La vulnerabilidad se presenta en las ramas MikroTik RouterOS v6.xx y v7.xx, al habilitar en la configuraci\u00f3n la recepci\u00f3n de mensajes IPv6 RA (\"ipv6\/settings\/set accept-router-advertisements=yes\" o \"ipv6\/settings\/set forward=no accept-router-advertisements=yes-if-forwarding-disabled\").          <\/p>\n<p>La posibilidad de explotar la vulnerabilidad en la pr\u00e1ctica fue demostrada en la competici\u00f3n Pwn2Own en Toronto, donde los investigadores que descubrieron el problema recibieron una recompensa de $100,000 por la pirater\u00eda en m\u00faltiples etapas de la infraestructura, atacando el enrutador MikroTik y utiliz\u00e1ndolo como punto de apoyo para atacar otros componentes de la red local (posteriormente, los atacantes obtuvieron el control de una impresora Canon, cuya vulnerabilidad tambi\u00e9n fue divulgada).       <\/p>\n<p>La informaci\u00f3n sobre la vulnerabilidad fue publicada inicialmente antes de que se desarrollara un parche por parte del fabricante (0-day), pero actualmente ya se han lanzado actualizaciones RouterOS 7.9.1, 6.49.8, 6.48.7, 7.10beta8 que corrigen la vulnerabilidad. Seg\u00fan informaci\u00f3n del proyecto ZDI (Zero Day Initiative), que lleva a cabo la competici\u00f3n Pwn2Own, el fabricante fue notificado de la vulnerabilidad el 29 de diciembre de 2022. Los representantes de MikroTik afirman que no recibieron notificaci\u00f3n y se enteraron del problema solo el 10 de mayo, tras el env\u00edo de una advertencia final sobre la divulgaci\u00f3n de informaci\u00f3n. Adem\u00e1s, en el informe de vulnerabilidad se menciona que la informaci\u00f3n sobre la naturaleza del problema se transmiti\u00f3 a un representante de MikroTik en privado durante la competici\u00f3n Pwn2Own en Toronto, pero seg\u00fan MikroTik, los empleados de la empresa no participaron en el evento en ning\u00fan papel.<br \/>\n<br \/>Fuente: <a content=\"nofollow\"
