CVE-2025-6453Public exploitNetwork attack vector

Authenticated arbitrary file write via unchecked dirName

Published Jun 22, 2025 · Updated Jun 23, 2025

Path traversal in diyhi 巡云轻论坛 6.8 allows remote authenticated users to write uploaded images and lock files outside intended directories. The ForumManageAction.add path passes the unchecked dirName value into image-directory and lock-file path construction before creating directories and writing files. Administrative authentication, a valid layout ID, and a collection module are required; exploitation writes image data and a lock file to traversal-selected paths.
