Certain Mozilla products contain a cross-site scripting vulnerability because of a vulnerability in the XPCNativeWrapper function.
Per Mozilla, XPCNativeWrapper is a way to wrap up an object so that it is safe to access from privileged code. It is used to allow chrome code to access DOM objects.
By convincing a victim to view an HTML document (web page), an attacker could evaluate script in a different security domain than the one containing the attacker's document. The attacker could read or modify data in other web sites (read cookies/content, modify/create content, etc.). If the script is evaluated with chrome privileges, an attacker could execute arbitrary commands on the user's system.
Thanks to Mozilla for reporting this vulnerability. Mozilla in turn thanks shutdown.
