Description
The disclosed vulnerability allows a remote user to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in the Layout module's administration page, when processing data passed via the "_com_liferay_layout_admin_web_portlet_GroupPagesPortlet_name" parameter (Site page name). A remote user can permanently inject 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.
