Authenticated arbitrary file write via filename traversal
Published Apr 30, 2026 · Updated Apr 30, 2026
Path traversal in Shopizer 3.2.5 and earlier allows remote authenticated users to write arbitrary files through a crafted image upload. The image-upload controller accepts traversal sequences in qqfilename, and CmsStaticContentFileManagerImpl appends that value to a storage path before Files.copy writes it without normalization or a root-boundary check. Exploitation requires an admin or merchant JWT and the httpd storage backend; a JSP placed in static content can execute commands as the application process.
