CVE-2022-31228Network attack vector

Admin access via unrestricted password guessing

Published Oct 12, 2022 · Updated May 15, 2025

Improper authentication-attempt restriction in Dell XtremIO XMS before 6.4.0-22 allows remote attackers to gain admin access. The SSH and Web UI authentication paths do not adequately restrict repeated password guesses against an administrator account. No credentials are required, but successful exploitation depends on completing the high-complexity guessing attack and grants administrative control.
