📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete router compromise allowing attacker to change administrative credentials, intercept network traffic, deploy malware to connected devices, and use the router as an attack platform.

🟠

Likely Case

Unauthorized administrative access to router configuration, enabling network traffic monitoring, DNS hijacking, and potential lateral movement to connected devices.

🟢

If Mitigated

Limited impact if strong network segmentation exists and router management interface is not internet-facing.

🌐 Internet-Facing: HIGH - The vulnerability is remotely exploitable and public exploit details exist, making internet-facing devices prime targets.
🏢 Internal Only: MEDIUM - Internal attackers or compromised internal systems could exploit this to gain router administrative access.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploit details are publicly available on GitHub. The vulnerability requires access to the management interface but doesn't require authentication for exploitation.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: UNKNOWN

Vendor Advisory: NONE

Restart Required: No

Change Default Credentials

all

Use strong, unique administrative passwords

Access router admin panel -> System -> Change Password -> Set strong password

🧯 If You Can't Patch

  • Isolate router management interface to trusted internal network only
  • Implement network segmentation to limit potential lateral movement

🔍 How to Verify

Check if Vulnerable:

Check router firmware version in admin panel. If version is 221110, device is vulnerable.

Check Version:

Login to router admin interface and check System Information or Firmware Version

Verify Fix Applied:

Verify firmware version has been updated to a version later than 221110

📡 Detection & Monitoring

Log Indicators:

  • Multiple failed login attempts followed by successful login
  • Unusual password reset or recovery requests
  • Access to /sysinit.html from unexpected IP addresses

Network Indicators:

  • HTTP POST requests to /sysinit.html with newpass/confpass parameters
  • Unusual administrative access patterns to router management interface

SIEM Query:

source="router_logs" AND (uri="/sysinit.html" OR (event="password_change" AND success=true AND user="admin"))
