Detailed vulnerability description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
