Prior to versions 2.6.25 and 3.0.8, src/Sulu/Bundle/MediaBundle/Controller/MediaStreamController.php allows the /media/{id}/download/{slug} route and its administration variant to honor the inline query parameter for scriptable MIME types. The vulnerable stored Content-Type values include text/html, application/xhtml+xml, text/xml, and application/xml. An attacker with media upload permission can store an HTML, XHTML, or XML document and create a link using inline=1, causing the application to return the file on the Sulu origin instead of forcing Content-Disposition attachment. When an authenticated victim opens the link, attacker-controlled JavaScript can execute with the victim&#39;s Sulu-origin session and can read data or perform actions as that victim. This issue is fixed in versions 2.6.25 and 3.0.8.</p> <p>Sulu is an open-source PHP content management system based on the Symfony framework.

When it is present, the response is sent with the header `Content-Disposition: inline` for any MIME type, which overrides the disposition rules the server would otherwise apply. By default, HTML and other scriptable uploads are not blocked, the file is served on the application origin with its stored `Content-Type`, and no `X-Content-Type-Options` or `Content-Security-Policy` header is sent. Because of this, an attacker can upload an HTML file and build a link that runs their own JavaScript in the context of the Sulu origin.</p> <p>Every installation where users who are not fully trusted can upload media is affected. This includes editors who hold the media add permission. Such an editor can store a payload that runs in the authenticated session of anyone who opens the link, including an administrator, which allows theft of the session and credentials and lets the attacker act as the victim.</p> <p>The problem is present on the 2.6 and 3.0 branches and goes back to the introduction of the `?inline` override in 2017.
