A retro-computing enthusiast found a MikroTik RB133 (32MB RAM, PowerPC CPU) running RouterOS v5.22 in an old telecom rack. Modern PCs with Winbox 3.41 would disconnect every 60 seconds. Winbox 2.2.18 held stable sessions for days, enabling the user to extract configuration scripts and learn early RouterOS quirks.

For a legacy utility, Winbox 2.2.18 packed a surprising amount of functionality that remains the standard for MikroTik management today.

Winbox uses a proprietary protocol to communicate with the router. In older versions (including the 2.2.x series), this protocol had documented vulnerabilities where authentication data was not handled as securely as it should have been.
