CVE-2026-2928
📋 TL;DR
A stack-based buffer overflow vulnerability in D-Link DWR-M960 routers allows remote attackers to execute arbitrary code by manipulating the submit-url parameter in the WLAN encryption configuration endpoint. This affects D-Link DWR-M960 routers running firmware version 1.01.07. Attackers can exploit this without authentication to potentially take full control of affected devices.
💻 Affected Systems
- D-Link DWR-M960
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, lateral movement to internal networks, persistent backdoor installation, and data exfiltration.
Likely Case
Remote code execution allowing attackers to modify router settings, intercept network traffic, or use the device as part of a botnet.
If Mitigated
Limited impact if devices are behind firewalls with strict ingress filtering and network segmentation.
🎯 Exploit Status
Exploit details are publicly available on GitHub. The vulnerability requires sending specially crafted HTTP requests to the vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.dlink.com/
Restart Required: Yes
Instructions:
1. Check D-Link website for firmware updates 2. Download latest firmware 3. Access router admin interface 4. Navigate to firmware update section 5. Upload and apply new firmware 6. Reboot router
🔧 Temporary Workarounds
Disable Remote Management
allPrevent external access to router management interface
Access router admin panel -> Advanced -> Remote Management -> Disable
Network Segmentation
allIsolate router management interface from untrusted networks
Configure firewall rules to restrict access to router IP on ports 80/443
🧯 If You Can't Patch
- Implement strict network access controls to limit access to router management interface
- Monitor network traffic for exploitation attempts and unusual router behavior
🔍 How to Verify
Check if Vulnerable:
Check router firmware version via admin interface. If version is 1.01.07, device is vulnerable.Check Version:
Login to router admin interface and check System Status or Firmware Update sectionVerify Fix Applied:
Verify firmware version has been updated to a version later than 1.01.07📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP POST requests to /boafrm/formWlEncrypt
- Multiple failed authentication attempts to router interface
- Router configuration changes without authorized user activity
Network Indicators:
- Unusual outbound connections from router
- Traffic patterns suggesting command and control communication
- Port scanning originating from router
SIEM Query:
source="router_logs" AND (uri="/boafrm/formWlEncrypt" OR method="POST" AND uri CONTAINS "formWlEncrypt")
