CVE-2025-15136
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary commands on TRENDnet TEW-800MB routers by injecting malicious commands through the management interface. Attackers can exploit this to gain full control of affected devices. Only TRENDnet TEW-800MB routers running firmware version 1.0.1.0 are affected.
💻 Affected Systems
- TRENDnet TEW-800MB
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing attackers to install persistent backdoors, pivot to internal networks, intercept traffic, or use the device as part of a botnet.
Likely Case
Attackers gain shell access to execute commands, potentially modifying device configuration, stealing credentials, or launching attacks against internal networks.
If Mitigated
If properly segmented and monitored, impact limited to the device itself with no lateral movement to other systems.
🎯 Exploit Status
Exploit details are publicly available. Attack requires access to the management interface but no authentication is needed for the vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown

allIsolate the router from critical networks and restrict access to management interface
🧯 If You Can't Patch
- Replace affected devices with supported models
- Implement strict network access controls to limit exposure
🔍 How to Verify
Check if Vulnerable:
Check firmware version in router web interface. If version is 1.0.1.0, device is vulnerable.Check Version:
Check router web interface at http://[router-ip]/ or use telnet/ssh if enabledVerify Fix Applied:
No fix available to verify. Consider device replacement.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /goform/wizardset with command injection patterns
- Unexpected system command execution in router logs
Network Indicators:
- Unusual outbound connections from router
- Traffic patterns suggesting command and control activity
SIEM Query:
