MikroTrick chains two MikroTik RouterOS flaws for unauthenticated admin access, with exploitation seen before patches.

CERT Polska reconstructed MikroTrick, a chain of MikroTik RouterOS flaws CVE-2026-67279 and CVE-2026-86060 that yields full administrative access without authentication. An SSH rekey during login skips authentication, and an unsanitized username argument lets the attacker supply a fully privileged policy; logs show a failed login for user "-2" and creation of an "ops" admin account. MikroTik patched on September 3, 2026. CERT Polska says the chain was used before the patches, with source IP 82.192.72.4 pulling diagnostic files from compromised routers. Researchers used GPT-5.5-cyber and GPT-5.6-sol to help recover the bugs within days of the silent update.

Key facts
  • MikroTrick chains CVE-2026-67279 and CVE-2026-86060 into unauthenticated admin access.
  • Logs show a failed "-2" login followed by a privileged "ops" account.
  • CERT Polska ties attempts to 82.192.72.4, including stolen diagnostic files.
  • MikroTik patched on September 3, 2026; public analysis followed within days.
  • GPT-5.5-cyber and GPT-5.6-sol assisted binary and protocol analysis.
