CVE-2023-46172Network attack vector

Unauthenticated access bypass via undisclosed HMC flaw

Published Mar 7, 2024 · Updated Aug 2, 2024

Improper authentication in the IBM DS8900F HMC allows remote attackers to bypass restrictions on authorized-user access. IBM has not disclosed the affected HMC request path, authentication check, or operation that mishandles unauthenticated input. No credentials or user interaction are required, but attack complexity is high; IBM states that affected HMC log files contain no customer data and external users cannot access customer data.
