Description

The remote web server contains a PHP application that is prone to cross-site scripting attacks.

Description :

According to its banner, the remote version of PunBB is vulnerable to cross-site scripting flaws because the application does not validate URL and quote tags. With a specially-crafted URL, an attacker may be able to inject arbitrary HTML and script code into a user's browser, resulting in a loss of integrity.
