CVE-2026-67966: n/a
The Tenda W20E router with firmware version V16.01.0.6(2782) contains a critical vulnerability in the /goform/telnet endpoint. This flaw allows unauthenticated remote attackers to activate the Telnet daemon and gain root shell access on the device.
AI Analysis
Technical Summary
CVE-2026-67966 is a critical remote code execution vulnerability affecting Tenda W20E routers running firmware V16.01.0.6(2782). The vulnerability exists because the /goform/telnet endpoint can be accessed without authentication, enabling attackers to activate the Telnet service and obtain root shell access. This grants full control over the device to an unauthenticated remote attacker.
Potential Impact
Successful exploitation results in complete compromise of the affected device, including unauthorized root-level access. This can lead to full device control, potential network pivoting, and disruption of services. The CVSS score of 9.8 reflects the critical nature of this vulnerability with network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restricting network access to the device and disabling remote management features such as Telnet is recommended to reduce exposure.
