CVE-2022-39023Network attack vector

Authenticated system-file disclosure via Download path traversal

Published Oct 31, 2022 · Updated May 6, 2025

Path traversal in U-Office Force 20.50.7821D Build:202104sp1 and earlier allows remote authenticated users to read arbitrary system files. The Download function fails to confine a supplied pathname to its intended directory and returns the file resolved outside that boundary. General user privileges and network access to the application are required; the published impact is file disclosure, not modification or service interruption.
