Shodan query for potentially vulnerable WinBox instances (as of 2024):
: While technically a privilege escalation, researchers found that nearly 60% of exposed routers still used the default "admin" user with an empty password, making it trivial for attackers to gain the initial access required. mikrotik routeros authentication bypass vulnerability

This is the most notorious authentication bypass in MikroTik's history, allowing unauthenticated attackers to read arbitrary files, including the user database. 10.0 (Critical) Successful exploitation can lead to full device compromise:
An authentication bypass vulnerability in MikroTik RouterOS allows unauthenticated attackers to gain privileged access to routers by exploiting flaws in the authentication or session-handling logic. Successful exploitation can lead to full device compromise: configuration disclosure, persistent backdoors, arbitrary command execution, and network-wide lateral movement. This article explains the vulnerability class, technical details, detection and exploitation patterns, mitigation and patching guidance, and recommendations for defenders.
The cost of ignoring this vulnerability is no longer a potential data breach—it is an inevitable botnet infection. Patch now or plan your incident response later. In the world of network security, that choice is already made for you.
