CVE-2023-43042Network attack vector

Default superuser status disclosure via unauthenticated query

Published Dec 14, 2023 · Updated May 22, 2025

Information disclosure in IBM Storage Virtualize 8.3 allows remote attackers to determine whether the default superuser password was changed. An unauthenticated status query exposes the password-change state of the privileged superuser account; IBM has not published the request details. Practical exposure is limited to 8.3.1 systems that still retain the default password, and the disclosed fact does not itself reveal the password.
