FKIE_CVE-2025-34147

Vulnerability from fkie_nvd - Published: 2025-08-04 18:15 - Updated: 2026-06-17 09:13
Severity
9.4 (Critical) - CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
Summary
An unauthenticated OS command injection vulnerability exists in the Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02). When configuring the device in Extender mode via its captive portal, the extap2g SSID field is inserted unescaped into a reboot-time shell script. This allows remote attackers within Wi-Fi range to inject arbitrary shell commands that execute as root during device reboot, leading to full system compromise.

Al configurar el dispositivo en modo extensor a trav\u00e9s de su portal cautivo, el campo SSID de extap2g se inserta sin escape en un script de shell durante el reinicio. Esto permite a atacantes remotos dentro del alcance Wi-Fi inyectar comandos de shell arbitrarios que se ejecutan como root durante el reinicio del dispositivo, lo que compromete por completo el sistema."
