RPi-Jukebox-RFID 2.8.0 Vulnerable to Stored XSS Attack (CVE Pending)

Stored XSS Vulnerability Discovered in RPi-Jukebox-RFID 2.8.0

Security researchers have identified a stored cross-site scripting (XSS) vulnerability in RPi-Jukebox-RFID version 2.8.0, a popular open-source jukebox solution for Raspberry Pi. The flaw allows attackers to inject malicious scripts via specially crafted RFID tags, which are then executed when accessed by other users.

Technical Details

The vulnerability (currently without a CVE ID) stems from insufficient input sanitization in the RFID tag processing functionality. When a user scans a malicious RFID tag, the payload is stored in the application's database and later rendered in the web interface without proper escaping. This enables arbitrary JavaScript execution in the context of the victim's browser session.

Key technical aspects:

• Affected Component: RFID tag processing module
• Attack Vector: Malicious RFID tags with embedded JavaScript
• Impact: Session hijacking, credential theft, or unauthorized actions
• Exploitation Requirements: Physical or remote access to the RFID tag input system

Impact Analysis

The stored XSS vulnerability poses significant risks to RPi-Jukebox-RFID deployments, particularly in shared or public environments such as:

• Educational institutions using the system for media playback
• Community centers or libraries with public jukebox setups
• IoT enthusiasts running the software in home automation ecosystems

Successful exploitation could lead to:

• Session hijacking via stolen cookies or tokens
• Phishing attacks through fake login prompts
• Privilege escalation if administrative functions are exposed
• Lateral movement in networked environments

Recommendations

Security teams and administrators should take the following steps:

1. Apply Patches: Monitor the RPi-Jukebox-RFID GitHub repository for official fixes. No patch is currently available.
2. Input Validation: Implement strict input sanitization for all RFID tag data before processing or storage.
3. Content Security Policy (CSP): Deploy CSP headers to mitigate XSS impact by restricting script execution sources.
4. Network Segmentation: Isolate RPi-Jukebox-RFID instances from critical internal networks to limit potential lateral movement.
5. User Awareness: Train users to recognize suspicious activity, such as unexpected pop-ups or login prompts.
