Title: Microsoft Internet Explorer Multimedia Page Cross-Site Scripting Vulnerability
Severity: MODERATE
Description:
Microsoft Internet Explorer is prone to cross-site scripting attacks.
When a multimedia file is loaded by MSIE (such as a Macromedia SWF file), instead of loading the file directly, a separate page is generated which contains the URI of the file. HTML tags and script code are not filtered when the URI is displayed in this separate page. As a result, an attacker may create a malicious link which contains arbitrary script code. If a user of the vulnerable web browser visits such a link, the attacker-supplied script code will be interpreted by their browser. This will occur in the context of the website the link points to. An attacker may obfuscate this malicious link so that it seems innocuous.
An attacker may exploit this issue to steal cookie-based authentication credentials from web users. Other attacks are also possible.
