CVE-2022-47186Network attack vector

Unauthenticated file upload and deletion via unrestricted directory

Published Sep 28, 2023 · Updated Sep 23, 2024

Unrestricted file upload in Generex CS141 before 2.06 allows remote attackers to upload or delete arbitrary files without authentication. The web interface's upload-directory handler accepts every file type and deletion request without authenticating the requester or enforcing a format allowlist. Network access to the device is sufficient; published evidence establishes arbitrary file creation and deletion but does not establish code execution.
