CVE-2024-10127Network attack vector

Unauthenticated login via anonymous LDAP bind

Published Nov 20, 2024 · Updated Feb 23, 2026

Authentication bypass in M-Files Server before 24.11 allows remote attackers to log in without a password through LDAP. The LDAP authentication path treats a successful anonymous bind as proof of user authentication instead of rejecting a missing password. Exploitation requires LDAP authentication and an OpenLDAP server configured to permit anonymous binding, which is not enabled by default.
