What is CVE-2024-12802?

A vulnerability in SonicWALL’s SSL-VPN could allow attackers to bypass Multi-Factor Authentication (MFA) by exploiting inconsistencies in how User Principal Names (UPN) and Security Account Manager (SAM) account names are handled during integration with Microsoft Active Directory. This separation enables attackers to configure MFA independently for different login methods, creating a potential pathway for unauthorized access.
