Lotus Notes contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate HTML attachments of emails upon displaying them to the user. In addition, Lotus Notes fails to properly sanitise the attachment's file name before displaying it to the user. Both these issues could allow an attacker to create a specially crafted HTML file or a specially crafted file name that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
