(WinBox User Enumeration): A more recent flaw in the WinBox service allowed attackers to confirm user account existence via brute-forcing the login process, affecting versions v6.43 through v7.17.2. Public PoC code is available on GitHub.
If you suspect your MikroTik device is vulnerable or exposed to public exploit scripts, execute the following security hardening steps immediately. 1. Update RouterOS and Firmware
The vulnerability was first reported by a security researcher, who demonstrated how an attacker could use a simple exploit to bypass authentication and gain access to the device. The exploit involves sending a malicious request to the device's web interface, which tricks the device into thinking that the attacker is a legitimate user.

The vulnerability is an authentication bypass issue that exists in the way RouterOS handles HTTP and HTTPS requests. Specifically, an attacker can exploit the vulnerability by sending a specially crafted request to the device's web interface, which would allow them to access the device without providing any valid login credentials.
