CVE-2024-12802

Published Jan 9, 2025

Last updated 2 months ago

Overview

Description
SSL-VPN MFA Bypass in SonicWALL SSL-VPN can arise in specific cases due to the separate handling of UPN (User Principal Name) and SAM (Security Account Manager) account names when integrated with Microsoft Active Directory, allowing MFA to be configured independently for each login method and potentially enabling attackers to bypass MFA by exploiting the alternative account name.
