Multiple high-severity authentication bypass vulnerabilities have been discovered in MikroTik RouterOS over the past several years. The most notorious of these (CVE-2018-14847) allows an unauthenticated attacker to read arbitrary files from the router’s filesystem and, in many cases, escalate to full administrative control. Despite patches being available since 2018, thousands of devices remain vulnerable due to poor update hygiene.
An unauthenticated attacker can bypass login credentials and gain to a MikroTik router by sending a specially crafted packet to the WinBox or HTTP management ports (default: 8291, 80, 443). mikrotik routeros authentication bypass vulnerability
Attackers create VPN tunnels (L2TP, SSTP, or OVPN) directly through the compromised router. They become an endpoint on your internal LAN, bypassing your perimeter firewalls. An unauthenticated attacker can bypass login credentials and
Once authenticated (bypass), an attacker can read arbitrary files using a WinBox file request: Once authenticated (bypass), an attacker can read arbitrary
