CVE-2021-24171 – WooCommerce Upload Files < 59.4 - Unauthenticated Arbitrary File Upload

https://notcve.org/view.php?id=CVE-2021-24171

The WooCommerce Upload Files WordPress plugin before 59.4 ran a single sanitization pass to remove blocked extensions such as .php. It was possible to bypass this and upload a file with a PHP extension by embedding a "blocked" extension within another "blocked" extension in the "wcuf_file_name" parameter. It was also possible to perform a double extension attack and upload files to a different location via path traversal using the "wcuf_current_upload_session_id" parameter. El plugin de WordPress WooCommerce Upload Files versiones anteriores a 59.4 ejecutó una sola pasada de saneamiento para eliminar extensiones bloqueadas como .php.&#xa0;Era posible omitir esto y cargar un archivo con una extensión PHP insertando una extensión "blocked" dentro de otra extensión "blocked" en el parámetro "wcuf_file_name". • https://wpscan.com/vulnerability/ed4288a1-f7e4-455f-b765-5ac343f87194 https://www.wordfence.com/blog/2021/03/critical-vulnerability-patched-in-woocommerce-upload-files • CWE-434: Unrestricted Upload of File with Dangerous Type •
