Two chained RouterOS SSH flaws give attackers admin on exposed MikroTik routers, CERT Polska says

CERT Polska disclosed MikroTrick, a chain of two RouterOS flaws that gives unauthenticated admin on routers whose SSH faces the internet. Attacks were already under way at disclosure. Reachable SSH is the one condition the chain needs.

Argument injection in RouterOS's SSH login hands an attacker full-group admin

CVE-2026-86060, the privilege half of the MikroTrick chain CERT Polska analysed, lets an SSH client set its own policy mask and take RouterOS full-group admin. The September 2026 releases fix it, and a scan found 9,559 devices reachable over SSH.

Exposed MikroTik SSH hands over full administrative control without authentication

CERT Polska dated successful attacks to at least September 2 and published its warning on September 5, so operators who deferred the RouterOS update have three days of configuration changes to read as well as a patch to install.

CERT Polska rebuilt MikroTik's silent RouterOS patch into a working exploit within days

CERT Polska rebuilt the MikroTrick attack chain from MikroTik's unlabeled September 3 patch and had a working exploit for CVE-2026-86060 in about an hour. The fix quietly disables a rogue "ops" account, evidence the chain was already exploited in the wild.

Firewalling RouterOS SSH to a management network removes MikroTrick's precondition

CERT Polska confirmed exploitation of the MikroTrick chain on September 5, and the two bugs need no password and no private key, only a reachable SSH service, so the firewall rule scopes the risk before any build audit can.

A prohibited leading character in a RouterOS username rewrites the session's policy mask

Two RouterOS flaws published to NVD on 2026-09-05 both sit in code that runs before a session has proven who it is. An upgrade closes them. Which management services answer from the internet is still an open question.
