MikroTik RouterOS SSH flaws chained in active router hijacking attacks

Attackers are combining two newly disclosed MikroTik RouterOS vulnerabilities, an SSH authentication bypass (CVE-2026-67276) and a privilege escalation bug (CVE-2026-86060), to seize full control of routers with SSH exposed to the internet. Poland's CERT, which found the flaws with AI assistance, calls the combined exploit 'MikroTrick' and confirms it is being used in real-world attacks. MikroTik patched the issues in RouterOS versions released September 3, alongside a related bandwidth-test flaw that can leak memory or crash devices.

Researchers reverse-engineer MikroTik's undisclosed RouterOS 7.23.4 security patch

MikroTik simultaneously released RouterOS 7.23.4, 7.24.2 and 6.49.21 on September 3, 2026, each flagging an unspecified 'important security update' without disclosing details. A security researcher reverse-engineered the binary diffs across versions and identified two exploitable flaws: a low-exponent RSA signature forgery leading to an mtget buffer overflow, and an SSH authentication bug where a username value of -2 grants a read-only session elevated privileges, enabling full command execution on the router.
