Patch Version: Version 2.7.1 or later
Vendor Advisory: https://github.com/MiczFlor/RPi-Jukebox-RFID/issues/2396
Restart Required: Yes
Instructions:
1. Backup your configuration and data. 2. Update to version 2.7.1 or later via git pull or fresh installation. 3. Restart the web server and jukebox services. 4. Verify the inc.setWlanIpMail.php file has been patched.
🔧 Temporary Workarounds
Remove vulnerable file
linuxDelete or rename the vulnerable PHP file to prevent exploitation
sudo rm /var/www/html/htdocs/inc.setWlanIpMail.php
Restrict web access
linuxConfigure firewall to block external access to the web interface

- Disable the web interface entirely and use only local controls
🔍 How to Verify
Check if Vulnerable:
Check if file /var/www/html/htdocs/inc.setWlanIpMail.php exists and contains user input being passed to system() or exec() functions without proper sanitization.Check Version:
cd /home/pi/RPi-Jukebox-RFID && git log --oneline -1Verify Fix Applied:
Verify the file has been updated in version 2.7.1+ or removed. Check that user input is properly validated before being used in system calls.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to inc.setWlanIpMail.php
- Suspicious system commands in web server logs
- Unexpected process execution from web server user
Network Indicators:
- Unusual outbound connections from the Raspberry Pi
- Traffic to known malicious IPs or domains
SIEM Query:
source="web_server_logs" AND uri="*inc.setWlanIpMail.php*" AND (method="POST" OR status="200")
