CVE-2022-22553Network attack vector

Account takeover via unrestricted password attempts

Published Jan 21, 2022 · Updated Sep 16, 2024

Improper login throttling in Dell EMC AppSync 3.9 through 4.3 allows remote attackers to brute-force passwords through the UI or CLI. Dell has not disclosed the implementation locus or how the UI and CLI authentication paths fail to restrict repeated attempts. No authentication is required, but account takeover depends on guessing a weak password; the published record establishes no takeover when passwords resist guessing.
