MantisBT: Stored XSS in print_all_bug_page_word.php

A missing output encoding call in print_all_bug_page_word.php allows any authenticated user to inject arbitrary HTML into an IMG tag's *alt* attribute via an image attachment with a crafted filename such as probe." onload="alert(1).

When any user views the HTML export page (print_all_bug_page_word.php?type_page=html&export=1), the rendered IMG tag becomes ``, breaking out of the alt attribute.

Impact

Cross-site scripting.
