SonicWall Patches Chained Zero-Day Vulnerabilities in SMA 1000 Series VPNs SonicWall has patched two zero-day vulnerabilities (CVE-2026-83548 and CVE-2026-83549) in its SMA 1000 series VPN appliances that attackers are chaining to achieve unauthenticated remote code execution. **If you run SonicWall SMA 1000 appliances (models 6210, 7210, or 8200v), update immediately to version 12.4.3-03526 or 12.5.0-02952. These devices are actively attacked to take over VPN gateways. After patching review your logs for signs of compromise, if anything looks suspicious, re-image the appliance, change all passwords and reset TOTP tokens, and only restore backups from before the breach.** #cybersecurity #infosec #advisory #vulnerability https://beyondmachines.net/event_details/sonicwall-patches-chained-zero-day-vulnerabilities-in-sma-1000-series-vpns-k-n-b-f-y/gD2P6Ple2L
