Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
GFI MailEssentials AI versions prior to 22.4 contain a stored cross-site scripting vulnerability in the Local Domains settings page. An authenticated user can supply HTML/JavaScript in the ctl00$ContentPlaceHolder1$Pv3$txtDescription parameter to /MailEssentials/pages/MailSecurity/general.aspx, which is stored and later rendered in the management interface, allowing script execution in the context of a logged-in user.
