The security threat involves a stored Cross-Site Scripting (XSS) vulnerability identified as CVE-2025-10370 in RPi-Jukebox-RFID version 2.8.0, an open-source music player software designed for Raspberry Pi devices. The vulnerability exists in the userScripts.php page, specifically in the 'customScript' parameter, which fails to properly sanitize or encode user-supplied input. This flaw allows an attacker to inject malicious JavaScript code that is stored on the server and executed in the context of any user who accesses the affected page. The exploit demonstrates that an attacker can send a specially crafted POST request containing a payload that triggers a JavaScript alert, proving the ability to execute arbitrary scripts. The exploit code is implemented in Python, leveraging the 'requests' library to automate the injection of the payload. Since the vulnerability is stored XSS, it poses a persistent threat, enabling attackers to perform actions such as session hijacking, defacement, or delivering further malware to users interacting with the web interface. The vulnerability does not require authentication, making it accessible to any attacker with network access to the device's web interface. Although no active exploitation in the wild has been reported, the availability of public exploit code increases the risk of opportunistic attacks. The lack of official patches or mitigation guidance at the time of disclosure necessitates immediate attention from users of this software. The threat primarily targets devices running Raspberry Pi OS with RPi-Jukebox-RFID 2.8.0 installed, which are often used in home or small business environments for media playback.

For European organizations, the impact of this stored XSS vulnerability can range from moderate to significant depending on the deployment context. Organizations using RPi-Jukebox-RFID in shared or publicly accessible environments risk attackers injecting malicious scripts that execute in the browsers of legitimate users, potentially leading to session hijacking, theft of sensitive information, or unauthorized actions performed on behalf of users. While the software is niche and primarily used on Raspberry Pi devices, its presence in educational institutions, small businesses, or hobbyist environments within Europe could expose users to client-side compromise. The vulnerability could also be leveraged as a foothold for lateral movement or to deliver additional payloads within a network. Given the ease of exploitation without authentication and the availability of exploit code, attackers could quickly weaponize this vulnerability. However, the overall impact on large enterprises may be limited unless RPi-Jukebox-RFID is integrated into critical workflows or exposed to untrusted networks. The threat also raises privacy concerns under GDPR if personal data is compromised through session hijacking or credential theft. The absence of known active exploitation reduces immediate risk but does not eliminate the potential for future attacks.

1. Immediately upgrade RPi-Jukebox-RFID to a version where this vulnerability is patched once available. Monitor the official GitHub repository and vendor announcements for updates. 2. If patching is not immediately possible, restrict network access to the RPi-Jukebox-RFID web interface using firewall rules or VPNs to limit exposure to trusted users only. 3. Implement web application firewall (WAF) rules that detect and block suspicious input patterns targeting the 'customScript' parameter. 4. Educate users to avoid clicking on suspicious links or executing untrusted scripts within the RPi-Jukebox-RFID interface. 5. Regularly audit and sanitize any user-generated content or scripts stored in the application to remove malicious payloads. 6. Employ Content Security Policy (CSP) headers on the web server hosting the application to restrict the execution of inline scripts and reduce XSS impact. 7. Monitor logs for unusual POST requests to userScripts.php and anomalous user behavior indicative of exploitation attempts. 8. Consider isolating Raspberry Pi devices running this software in segmented network zones to minimize lateral movement risk. 9. Backup configuration and user data regularly to enable recovery in case of compromise. 10. Follow secure coding best practices for any custom scripts or extensions added to the platform.
