Descriptions

In GetSimpleCMS 3.3.15, admin/upload.php blocks .html uploads but there are several alternative cases in which HTML can be executed, such as a file with no extension or an unrecognized extension (e.g., the test or test.asdf filename), because of admin/upload-uploadify.php, and validate_safe_file in admin/inc/security_functions.php.

En GetSimpleCMS 3.3.15, admin/upload.php bloquea las subidas de .html, pero hay varios casos alternativos en los que se puede ejecutar HTML, como con un archivo sin extensión o con una extensión desconocida (como, por ejemplo, los nombres de archivo test o test.asdf). Esto se debe a admin/upload-uploadify.php y a validate_safe_file en admin/inc/security_functions.php.
