Detailed vulnerability description

The vulnerability allows a remote attacker to perform phishing attacks.

The weakness exists due to improper validation of user-supplied data used to redirect visitors to external pages. A remote attacker can create a specially crafted link, trick the victim into following it, spoof the URL displayed to redirect a user to a malicious Web site that would appear to be trusted and obtain potentially sensitive information.

Successful exploitation of the vulnerability will allow to steal valid user's credentials and use the information to conduct further attacks.
