MikroTik router flaws allow takeover without a password
Attackers actively exploit chained MikroTik RouterOS SSH flaws CVE-2026-67276 and CVE-2026-86060, bypassing authentication and escalating to admin to seize edge routers.
CERT Polska warns of active exploitation of a two-flaw chain dubbed 'MikroTrick' against internet-exposed MikroTik RouterOS devices with SSH remote management enabled. CVE-2026-67276 is an SSH authentication bypass in RSA public-key handling, and CVE-2026-86060 is a privilege-escalation flaw triggered via a specially crafted username, letting attackers gain full administrator control without a password. Patched RouterOS packages are already public, and MikroTik added a startup detection that flags unauthorized configuration changes. Compromised edge routers enable DNS hijacking, traffic capture, remote-access tunnels, firewall changes, and lateral attacks.
