Dedecms breaks user registration restrictions

When we are engaged in dede, we always find that we cannot register, so some vulnerabilities cannot be used. What if the website prohibits registration of new members? There are two ways to break through: Method 1: Modify the registration submit page source code, change the form action value to "http://www.yesck.com/member/reg_new.php? _ POST [pai_mb_allowreg] = Y ". Method 2: Modify the source code of the registration submission page and add the "input" element to the form. The name attribute is "COOKIE [mongomballowreg]" and the value is "Y" (not "N ").
