CVE-2025-7627Public exploitNetwork attack vector

Remote code execution via traversal-based template upload

Published Jul 14, 2025 · Updated Jul 14, 2025

Unrestricted file upload in YiJiuSmile kkFileViewOfficeEdit allows remote attackers to execute arbitrary system commands. FileController.fileUpload accepts a multipart filename containing parent-directory sequences and writes the file outside its intended directory, allowing web/index.ftl to be replaced with an attacker-controlled FreeMarker template. No authentication or user interaction is required; requesting the replaced index template executes its embedded operating-system command with the service's privileges.
