Technical details
The vulnerability is an authentication bypass in ASUS router firmware where a critical function exposed over HTTP lacks access controls. An attacker within network proximity can send specially crafted HTTP requests to trigger device identification disclosure and mode switching. The impact is limited to information exposure and self-recovery disabling when abnormal conditions occur; no code execution or unauthorized configuration changes are indicated.
