CVE-2024-4582

7.3 HIGH

📋 TL;DR

This critical vulnerability allows remote attackers to execute arbitrary operating system commands on Faraday GM8181 and GM828x DVR devices by injecting malicious commands into the NTP service configuration. Affected systems are vulnerable to complete compromise if exposed to untrusted networks. The vulnerability affects all versions up to April 29, 2024.

💻 Affected Systems

Products:
  • Faraday GM8181
  • Faraday GM828x
Versions: All versions up to 20240429
Operating Systems: Embedded Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Affects the NTP service component specifically when configuring NTP servers. All devices with default configurations are vulnerable.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system takeover with root/administrator privileges, installation of persistent backdoors, data exfiltration, and use as pivot point for lateral movement within the network.

🟠

Likely Case

Remote code execution leading to device compromise, credential theft, surveillance system manipulation, and potential ransomware deployment.

🟢

If Mitigated

Limited impact if devices are isolated in segmented networks with strict egress filtering and no internet exposure.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Public exploit script available. Attack requires network access to the NTP service port (typically UDP 123).

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Versions after 20240429

Vendor Advisory: Not provided in references

Restart Required: Yes

Instructions:

1. Contact Faraday Technology for updated firmware. 2. Backup device configuration. 3. Upload and install firmware update via web interface or console. 4. Reboot device. 5. Verify NTP service is functioning correctly.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate DVR devices in separate VLAN with strict firewall rules blocking inbound access to NTP service from untrusted networks.

Disable NTP Service

linux

Temporarily disable NTP synchronization if not required for operation.

systemctl stop ntp
systemctl disable ntp

🧯 If You Can't Patch

  • Implement strict network access controls allowing only trusted NTP servers
  • Deploy network-based intrusion prevention systems with command injection detection rules

🔍 How to Verify

Check if Vulnerable:

Check device firmware version via web interface or SSH. If version is 20240429 or earlier, device is vulnerable.

Check Version:

cat /etc/version or check web interface system information page

Verify Fix Applied:

Verify firmware version is newer than 20240429 and attempt to reproduce exploit using safe test payloads.

📡 Detection & Monitoring

Log Indicators:

  • Unusual command execution in system logs
  • Failed NTP service restarts
  • Suspicious process creation from NTP service

Network Indicators:

  • Malformed NTP packets containing shell metacharacters
  • Unexpected outbound connections from DVR devices

SIEM Query:

source="dvr_logs" AND (process="ntp" AND command="*;*" OR command="*|*" OR command="*`*" OR command="*$(*")
