CVE-2024-12802Network attack vector

MFA bypass via alternate Active Directory name

Published Jan 9, 2025 · Updated May 22, 2026

Authentication bypass in SonicWall SonicOS SSL-VPN allows remote authenticated users to access the VPN without completing MFA. The SSL-VPN authentication path treats an Active Directory account's UPN and SAM name as separate identities, so MFA can cover one login form but not the other. Exposure requires valid account credentials, Active Directory integration with an additional UPN suffix, and an SSLVPN User Domain configuration that leaves the alternate login form outside MFA.
