CVE-2023-32752Network attack vector

Unauthenticated command execution via unrestricted file upload

Published Jun 16, 2023 · Updated Dec 11, 2024

Unrestricted file upload in L7 Networks InstantScan IS-8000 and InstantQoS IQ-8000 allows remote attackers to execute system commands. The web interface upload function accepts dangerous executable file types without validation and permits uploaded files to run on the appliance. No authentication or user interaction is required; successful exploitation grants command execution and can interrupt appliance service.
