Description

The comment editing template (dzz/comment/template/edit_form.htm) in DzzOffice 2.3.x lacks adequate security escaping for user-controllable data in multiple contexts, including HTML and JavaScript strings. This allows low-privilege attackers to construct comment content or request parameters and execute arbitrary JavaScript code when the victim opens the editing pop-up.
