WampServer is a Windows web development environment. It allows you to create web applications with Apache2, PHP and a MySQL database.
WampServer is vulnerable to cross-site scripting vulnerability. This issue is due to the application's failure to properly sanitize user-supplied input thru the 'lang' parameter (GET) in index.php script. An attacker may leverage any of the cross-site scripting issues to have arbitrary script code executed in the browser of an unsuspecting user in the context of the affected site. This may facilitate the theft of cookie-based authentication credentials, phishing as well as other attacks.
