CVE-2024-29013Network attack vector

Authenticated firewall crash via SSL-VPN heap overflow

Published Jun 20, 2024 · Updated Mar 25, 2025

A heap-based buffer overflow in SonicWall SonicOS 7.1.1-7051 and earlier allows remote authenticated users to crash the firewall. The SSL-VPN component copies attacker-controlled data with memcpy without enforcing the destination heap buffer's bounds. A valid SSL-VPN account and a high-complexity request sequence are required; successful exploitation interrupts firewall availability.
