Description

The vulnerability allows a remote user to execute arbitrary JavaScript in the browser of another user and perform actions in the context of the victim's session.

The vulnerability exists due to stored cross-site scripting in the HTML index page for hosted repository directory browsing when rendering uploaded content. A remote user can upload crafted content to a hosted repository to execute arbitrary JavaScript in the browser of another user and perform actions in the context of the victim's session.

User interaction is required, as a separate user must browse the repository contents via the built-in HTML index page.


Remediation

Install security update from vendor's website.
