CVE-2020-4193Network attack vector

Credential brute force via inadequate account lockout

Published Jun 4, 2020 · Updated Sep 17, 2024

Inadequate account lockout in IBM Security Guardium 11.1 allows remote attackers to brute-force account credentials. The appliance's account-lockout configuration permits excessive failed authentication attempts instead of disabling the targeted account. Exploitation requires network access to a Guardium authentication endpoint and enough guesses to recover a valid credential; the disclosed consequence is credential compromise.
