Kombinationen af to af disse tillader fjernadgang med fuld kontrol over enheden med administratorrettigheder, forudsat at den er tilg\u00e6ngelig via SSH. Der er registreret tilf\u00e6lde af udnyttelse af de n\u00e6vnte s\u00e5rbarheder. Patches fra MikroTik er tilg\u00e6ngelige fra den 3. september (RouterOS 7.25 beta 3, 7.24.2, 7.23.4, 6.49.21), og det er sandsynligt, at angribere kunne identificere s\u00e5rbarhedernes art baseret p\u00e5 disse patches.       <\/p>\n<p>S\u00e5rbarhederne CVE-2026-67276 og CVE-2026-86060 er klassificeret som kritisk (9.2 af 10). Det f\u00f8rste problem skyldes en forkert kontrol af de \u00e5bne RSA-n\u00f8gler, der bruges til autentificering via SSH. Ved at kende brugernavnet og parametrene for brugerens \u00e5bne n\u00f8gle kunne en angriber fremstille en falsk n\u00f8gle og oprette forbindelse via SSH uden adgang til den lukkede n\u00f8gle. Det andet problem er relateret til manglende filtrering af ugyldige tegn i begyndelsen af brugernavnet ved behandling af login via SSH.    <\/p>\n<p>Succesfuld udnyttelse af s\u00e5rbarhederne kan spores gennem logoptegnelser i RouterOS: login failure for user -2 from  via ssh user  added by ssh:-2@<br \/>\n<br \/>Kilde: <a content=\"nofollow\" rel=\"nofollow\"
