CVE-2022-23671

Privileged actions via exposed cluster communications

Published May 17, 2022 · Updated Aug 3, 2024

Information disclosure in ClearPass Policy Manager 6.10.4 and earlier allows attackers to read sensitive cluster communications. The flaw is in cluster communications, but HPE has not disclosed the protocol, message type, or operation that exposes the data. Reachability requires a privileged position on the cluster network; exposed information enables unauthorized privileged actions on the cluster.
