviceguard Manager accepts serialized Java objects from unauthenticated requests without sufficient trust validation; HPE has not disclosed the affected endpoint or class. No credentials or user interaction are required, while HPE leaves the available post-deserialization actions unspecified.
