Description Adam Mariš 2015-09-07 13:53:31 UTC

Inside php_zip.c there's a function called php_zip_make_relative_path which is used to sanitize the file path when extracting a file/directory from a ZIP. When extracting a file, the sanitized pathname is used, so files are only created inside of the directory where they're being extracted. However, for directories, the unsanitized/user-provided "file" value is used instead of the sanitized "path_cleaned" value. As a result, a directory can be created outside of the directory where a ZIP file is being extracted.
