U-speed WIFI4 N300 T1 Pro v1.0.0 is vulnerable to Cleartext transmission of administration credentials over HTTP.
AnalysisAI
Cleartext transmission of administration credentials over HTTP in U-speed WIFI4 N300 T1 Pro v1.0.0 exposes router admin passwords to passive eavesdroppers on the same network segment. Any attacker with adjacent network access - including a co-located wireless client - can capture HTTP session traffic containing unencrypted credentials without any authentication or interaction. …

Vulnerability AssessmentAI
| Exploitation | Adjacent network access is required - the attacker must be on the same LAN segment or within wireless range of the device. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.3 (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) reflects the direct disclosure impact but understates the downstream consequence: capturing router admin credentials on a cleartext channel hands an attacker full administrative control of the device, enabling DNS hijacking, traffic interception, firewall rule modification, and persistent backdoors. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
