CVE-2024-8330Network attack vector

Authenticated command execution via unrestricted file upload

Published Aug 30, 2024 · Updated Aug 30, 2024

Unrestricted file upload in Gether Technology 6SHR System allows remote authenticated users to execute arbitrary server commands via a web shell. The upload handler fails to validate file types and stores attacker-supplied web-shell scripts where the server can execute them. Regular application privileges are required, after which the uploaded script provides command execution with the server process's access.
