CVE-2013-2745

9.8 CRITICAL

📋 TL;DR

CVE-2013-2745 is an SQL injection vulnerability in MiniDLNA media server software that allows attackers to execute arbitrary SQL commands. This affects MiniDLNA installations prior to version 1.1.0. Attackers can potentially read, modify, or delete database content.

💻 Affected Systems

Products:
  • MiniDLNA (aka ReadyMedia)
Versions: All versions prior to 1.1.0
Operating Systems: Linux, Unix-like systems, Embedded systems
Default Config Vulnerable: ⚠️ Yes
Notes: Affects all default installations of vulnerable versions. MiniDLNA is commonly used in NAS devices and media servers.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of the MiniDLNA server, potential data exfiltration, and possible remote code execution through SQL injection chaining.

🟠

Likely Case

Unauthorized access to media database, manipulation of media metadata, and potential denial of service.

🟢

If Mitigated

Limited impact with proper network segmentation and access controls, though SQL injection remains possible.

🌐 Internet-Facing: HIGH - MiniDLNA servers exposed to internet are directly vulnerable to SQL injection attacks.
🏢 Internal Only: MEDIUM - Internal attackers or compromised internal systems could exploit this vulnerability.

🎯 Exploit Status

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

SQL injection is well-documented and relatively easy to exploit. Public exploit details exist in security advisories.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.1.0 and later

Vendor Advisory: https://security-tracker.debian.org/tracker/CVE-2013-2745

Restart Required: Yes

Instructions:

1. Update MiniDLNA to version 1.1.0 or later. 2. For Debian/Ubuntu: sudo apt-get update && sudo apt-get install minidlna. 3. Restart MiniDLNA service: sudo systemctl restart minidlna

🔧 Temporary Workarounds

Network Segmentation

linux

Restrict MiniDLNA server access to trusted networks only

iptables -A INPUT -p tcp --dport 8200 -s TRUSTED_NETWORK -j ACCEPT
iptables -A INPUT -p tcp --dport 8200 -j DROP

Disable Unused Features

linux

Disable MiniDLNA if not required or limit functionality

sudo systemctl stop minidlna
sudo systemctl disable minidlna

🧯 If You Can't Patch

  • Implement strict network access controls to limit MiniDLNA exposure
  • Deploy web application firewall (WAF) with SQL injection protection rules

🔍 How to Verify

Check if Vulnerable:

Check MiniDLNA version: minidlnad -V or check package version with dpkg -l minidlna

Check Version:

minidlnad -V 2>/dev/null || dpkg -l minidlna 2>/dev/null || rpm -q minidlna 2>/dev/null

Verify Fix Applied:

Verify version is 1.1.0 or higher: minidlnad -V | grep -q '1\.1\.[0-9]' && echo 'Patched'

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in MiniDLNA logs
  • Multiple failed database access attempts
  • Unexpected media database modifications

Network Indicators:

  • SQL injection patterns in HTTP requests to port 8200
  • Unusual outbound connections from MiniDLNA server

SIEM Query:

source="minidlna.log" AND ("sql" OR "database" OR "injection")
