VULNERABILITY DESCRIPTION:
==========================
The scripts "/common/pages/lib/footer_login.php" and 
"/common/pages/lib/footer_loggedin.php" are prone to a cross-site-scripting 
vulnerability because they fail to properly sanitize user-supplied input in the 
"msg" parameter.

An attacker may leverage this issue to execute arbitrary script code in the 
browser of an unsuspecting user in the context of the affected site. This may 
help the attacker steal cookie-based authentication credentials and launch 
other attacks.
