ReliaQuest has documented active in-the-wild exploitation of CVE-2024-12802, a SonicWall Gen6 SSL-VPN MFA bypass that hits Gen6 devices even after they apply the firmware patch. SonicWall's advisory makes clear that on Gen6 hardware, the firmware update alone does not fix it - administrators must also delete the LDAP configuration that uses userPrincipalName, remove cached LDAP users, drop the SSL VPN User Domain back to LocalDomain, reboot, and rebuild the LDAP config without userPrincipalName. Gen7 and Gen8 devices are patched by firmware alone. Intrusions observed between February and March 2026 looked like ransomware initial-access broker activity with 30-60 minute Cobalt Strike and BYOVD attempts.
SonicWall released emergency firmware updates for Gen 6, Gen 7, and Gen 8 firewalls after CrowdStrike's research team disclosed three SonicOS flaws on April 29. The worst is CVE-2026-0204 (CVSS 8.0), a weak authentication bug in the management interface that lets an attacker on an adjacent network reach management functions without logging in - and from there change firewall rules, disable security protections, or open new holes. The other two are post-authentication: CVE-2026-0205 is a path traversal that breaks out of restricted directories, and CVE-2026-0206 is a buffer overflow that crashes the firewall. No public exploits yet.
