CVE-2017-10832

9.8 CRITICAL

📋 TL;DR

This vulnerability allows remote attackers to execute arbitrary operating system commands on affected 'Dokodemo eye Smart HD' SCR02HD devices. Attackers can potentially take full control of the device without authentication. All users of SCR02HD firmware version 1.0.3.1000 and earlier are affected.

💻 Affected Systems

Products:
  • Dokodemo eye Smart HD SCR02HD
Versions: Firmware 1.0.3.1000 and earlier
Operating Systems: Embedded Linux (device-specific)
Default Config Vulnerable: ⚠️ Yes
Notes: All default configurations are vulnerable. No special configuration required for exploitation.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete device compromise allowing attackers to install persistent malware, pivot to internal networks, or use device as botnet node.

🟠

Likely Case

Remote code execution leading to device takeover, data exfiltration, or denial of service.

🟢

If Mitigated

Limited impact if device is isolated from internet and internal networks with strict network segmentation.

🌐 Internet-Facing: HIGH - Directly accessible from internet with unauthenticated command execution.
🏢 Internal Only: HIGH - Even internally, this provides full device compromise capability.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Unspecified vectors but CVSS 9.8 suggests trivial exploitation. No authentication required.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Firmware newer than 1.0.3.1000

Vendor Advisory: http://www.nippon-antenna.co.jp/product/ine/pdf/scr02hd_about_security.pdf

Restart Required: Yes

Instructions:

1. Download latest firmware from vendor website. 2. Follow device-specific firmware update procedure. 3. Reboot device after update completes.

🔧 Temporary Workarounds

Network Isolation

linux

Block all external access to device and restrict internal network access

iptables -A INPUT -p tcp --dport [device_port] -j DROP
iptables -A INPUT -p udp --dport [device_port] -j DROP

Access Control Lists

all

Implement strict network ACLs to limit device communication

🧯 If You Can't Patch

  • Immediately disconnect device from internet and critical networks
  • Implement strict network segmentation with firewall rules blocking all unnecessary traffic

🔍 How to Verify

Check if Vulnerable:

Check firmware version via device web interface or SSH if enabled. Version 1.0.3.1000 or earlier indicates vulnerability.

Check Version:

Check device web interface or use vendor-specific CLI commands if available

Verify Fix Applied:

Verify firmware version is newer than 1.0.3.1000 after update.

📡 Detection & Monitoring

Log Indicators:

  • Unusual command execution in system logs
  • Unexpected process creation
  • Network connections from device to suspicious IPs

Network Indicators:

  • Unusual outbound connections from device
  • Command injection patterns in HTTP requests
  • Unexpected port scanning from device

SIEM Query:

source="device_logs" AND (command="*sh*" OR command="*bash*" OR command="*cmd*") AND user="unauthenticated"
