Vulnerability
Identifier for a security flaw in the Bandwidth Test service of MikroTik RouterOS, the operating system running on MikroTik network routers.
Federal agencies now have three separate patch deadlines inside twelve days. The lowest-scoring pair of the five flaws added to KEV is the one with a documented 24-day intrusion campaign behind it.
Reality
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.

MikroTik published RouterOS fixes in four branches with no CVE and no technical detail. The same upgrade runs a compromise check and writes a critical log entry marking the device Flagged.

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.
Reality
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.
Reality
CERT Polska reports active exploitation on internet-facing MikroTik routers, where the chain needs no private key and no user interaction, and the fixed builds close the bypass without explaining how attackers learned the account details.
