Kombinasjonen av to av dem gj\u00f8r det mulig \u00e5 f\u00e5 full kontroll over enheten eksternt med administratorrettigheter, forutsatt at enheten er tilgjengelig via SSH. Det er registrert tilfeller av utnyttelse av de identifiserte s\u00e5rbarhetene. Lapper fra MikroTik har v\u00e6rt tilgjengelige siden 3. september (RouterOS 7.25 beta 3, 7.24.2, 7.23.4, 6.49.21), og det er sannsynlig at angriperne har klart \u00e5 forst\u00e5 essensen av s\u00e5rbarhetene basert p\u00e5 disse lappene.       <\/p>\n<p>S\u00e5rbarhetene CVE-2026-67276 og CVE-2026-86060 er vurdert til kritisk fare (9.2 av 10). Det f\u00f8rste problemet skyldes feilaktig validering av \u00e5pne RSA-n\u00f8kler brukt ved autentisering via SSH. Ved \u00e5 kjenne brukernavnet og parameterne for brukerens \u00e5pne n\u00f8kkel, kunne angriperen lage en falsk n\u00f8kkel og koble til via SSH uten tilgang til den lukkede n\u00f8kkelen. Det andre problemet er mangelen p\u00e5 filtrering av ugyldige tegn i begynnelsen av brukernavnet under behandling av innlogging via SSH.    <\/p>\n<p>Supert utnyttelse av s\u00e5rbarhetene kan spores
