MantisBT: Stored XSS in print_all_bug_page_word.php
The advisory, in context
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 <img src="..." alt="" onload="alert(1)" />, breaking out of the alt attribute.
Impact
Cross-site scripting.
Impact is limited by MantisBT's Content Security Policy.
