Internet Explorer 6 on Windows XP SP2 allows remote attackers to execute arbitrary JavaScript in the context of the browser's session with an arbitrary intranet web server, by hosting script on an Internet web server that can be made inaccessible by the attacker and that has a domain name under the attacker's control, which can force the browser to drop DNS pinning and perform a new DNS query for the domain name after the script is already running.

Internet Explorer 6.0, and possibly other versions, allows remote attackers to bypass the same origin security policy and make requests outside of the intended domain by calling open on an XMLHttpRequest object (Microsoft.XMLHTTP) and using tab, newline, and carriage return characters within the first argument (method name), which is supported by some proxy servers that convert tabs to spaces. NOTE: this issue can be leveraged to conduct referer spoofing, HTTP Request Smuggling, and other attacks.
