CVE-2016-15017Network attack vector

Server file access via unsanitized upload filenames

Published Jan 10, 2023 · Updated Aug 6, 2024

Path traversal in Media Upload for TYPO3 CMS before 0.9.0 allows remote authenticated users to access server files via crafted names. The getUploadedFiles method appends filenames from getUploadedFileList to UploadManager::UPLOAD_FOLDER without removing parent-directory sequences before checking and returning the resulting paths. Frontend authentication is required by default but can be disabled through configuration, and consuming code can import reached files into TYPO3 resource storage.
