Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Missing authentication on a network-reachable endpoint (PR:N, AV:N, AC:L, UI:N) yields unauthenticated root, giving full confidentiality, integrity, and availability impact on the device.

Tenda W20E V16.01.0.6(2782) /goform/telnet endpoint allows unauthenticated remote attackers to activate the Telnet daemon and obtain root shell access.
AnalysisAI
Unauthenticated remote root access affects the Tenda W20E router (firmware V16.01.0.6(2782)) through its /goform/telnet web endpoint, which activates the device's Telnet daemon without any authentication check. Any attacker who can reach the router's management interface can enable Telnet and log in for a root shell, giving full control of the device. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The concrete prerequisite is network reachability of the router's HTTP management interface so the /goform/telnet endpoint can be requested; no credentials, user interaction, or non-default settings are required (CVSS AV:N/AC:L/PR:N/UI:N), consistent with the CWE-306 missing-authentication root cause. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals conflict in a way worth calling out: the CVSS 3.1 base score is 9.8 (network, low complexity, no privileges, no user interaction, full C/I/A impact), which is maximal for a remote root vulnerability, yet the EPSS score is only 0.19% (9th percentile) and it is not in CISA KEV - indicating no evidence of widespread automated exploitation at this time. … 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 identified at time of analysis, so remediation relies on compensating controls. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Tenda W20E devices and disable remote access to the management interface via firewall rules or administrative settings; if remote access is required, restrict it to trusted administrative IPs only. …
