CVE-2025-66260

6.5 MEDIUM

📋 TL;DR

This SQL injection vulnerability in DB Electronica Telecomunicazioni's Mozart FM Transmitter allows attackers to execute arbitrary SQL queries via the status_sql.php endpoint. Attackers can exfiltrate database contents and perform reconnaissance through verbose error messages. All Mozart FM Transmitter versions 30 through 7000 are affected.

💻 Affected Systems

Products:
  • DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter
Versions: Versions 30, 50, 100, 300, 500, 1000, 2000, 3000, 3500, 6000, 7000
Operating Systems: Unknown - Likely embedded Linux systems
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the web interface component status_sql.php which is likely accessible via HTTP/HTTPS.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise including sensitive configuration data, user credentials, and system information exfiltration leading to full system takeover.

🟠

Likely Case

Data exfiltration from PostgreSQL database including configuration details, potentially leading to further system compromise.

🟢

If Mitigated

Limited information disclosure through error messages if input validation is partially implemented.

🌐 Internet-Facing: HIGH - The vulnerable endpoint is web-accessible and requires no authentication.
🏢 Internal Only: MEDIUM - Internal attackers could exploit this to escalate privileges or exfiltrate sensitive data.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation is straightforward as no authentication is required and the vulnerability is in a web endpoint with direct SQL injection via GET/POST parameters.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: Unknown

Restart Required: No

Instructions:

No official patch available. Implement workarounds or contact vendor for updated firmware.

🔧 Temporary Workarounds

Web Application Firewall (WAF)

all

Deploy a WAF with SQL injection rules to block malicious requests to status_sql.php

Network Access Control

linux

Restrict access to the Mozart FM Transmitter web interface to trusted IP addresses only

iptables -A INPUT -p tcp --dport 80 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP

🧯 If You Can't Patch

  • Disable or block access to the status_sql.php endpoint at the network level
  • Implement strict input validation and parameterized queries if source code modification is possible

🔍 How to Verify

Check if Vulnerable:

Send a test request to /status_sql.php with SQL injection payload in sw1 or sw2 parameters and check for database errors or unexpected responses

Check Version:

Check web interface or device management console for firmware version information

Verify Fix Applied:

Test with SQL injection payloads after implementing fixes - successful fix should return generic error or no data leakage

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL error messages in web server logs
  • Multiple requests to status_sql.php with SQL keywords in parameters
  • Requests containing UNION, SELECT, or other SQL injection patterns

Network Indicators:

  • HTTP requests to /status_sql.php with SQL syntax in parameters
  • Unusual database query patterns from web server IP

SIEM Query:

source="web_logs" AND uri="/status_sql.php" AND (param="sw1" OR param="sw2") AND (content CONTAINS "UNION" OR content CONTAINS "SELECT" OR content CONTAINS "' OR '")
