CVE-2024-13022Public exploitNetwork attack vector

Authenticated arbitrary file upload via missing validation

Published Dec 29, 2024 · Updated Dec 30, 2024

Unrestricted file upload in Taisan AI Tarzan CMS 1.0.0 allows remote authenticated users to store arbitrary files via the upload endpoint. UploadController.upload passes the multipart file to OssService.upload, which rejects only null input and stores all other content without validating its type. Access to the article-management backend is required; successful exploitation writes attacker-chosen files to the server.
