Administrator RCE via arbitrary file upload
Published Jul 23, 2025 · Updated Jul 25, 2025
Arbitrary file upload in SonicWall SMA 100 Series 10.2.1.15-81sv and earlier allows remote authenticated users to execute arbitrary code. The vendor has not disclosed the affected upload handler or exact validation failure; public records state only that the web management interface accepts arbitrary files. Exploitation requires administrative privileges and permits attacker-chosen files to reach the appliance, with code execution as the bounded consequence.
