CVE-2024-10119
📋 TL;DR
CVE-2024-10119 is a critical OS command injection vulnerability in SECOM WRTM326 wireless routers that allows unauthenticated remote attackers to execute arbitrary system commands. This affects all organizations using these routers, potentially giving attackers full control over the device. The vulnerability stems from improper input validation of a specific parameter in router requests.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of router with persistent backdoor installation, credential theft, network pivoting to internal systems, and router bricking.
Likely Case
Router takeover for botnet recruitment, DNS hijacking, credential harvesting, and network traffic interception.
If Mitigated
Limited impact if routers are behind firewalls with strict inbound filtering and network segmentation.
🎯 Exploit Status
No public PoC yet, but CVSS 9.8 with unauthenticated remote execution suggests weaponization is likely. Attack requires crafted HTTP requests to vulnerable parameter.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check with SECOM for specific firmware version
Vendor Advisory: https://www.twcert.org.tw/en/cp-139-8157-e0461-2.html
Restart Required: Yes
Instructions:
1. Check SECOM website for firmware updates. 2. Download latest firmware. 3. Log into router admin interface. 4. Navigate to firmware update section. 5. Upload and apply new firmware. 6. Reboot router.
🔧 Temporary Workarounds
Disable WAN Management
allPrevent external access to router management interface
Login to router admin → Security/Remote Management → Disable WAN/Remote Access
Network Segmentation
allIsolate router management interface from untrusted networks
Configure firewall rules to block external access to router management ports (typically 80, 443, 8080)
🧯 If You Can't Patch
- Place router behind firewall with strict inbound rules blocking all external access to management interfaces
- Implement network monitoring for unusual outbound connections from router and unexpected configuration changes
🔍 How to Verify
Check if Vulnerable:
Check router firmware version against SECOM's patched version list. Monitor for unexpected processes or configuration changes.Check Version:
Login to router admin interface → System Status/About → Check Firmware VersionVerify Fix Applied:
Verify firmware version matches patched version from SECOM advisory. Test that crafted requests no longer execute commands.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP requests with command injection patterns
- Unexpected system process execution in router logs
- Configuration changes from unknown sources
Network Indicators:
- Unusual outbound connections from router
- Traffic to known malicious IPs from router
- DNS queries to suspicious domains from router
SIEM Query:
source="router_logs" AND (http_request="*cmd=*" OR http_request="*;*" OR http_request="*|*" OR http_request="*`*" OR process="unexpected_process")
