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.

Security readout for executives and security teams

Certain WiMAX customer routers can let someone who can reach the device change the administrator password without logging in. That could hand over control of the router, affecting connectivity, configuration, and downstream traffic handling. Exposure is most likely where affected WiMAX router management interfaces are reachable from untrusted networks. Internet-facing or provider-managed CPE fleets are higher concern. The source bundle does not prove broad deployment, current support status, or exact affected firmware for every listed model. Prioritize exposed or provider-managed WiMAX router fleets. The business risk is device takeover, service disruption, and loss of administrative control. Urgency is lower for unreachable retired devices, but unknown patch status raises replacement pressure. Mitigation focus: Check vendor or ISP guidance for affected models and firmware.; Remove management interfaces from internet or untrusted network exposure.; Restrict administrative access to trusted management networks only..
