The vulnerabilities impact Mikrotik RouterOS firmware versions before 6.42.7 and 6.40.9.

CVE-2018-1156-A stack buffer overflow flaw that could allow an authenticated remote code execution, allowing attackers to gain full system access and access to any internal system that uses the router.The technique is yet another security blow against MikroTik routers, which was previously targeted by the VPNFilter malware and used in an extensive cryptojacking campaign uncovered a few months ago.īesides this, Tenable Research also disclosed additional MikroTik RouterOS vulnerabilities, including: After RouterOs / Routerboard reboot IPv6 menu appearance in Winbox. All Winbox interface functions are as close as possible mirroring the console functions, that is why there are no Winbox sections in the manual. It is a native Win32 binary but can be run on Linux and macOS (OSX) using Wine.
In other words, the new exploit could allow unauthorized attackers to hack MikroTik's RouterOS system, deploy malware payloads or bypass router firewall protections. Winbox is a small utility that allows the administration of MikroTik RouterOS using a fast and simple GUI. However, the new attack method found by Tenable Research exploits the same vulnerability and takes it to one step ahead.Ī PoC exploit, called " By the Way," released by Tenable Research Jacob Baines, first uses directory traversal vulnerability to steal administrator login credentials from user database file and the then writes another file on the system to gain root shell access remotely.
New Hack Turned 'Medium' MikroTik Vulnerability Into 'Critical'

RouterOS user database security will be hardened, and deciphering will no longer be possible in the same manner. What to expect in the coming hours/days: Updated RouterOS versions coming ASAP. Include your LAN, and the public IP that you will be accessing the device from. As an alternative, possibly easier, use the “IP -> Services” menu to specify “ Allowed From” addresses. We suggest this to become common practice. It is best, if you only allow known IP addresses to connect to your router to any services, not just Winbox.
What do do: 1) Firewall the Winbox port from the public interface, and from untrusted networks. The log may show unsuccessful login attempt, followed by a succefful login attempt from unknown IP addresses.
#Winbox v6.28 password
If your Winbox port is open to untrusted networks, assume that you are affected and upgrade + change password + add firewall. Edit: v6.42.1 and v6.43rc4 have been released!Īm I affected? Currently there is no sure way to see if you were affected. Updated versions in all release chains coming ASAP. Versions affected: 6.29 to 6.43rc3 (included). How it works: The vulnerability allowed a special tool to connect to the Winbox port, and request the system user database file.
