CVE-2024-37019Network attack vector

Cross-tenant account takeover via duplicate SAML users

Published Jun 3, 2024 · Updated Feb 13, 2025

Weak authentication in Northern.tech Mender Enterprise before 3.6.4 and 3.7.0 through 3.7.3 allows remote authenticated users to take over accounts. The backend authentication code accepts duplicate identities created through an attacker-controlled external SAML service and associates them with existing password-based users in other tenants. Exploitation requires privileged access to configure or manage SAML and a multi-tenant deployment; successful abuse crosses tenant, RBAC, password, and TOTP boundaries.
