CVE-2024-46484

9.8 CRITICAL

📋 TL;DR

This vulnerability allows remote attackers to execute arbitrary operating system commands on TRENDnet TV-IP410 vA1.0R security cameras via the /server/cgi-bin/testserv.cgi component. Attackers can gain complete control of affected devices without authentication. Organizations using these specific camera models are affected.

💻 Affected Systems

Products:
  • TRENDnet TV-IP410
Versions: vA1.0R
Operating Systems: Embedded Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Affects the specific hardware revision A1.0R. The testserv.cgi component appears to be part of the default web interface.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete device compromise allowing attackers to pivot to internal networks, install persistent malware, disable security functions, or use the device for botnet participation.

🟠

Likely Case

Remote code execution leading to camera compromise, credential theft, network reconnaissance, and potential lateral movement within the network.

🟢

If Mitigated

Limited impact if devices are isolated in separate VLANs with strict network segmentation and egress filtering.

🌐 Internet-Facing: HIGH - The vulnerability is remotely exploitable without authentication and affects internet-facing security cameras.
🏢 Internal Only: HIGH - Even internally, the vulnerability allows complete device takeover and potential network pivoting.

🎯 Exploit Status

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

The GitHub gist contains technical details that could be easily weaponized. No authentication is required to exploit.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: http://trendnet.com

Restart Required: No

Instructions:

1. Check TRENDnet's security advisory page for firmware updates. 2. If available, download the latest firmware. 3. Upload via the camera's web interface. 4. Verify the update completed successfully.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate cameras in a separate VLAN with strict firewall rules blocking all unnecessary traffic.

Access Control

all

Block external access to the camera web interface and restrict internal access to management networks only.

🧯 If You Can't Patch

  • Immediately disconnect affected cameras from the internet and place them behind strict firewall rules.
  • Consider replacing affected cameras with newer models that receive security updates.

🔍 How to Verify

Check if Vulnerable:

Check if the camera responds to requests at /server/cgi-bin/testserv.cgi and if the firmware version is vA1.0R.

Check Version:

Check via camera web interface: Settings > System > Firmware Version

Verify Fix Applied:

Verify the testserv.cgi endpoint no longer accepts malicious input or has been removed. Check firmware version against vendor's patched version.

📡 Detection & Monitoring

Log Indicators:

  • Unusual POST requests to /server/cgi-bin/testserv.cgi
  • Suspicious command execution patterns in system logs
  • Unexpected network connections from camera

Network Indicators:

  • HTTP requests containing shell metacharacters or command injection patterns
  • Unusual outbound traffic from camera to external IPs

SIEM Query:

source="camera_logs" AND (uri="/server/cgi-bin/testserv.cgi" OR command="*;*" OR command="*|*" OR command="*`*" OR command="*$(*")
