CVE-2024-44381
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary commands on D-Link DI-8004W routers through the jhttpd msp_info_htm function. Attackers can gain full control of affected devices without authentication. All users of D-Link DI-8004W routers with vulnerable firmware are affected.
💻 Affected Systems
- D-Link DI-8004W
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of router allowing attackers to intercept all network traffic, install persistent malware, pivot to internal networks, and use device as botnet node.
Likely Case
Router takeover leading to DNS hijacking, credential theft from network traffic, and installation of cryptocurrency miners or ransomware.
If Mitigated
Limited impact if device is behind firewall with strict inbound rules and network segmentation prevents lateral movement.
🎯 Exploit Status
Public proof-of-concept available on GitHub. Exploitation requires sending crafted HTTP requests to vulnerable endpoint.

🔧 Temporary Workarounds
Block External Access
linuxConfigure firewall to block all inbound WAN access to router management interface
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
Disable Remote Management
allTurn off remote management feature in router settings
🧯 If You Can't Patch
- Isolate router on separate VLAN with strict network segmentation
- Implement network monitoring for unusual HTTP requests to router management interface
🔍 How to Verify
Check if Vulnerable:
Check firmware version in router admin interface under System Status or Firmware Update sectionCheck Version:
curl -s http://router-ip/status.html | grep -i firmwareVerify Fix Applied:
Verify firmware version has been updated to version newer than 16.07.26A1📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP POST requests to msp_info_htm endpoint
- Multiple failed login attempts followed by command execution patterns
Network Indicators:
- HTTP requests containing shell commands or encoded payloads to router IP
- Outbound connections from router to suspicious IPs
