WebsitePanel - 'ReturnUrl' Open Redirection
source: https://www.securityfocus.com/bid/54346/info
WebsitePanel is prone to a URI-redirection vulnerability because the application fails to properly sanitize user-supplied input.
A successful exploit may aid in phishing attacks; other attacks are possible.
WebsitePanel versions prior to 1.2.2.1 are vulnerable.
