Title: Microsoft Internet Explorer Custom HTTP Error HTML Injection Vulnerability
Severity: HIGH
Description:
An issue has been reported for Microsoft Internet Explorer that may result in HTML injection attacks. The vulnerability exists when IE is used to display custom HTTP error messages also known as "Friendly HTTP error messages".
IE 5 and later include HTML resource files that are able to display the custom HTTP errors. A function in the HTML resource files is to extract the real URL from the document.
When an error occurs, IE will request the following resource:
res://shdoclc.dll/<HTTP STATUS CODE>_HTTP.htm#http://<URL>
Due to some errors when extracting the URL from the above requested resource, it is possible to cause IE to execute malicious HTML code.
Exploitation may allow theft of cookie-based authentication credentials or other attacks.
This vulnerability was reported to affect Microsoft Internet Explorer 6.0 SP1 and earlier. It is likely that other applications that use the IE engine are also vulnerable to this issue.
