Remote code execution via management-interface command injection
Published Sep 4, 2026 · Updated Sep 4, 2026
OS command injection in SonicWall Network Security Manager 4.3.0 and earlier allows remote authenticated users to execute host commands. The on-premises management interface passes attacker-controlled input into operating-system command execution without neutralizing command elements. Exploitation requires SuperAdmin privileges and results in arbitrary command execution on the underlying host.
