CWE-306Published: June 20, 2017· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

WiMAX routers based on the MediaTek SDK (libmtk) that use a custom httpd plugin are vulnerable to an authentication bypass allowing a remote, unauthenticated attacker to gain administrator access to the device by performing an administrator password change on the device via a crafted POST request.

Technical Analysis

CVE-2017-3216 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
