Attack-Flow Graph

Executive Summary

The U-speed WIFI4 N300 T1 Pro v1.0.0 router sends administrative credentials in cleartext over HTTP, meaning the login details are transmitted without encryption. This allows attackers on the same network to intercept and steal credentials.

Detection Guidance

To detect this vulnerability, monitor network traffic for HTTP transmissions containing administration credentials. Use packet capture tools like tcpdump or Wireshark to inspect traffic from the U-speed WIFI4 N300 T1 Pro device. Look for POST requests or form submissions over HTTP that may include plaintext credentials.

Impact Analysis

An attacker could capture your admin credentials and gain full control of your router. This could lead to network hijacking, data theft, or unauthorized changes to router settings like DNS or firewall rules.

Mitigation Strategies

Immediately disable HTTP access to the device's administration interface and enforce HTTPS. Update the device firmware if a patch is available. Isolate the device on a separate network segment to limit exposure. Monitor for any unauthorized access attempts.
