CyberRota Analysis
AI-GeneratedThe Sulu content management system is vulnerable to an attack that allows an authenticated user with media upload permissions to exploit the inline query parameter in specific routes, potentially serving malicious HTML or XML content. This could lead to cross-site scripting (XSS) attacks, where attacker-controlled JavaScript executes within the context of the victim's session, compromising user data and actions. Organizations using affected versions should prioritize updating to versions 2.6.25 or 3.0.8 to mitigate this risk.

Original NVD Description
Sulu is an open-source PHP content management system based on the Symfony framework. 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'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.
