Unsanitized use of FileUpload filename
Overview
Rule ID:
java_lang_file_upload_filenameApplicable Languages: Java
Weakness ID: CWE-73
Description
Failure to sanitize filenames from FileUpload can result in path traversal attacks. This vulnerability arises when an attacker manipulates the filename to access files or directories located outside the designated directory.
Remediation Guidelines
Avoid using unsanitized filenames directly from FileUpload, as attackers can exploit them to navigate the server's directory structure.
Always sanitize user input when managing file paths. Utilize secure methods such as
FilenameUtils.getName()to ensure the path is protected and cannot be manipulated for directory traversal."
