Title: WampServer <= 2.2c (lang) Remote Cross-Site Scripting Vulnerability
Advisory ID: ZSL-2012-5072
Type: Remote
Impact: Cross-Site Scripting
Risk: (3/5)
Release Date: 17.02.2012

Summary

WampServer is a Windows web development environment. It allows you to create web applications with Apache2, PHP and a MySQL database.

Description

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.
