CVE-2022-28620Network attack vector

Unauthenticated access to controller functions

Published Jun 24, 2022 · Updated Aug 3, 2024

Authentication bypass in HPE Cray EX, Legacy Shasta, and Slingshot controller firmware allows remote attackers to access protected functions. HPE identifies the affected loci as node, chassis, and switch controllers but has not published the faulty authentication operation. No credentials or user interaction are required over the network; the public bulletin does not identify which protected functions become available.
