CVE-2025-60572
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on D-Link DIR600L routers by exploiting a buffer overflow in the formAdvNetwork function. Attackers can gain full control of affected devices by sending specially crafted requests. Only users of specific D-Link router models with vulnerable firmware are affected.
💻 Affected Systems
- D-Link DIR600L
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device takeover leading to persistent backdoor installation, network traffic interception, credential theft, and lateral movement to other network devices.
Likely Case
Router compromise allowing attackers to modify network settings, redirect DNS, intercept traffic, and use the device as a foothold for further attacks.
If Mitigated
Limited impact if devices are behind firewalls with strict inbound filtering and network segmentation prevents lateral movement.
🎯 Exploit Status
Public proof-of-concept code exists in GitHub repository. Exploitation requires sending crafted HTTP requests to the router's web interface.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: Yes
Instructions:
1. Check D-Link website for firmware updates for DIR600L. 2. Download latest firmware. 3. Log into router admin interface. 4. Navigate to firmware update section. 5. Upload and apply new firmware. 6. Wait for router to reboot.
🔧 Temporary Workarounds
Disable Remote Management
allPrevent external access to router web interface
Network Segmentation
allIsolate router management interface from untrusted networks
🧯 If You Can't Patch
- Replace vulnerable router with supported model
- Implement strict firewall rules blocking all inbound traffic to router management interface
🔍 How to Verify
Check if Vulnerable:
Check router firmware version in admin interface. If version is FW116WWb01, device is vulnerable.Check Version:
Log into router web interface and check System Status or Firmware Update sectionVerify Fix Applied:
Verify firmware version has changed from FW116WWb01 to a newer version after update.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP POST requests to formAdvNetwork endpoint
- Multiple failed login attempts followed by buffer overflow patterns
- Router reboot events after suspicious requests
Network Indicators:
- HTTP requests with unusually long curTime parameter values
- Traffic patterns suggesting router compromise (unexpected outbound connections)
