CVE-2022-39833Public exploitNetwork attack vector

Remote code execution via network-share path rewrite

Published Nov 23, 2022 · Updated Apr 25, 2025

Code injection in FileCloud 20.2 and later allows remote authenticated users to execute code through a crafted network-share request. The network-share editor accepts a local web-root path as a mount target, exposing application files to an assigned user who can upload a PHP shell. Administrator access is required to create and alter the share; the resulting access permits reading, modifying, or deleting server files and running uploaded code.
