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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
