The Site Editor (SiteBuilder) feature for Parallels Plesk Small Business Panel contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate input passed via the 'file' parameter or an arbitrary request parameter upon submission to the /Wizard/Edit/Modules/Image script. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
