CVE-2024-47617

Injection of arbitrary HTML/JavaScript code through the media download URL

Workarounds

Until an official patch is released, users can implement additional input validation and output encoding for the 'slug' parameter in the MediaStreamController's downloadAction method. Alternatively, configuring a Web Application Firewall (WAF) to filter potentially malicious input could serve as a temporary mitigation.

This vulnerability allows an attacker to inject arbitrary HTML/JavaScript code through the media download URL in Sulu CMS. It affects the SuluMediaBundle component. The vulnerability is a Reflected Cross-Site Scripting (XSS) issue, which could potentially allow attackers to steal sensitive information, manipulate the website's content, or perform actions on behalf of the victim.

Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

CVE-2024-47617 has a CVSS score of 6.1 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.6.5, 2.5.21); upgrading removes the vulnerable code path.

1. What is CVE-2024-47617? CVE-2024-47617 is a medium-severity cross-site scripting (XSS) vulnerability in sulu/sulu (composer), affecting versions >= 2.6.0, <= 2.6.4. It is fixed in 2.6.5, 2.5.21. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
2. How severe is CVE-2024-47617? CVE-2024-47617 has a CVSS score of 6.1 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of sulu/sulu are affected by CVE-2024-47617? sulu/sulu (composer) versions >= 2.6.0, <= 2.6.4 is affected.
4. Is there a fix for CVE-2024-47617? Yes. CVE-2024-47617 is fixed in 2.6.5, 2.5.21. Upgrade to this version or later.
5. Is CVE-2024-47617 exploitable, and should I be worried? Whether CVE-2024-47617 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2024-47617 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2024-47617?
   • Upgrade sulu/sulu to 2.6.5 or later
   • Upgrade sulu/sulu to 2.5.21 or later
