CVE-2025-63951
📋 TL;DR
This CVE describes an insecure deserialization vulnerability in the MiczFlor RPi-Jukebox-RFID project's rss-mp3.php script. Remote unauthenticated attackers can inject arbitrary PHP objects via the 'rss' GET parameter, potentially causing denial of service or other impacts. Anyone using affected versions of this software is vulnerable.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, though this depends on available PHP classes and configuration
Likely Case
Denial of service through PHP errors or crashes, potentially disrupting the jukebox functionality
If Mitigated
No impact if proper input validation and deserialization controls are implemented
🎯 Exploit Status
Exploitation requires sending crafted serialized data to the vulnerable endpoint
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Commit after 4b2334f0ae0e87c0568876fc41c48c38aa9a7014
Vendor Advisory: https://github.com/solonbarroso/vulnerability-research/blob/main/advisories/RPi-Jukebox-RFID/CVE-2025-63951.md
Restart Required: No
Instructions:
1. Update to latest version from GitHub repository
2. Replace rss-mp3.php with patched version
3. Verify the fix implements proper input validation
🔧 Temporary Workarounds
Disable RSS-MP3 functionality
linuxRemove or disable access to the vulnerable rss-mp3.php script
sudo mv /path/to/rss-mp3.php /path/to/rss-mp3.php.disabled
Web server access control
linuxRestrict access to the script using web server configuration
# Add to Apache .htaccess:
<Files "rss-mp3.php">
Order deny,allow
Deny from all
</Files>
🧯 If You Can't Patch
- Implement network segmentation to isolate the vulnerable system
- Deploy a web application firewall (WAF) with deserialization attack detection
🔍 How to Verify
Check if Vulnerable:
Check if rss-mp3.php exists and contains unserialize() calls without validationCheck Version:
git log --oneline -1Verify Fix Applied:
Verify the patched version validates input before deserialization📡 Detection & Monitoring
Log Indicators:
- PHP unserialize errors
- Unusual POST/GET requests to rss-mp3.php
Network Indicators:
- HTTP requests with serialized data in 'rss' parameter
SIEM Query:
source="web_logs" AND uri="*rss-mp3.php*" AND (param="rss" OR data CONTAINS "O:")
