I operativsystemet RouterOS, der anvendes i MikroTik-routere, er der identificeret en kritisk s\u00e5rbarhed (CVE-2023-32154), der tillader en uautoriseret bruger at eksekvere kode eksternt p\u00e5 enheden ved at sende en specielt formateret IPv6-routerannoncering (RA, Router Advertisement). <\/p>\n

Problemet skyldes manglen p\u00e5 tilstr\u00e6kkelig validering af indg\u00e5ende data i processen, der h\u00e5ndterer IPv6 RA (Router Advertisement) anmodninger. Dette gjorde det muligt at skrive data uden for den tildelte buffer og udf\u00f8re egen kode med root-rettigheder. S\u00e5rbarheden forekommer i versioner af MikroTik RouterOS v6.xx og v7.xx, n\u00e5r indstillingerne for modtagelse af IPv6 RA-beskeder er aktiveret («ipv6\/settings\/set accept-router-advertisements=yes» eller «ipv6\/settings\/set forward=no accept-router-advertisements=yes-if-forwarding-disabled»). <\/p>\n

Muligheden for praktisk udnyttelse af s\u00e5rbarheden blev demonstreret ved Pwn2Own-konkurrencen i Toronto, hvor forskere, der identificerede problemet, modtog en bel\u00f8nning p\u00e5 $100,000 for en flertrins-hacking af infrastrukturen med angreb p\u00e5 en MikroTik-router og brugen af denne som springbr\u00e6t til angreb p\u00e5 andre komponenter i det lokale netv\u00e6rk (efterf\u00f8lgende fik angriberne kontrol over en Canon-printer, oplysninger om s\u00e5rbarheden i denne blev ogs\u00e5 offentliggjort). <\/p>\n

Information om s\u00e5rbarheden blev oprindeligt offentliggjort f\u00f8r producenten havde udviklet en rettelse (0-day), men der er nu offentliggjort opdateringer til RouterOS 7.9.1, 6.49.8, 6.48.7, 7.10beta8, som adresserer s\u00e5rbarheden. If\u00f8lge oplysninger fra ZDI-projektet (Zero Day Initiative), som afholder Pwn2Own-konkurrencen, blev producenten informeret om s\u00e5rbarheden den 29. december 2022. Repr\u00e6sentanter for MikroTik h\u00e6vder, at de ikke havde modtaget nogen meddelelse og f\u00f8rst h\u00f8rte om problemet den 10. maj efter at have modtaget en endelig meddelelse om offentligg\u00f8relse. Desuden omtaler rapporten om s\u00e5rbarheden, at informationen om problemet blev videregivet til en repr\u00e6sentant for MikroTik personligt under Pwn2Own i Toronto, men if\u00f8lge MikroTik deltog virksomhedens medarbejdere ikke i arrangementet i nogen kapacitet.
