A known vulnerability in MikroTik routers is potentially far more dangerous than previously thought. A cybersecurity researcher from Tenable Research has released a new proof-of-concept (PoC) RCE attack for an old directory traversal vulnerability that was found and patched within a day of its discovery in April this year. The vulnerability, identified as CVE-2018-14847, was initially rated as medium in severity but should now be rated critical because the new hacking technique used against vulnerable MikroTik routers allows attackers to remotely execute code on affected devices and gain a root shell. The vulnerability impacts Winbox—a management component for administrators to set up their routers using a Web-based interface—and a Windows GUI application for the RouterOS software used by the MikroTik devices. The vulnerability allows 'remote attackers to bypass authentication and read arbitrary files by modifying a request to change one byte related to a Session ID.'

New Hack Turned 'Medium' MikroTik Vulnerability Into 'Critical' However, the new attack method found by Tenable Research exploits the same vulnerability and takes it to one step ahead. A PoC exploit, called ',' 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.

In other words, the new exploit could allow unauthorized attackers to hack MikroTik's RouterOS system, deploy malware payloads or bypass router firewall protections. The technique is yet another security blow, which was previously targeted by the and used in an extensive uncovered a few months ago. New MikroTik Router Vulnerabilities Besides this, Tenable Research also additional MikroTik RouterOS vulnerabilities, including: • 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. • CVE-2018-1157—A file upload memory exhaustion flaw that allows an authenticated remote attacker to crash the HTTP server. • CVE-2018-1159—A www memory corruption flaw that could crash the HTTP server by rapidly authenticating and disconnecting.

• CVE-2018-1158—A recursive parsing stack exhaustion issue that could crash the HTTP server via recursive parsing of JSON. The vulnerabilities impact Mikrotik RouterOS firmware versions before 6.42.7 and 6.40.9. Tenable Research reported the issues to MikroTik in May, and the company addressed the vulnerabilities by releasing its RouterOS versions 6.40.9, 6.42.7 and 6.43 in August. While all the vulnerabilities were patched over a month ago, a recent scan by Tenable Research revealed that 70 percent of routers (which equals to 200,000) are still vulnerable to attack. The bottom line: If you own a MikroTik router and you have not updated its RouterOS, you should do it right now. Also, if you are still using default credentials on your router, it is high time to change the default password and keep a unique, long and complex password.

All Winbox interface functions are as close as possible to Console functions, that is why there are no Winbox sections in the manual. Some of advanced and system critical configurations are not possible from winbox, like MAC address change on an interface. Starting the Winbox Winbox loader can be downloaded directly from the router or from the. When downloading from the router, open a web browser and enter router's IP address, RouterOS welcome page will be displayed. Click on the menu item that says Winbox to download winbox.exe. Note: Neighbor discovery will show also devices which are not compatible with Winbox, like Cisco routers or any other device that uses CDP (Cisco Discovery Protocol) Description of buttons and fields of loader screen • [.] - discovers and shows MNDP (MikroTik Neighbor Discovery Protocol) or CDP (Cisco Discovery Protocol) devices.
