Popen is the underlying class for the whole subprocess module. All functions in the subprocess module are convenience wrappers around the Popen() constructor and its instance methods. Near the end of this tutorial, you’ll dive into the Popen class. Note: If you’re trying to decide whether ...
RCE的两种方法前面长篇大论已经提到了一些,这里再整理一下:一种是在object.__subclasses__()中找到os模块中的类(一般是<class 'os._wrap_close'>),另一种是先拿到__builtins__,再__import__('os').system('sh')。 RCE的payload模板可以通过chrome中hackbar插件SSTI的Show subclasses with tuple拿到; ...
