| Title | lsFusion 6.1 Unauthorized Arbitrary File Read |
|---|
| Description | The API /file/static/noauth/** is used to download logos and icons without authentication. The handleRequest method in DownloadFileRequestHandler supports a version parameter. While the /** path component is validated, if an attacker directly accesses /file/static/noauth (without a trailing path), the filename is derived solely from the unvalidated version parameter. The generated fileName is then directly appended to FileUtils.APP_DOWNLOAD_FOLDER_PATH, leading to arbitrary file read vulnerabilities. |
