CMailServer contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate users' details (username, name, comments, etc.) which are displayed in admin.asp. This could allow a malicious user to create specially crafted user details via setpersoninfo.asp that would execute arbitrary code in the WebMail administrator's browser, leading to a loss of integrity.
