This high-severity flaw affects MikroTik RouterOS stable versions before and long-term versions through 6.48.6 .
Security researchers cracked the vulnerability by reverse-engineering the RouterOS binary files and analyzing the custom network protocols used by MikroTik.
: It allows an authenticated user with "admin" rights to escalate to "super-admin" via the Winbox or HTTP interfaces. Never expose management interfaces (Winbox 8291, Webfig 80,
Never expose management interfaces (Winbox 8291, Webfig 80, SSH 22) directly to the internet. Create firewall rules to only allow access from trusted IP addresses.
The vulnerability lies within the management interfaces of RouterOS, primarily affecting the WinBox and WebFig services. Attackers exploit a flaw in how the system processes specific network requests during the authentication handshake phase. Attackers exploit a flaw in how the system
