"The Microsoft Project Server installation on the remote host is missing a security update. It is, therefore, affected 
by a cross-site-scripting (XSS) vulnerability. Microsoft SharePoint Server does not properly sanitize a specially
crafted web request to an affected SharePoint server. An authenticated attacker could exploit the vulnerability by
sending a specially crafted request to an affected SharePoint server. The attacker who successfully exploited the
vulnerability could then perform cross-site scripting attacks on affected systems and run scripts in the security
context of the current user. The attacks could allow the attacker to read content that the attacker is not authorized to
read, use the victim's identity to take actions on the SharePoint site on behalf of the user, such as change permissions
and delete content, and inject malicious content in the browser of the user.");
