CVE-2020-10208
📋 TL;DR
This CVE describes a command injection vulnerability in EntoneWebEngine used by Amino Communications set-top boxes. Authenticated remote attackers can execute arbitrary commands with root privileges, potentially taking full control of affected devices. This affects multiple Amino Communications set-top box series used by internet service providers.
💻 Affected Systems
- Amino Communications AK45x series
- AK5xx series
- AK65x series
- Aria6xx series
- Aria7/AK7Xx series
- Kami7B
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of set-top boxes allowing attackers to install persistent malware, pivot to internal networks, intercept communications, or create botnets for DDoS attacks.
Likely Case
Attackers gain root access to set-top boxes, potentially modifying configurations, stealing user data, or using devices as entry points to service provider networks.
If Mitigated
With proper network segmentation and authentication controls, impact limited to isolated set-top box devices without network access to critical systems.
🎯 Exploit Status
Exploit details published in Medium article showing command injection via web interface parameters.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No public vendor advisory found
Restart Required: Yes
Instructions:
Contact Amino Communications for firmware updates. Check with your ISP for patched firmware versions.
🔧 Temporary Workarounds
Network Segmentation
allIsolate set-top boxes from critical network segments and restrict outbound internet access
Authentication Hardening
allChange default credentials and implement strong authentication policies
🧯 If You Can't Patch
- Implement strict network access controls to limit set-top box communication to only required services
- Monitor for unusual outbound connections or command execution patterns from set-top boxes
🔍 How to Verify
Check if Vulnerable:
Check if device runs affected Amino firmware and has EntoneWebEngine accessible. Test for command injection via web interface parameters.Check Version:
Check firmware version via device web interface or consult ISP documentationVerify Fix Applied:
Verify firmware version against patched releases from vendor. Test that command injection attempts no longer succeed.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in system logs
- Multiple failed authentication attempts followed by successful login
- Web interface requests with shell metacharacters in parameters
Network Indicators:
- Unexpected outbound connections from set-top boxes
- Traffic to known malicious IPs from set-top box network segment
