## Overview

kkFileView v5.0.0 through v5.0.2 contains a directory traversal vulnerability in FileController.java. The fileUpload, createFolder and existsFile endpoints accept a "path" parameter that is concatenated into the upload base path without validation, allowing unauthenticated attackers to create arbitrary directories and write arbitrary files outside the intended fileDir root via a crafted multipart request
