Username enumeration via distinct login failure responses
Published Sep 18, 2024 · Updated Sep 25, 2024
Observable response discrepancy in Mautic 5.1.0 allows remote attackers to enumerate usernames through failed login requests. The login flow returns a weak-password notification for an existing username but an invalid-credentials response for a nonexistent one. A candidate username and an incorrect weak password are required; the disclosure confirms only whether that account name exists.
