Bugzilla contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate various fields when embedded in the header tags (e.g., <h1></h1>). This could allow a user to create a specially crafted URL 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.
