Vulnerability from fkie_nvd - Published: 2021-02-12 00:15 - Updated: 2024-11-21 05:21
Severity ?
8.8 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-1860 firmware version 1.04B03 WiFi extenders. Authentication is not required to exploit this vulnerability. The specific flaw exists within the HNAP service, which listens on TCP port 80 by default. When parsing the Authorization request header, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-10880.

No es requerida una autenticaci\u00f3n para explotar esta vulnerabilidad. El fallo espec\u00edfico se presenta dentro del servicio HNAP, que escucha en el puerto TCP 80 por defecto. Cuando se analiza el encabezado de la petici\u00f3n de autorizaci\u00f3n, el proceso no comprueba apropiadamente una cadena suministrada por el usuario antes de usarla para ejecutar una llamada de sistema.
