MailOrderWorks contains a flaw that allows a persistent cross-site scripting (XSS) attack. This flaw exists because the application does not validate the 'Reason/fault', 'Resolution', 'Issue Notes', and 'Order notes' fields upon submission to the Create/View issues. This may allow an attacker to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
