Over the weekend, a significant security vulnerability affecting several DrayTek router models was disclosed, putting thousands of businesses at potential risk. As an IT support provider, we want to ensure our clients and readers are fully aware of the issue and know what steps to take.
What’s the Issue?
The vulnerability relates to a flaw in the Web Management Interface of specific DrayTek routers. If left unpatched, this could allow attackers to remotely gain control of the device, bypassing normal authentication. From there, they could potentially:
•Change router settings
•Redirect internet traffic
•Intercept sensitive data
•Use your network for further malicious activity
For businesses relying on these routers for connectivity, this presents a serious risk to data security and network integrity.
Affected Models Include:
•DrayTek Vigor 2862 Series
•DrayTek Vigor 2926 Series
•DrayTek Vigor 2962 & 3910 Series
•Possibly other models with remote management enabled
DrayTek is still investigating and has begun releasing firmware updates to address the issue.
What Should You Do Immediately?
✅ Check Your Router Model and Firmware Version
Visit DrayTek’s official support page and download the latest firmware updates for your device.
✅ Disable Remote Management (If Not Essential)
•Access your router’s management interface.
•Navigate to System Maintenance > Management.
•Disable Remote Management via WAN to prevent external access.
✅ Review Router Logs for Suspicious Activity
If remote access was enabled, check your router logs for any unauthorised login attempts or unusual behaviour.
✅ Change Admin Passwords
Always use strong, unique passwords for your network devices. If you haven’t updated these recently, now is the time.
