W systemie operacyjnym RouterOS, stosowanym w routerach MikroTik, zidentyfikowano 6 podatno\u015bci. Kombinacja dw\u00f3ch z nich umo\u017cliwia zdalne uzyskanie pe\u0142nej kontroli nad urz\u0105dzeniem z uprawnieniami administratora, o ile jest ono dost\u0119pne przez SSH. Zarejestrowano przypadki wykorzystania tych podatno\u015bci. \u0141atki od Mikrotika s\u0105 dost\u0119pne od 3 wrze\u015bnia (RouterOS 7.25 beta 3, 7.24.2, 7.23.4, 6.49.21) i prawdopodobnie napastnicy byli w stanie okre\u015bli\u0107 istot\u0119 podatno\u015bci na podstawie tych \u0142atek. <\/p>\n

Podatno\u015bci CVE-2026-67276 i CVE-2026-86060 otrzyma\u0142y krytyczny poziom zagro\u017cenia (9.2 w skali 10). Pierwszy problem jest spowodowany nieprawid\u0142ow\u0105 weryfikacj\u0105 otwartych kluczy RSA u\u017cywanych podczas uwierzytelniania przez SSH. Znaj\u0105c nazw\u0119 u\u017cytkownika i parametry otwartego klucza, atakuj\u0105cy m\u00f3g\u0142 utworzy\u0107 fa\u0142szywy klucz i po\u0142\u0105czy\u0107 si\u0119 przez SSH bez dost\u0119pu do klucza prywatnego. Drugi problem dotyczy braku filtrowania niedozwolonych znak\u00f3w na pocz\u0105tku nazwy u\u017cytkownika podczas przetwarzania logowania przez SSH. <\/p>\n

Udane wykorzystanie podatno\u015bci mo\u017cna \u015bledzi\u0107 w zapisach log\u00f3w RouterOS: login failure for user -2 from via ssh user added by ssh:-2@
