An unauthenticated, remote attacker who can convince a user to take a malicious action, could perform a XSS attack on the user. The vulnerability exists due to mishandling of certain attributes that are processed within cookies passed as part of a request. A successful exploit may allow the attacker to execute arbitrary script or HTML code on the user's browser within the context of the affected site.
