You can now get MikroTik training direct from Manito Networks. Mikrotik routers straight out of the box require security hardening like any Arista, Cisco, Juniper, or Ubiquiti router. Some very basic configuration changes can be made immediately to reduce attack surface while also implementing best practices, and more advanced changes allow routers to pass compliance scans and formal audits. This is a typical branch office configuration with Inside, Outside, and Management network "zones".
The Management network isn't strictly necessary in organizations without applicable compliance requirements but it's a best practice. For organizations that do have compliance standards in place, having a separate management network statisfies Infrastructure Router STIG Finding V The network devices must only allow management connections for administrative access from hosts residing in the management network.
The first step we'll take is disabling any physical network interfaces that aren't in use, denying an intruder access to the device if they somehow got into the wiring closet or server room.
To plug into the router they'd have to disconnect a live connection and draw attention. First list all the interfaces, making note of the numbers associated with each interface refer to the table above for the interfaces in this exercise :. Then shut off all the interfaces that aren't live so they can't be used to access the device.
In our case interfaces 1, 2, and 3 are in use, and we're not using interfaces 4 and Once your network interfaces have been secured and the rest of this guide is complete also take a look at segment your networks with VLANs. Next we'll do an Nmap scan of the stock router from the WAN side to get a baseline of open ports and services.
This will our starting point, shown below:. If you want to learn more about using Nmap check out the Network Scanning With Nmap write-up that will get you going. The relevant portions of the port scan output are shown in the following sections. For any port scan we pay particular attention to the open ports that are found, and the services that are running on those ports. Knowing your basic ports and protocols is very helpful when looking at port scan results, spend some time learning them if you haven't already.
Nmap found a number of issues, and it's clear we have some work to do. The router is running multiple unencrypted protocols, and services that aren't necessary at all. We also see the result of using the factory default credentials. If this router was connected to the Internet just like it is right now it would almost certainly be exploited shortly after coming online. Like in most production networks we assume the router will only be administered through SSH and Secure-mode Winbox. Both SSH and Winbox sessions are encrypted so we don't have to worry about plaintext information leaking.
First we'll view running services on the router then shut off all services except SSH and Winbox.

Lastly we'll scan again, just to make sure the changes are in place. Verify that the basic services have been disabled shown with an "X" by the service name by running the following:. These are used to give administrators access to a router without an IP address assigned, but by default are turned on and running on ALL interfaces - even WAN interfaces. A user inside your LAN could connect to the device via one of the MAC services, and that access needs to be restricted both from internal and external networks.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

See the PDF for more info not updated. To simplify extraction you can use:. Pay attention to set execution permissions, or your router will stuck on boot and you will have to restore the firmware!
This example enables a persistent telnet server on port In a shell:. Only RGB Bitmap 24 bit not compressed files are supported. Max size: px width, 76px height You can find a sample here. This is a reverse engineering of leaked CIA documentation. There is no chimay-red. Thanks to Content-Length and alloca macro we can control the Stack Pointer and where the post data will be written.
If we send a Content-Length bigger than KB to socket of thread A, the Stack Pointer will point inside the stack of another thread B and so the POST data of thread A will be written inside the stack of thread B in any position we want, we only need to adjust the Content-Length value. So now we can write a ROP chain in the stack of thread B starting from a position where a return address is saved.
When we close the socket of thread B, the ROP chain will start because the function that is waiting for data will return but on our modified address. Then we return to "dlsym" function present in the PLT passing as argument the address of just created string "system" to find the address of "system" function.
DEP is disabled on this version of www, so I can execute the stack.
A small ROP 3 gadgets find the address of a location on the stack where I put the shell codeand then jump to that address. At this point I can launch the syscall execve to execute my bash command.
I have no time to test all RouterOS versions. On all stable version i tested 6. Maybe on all bugfix version my tool is not working not verified.MikroTik, a Latvian hardware manufacturer, products are used around the world and are now a target of a new propagating botnet exploiting vulnerabilities in their RouterOS operating system, allowing attackers to remotely execute code on the device. Such devices have been making unaccounted outbound winbox connections. It is believed this botnet is part of the Hajime botnet.
The concern is that this new botnet will be leveraged to launch DDoS attacks. This is another event demonstrating the struggle for control between various bot-herders. RouterOS supported by MikroTik and its user community, providing a wide variety of configuration examples. The worm has a highly efficient propagation mechanism by aggressively scanning for port in order to identify publicly available Mikrotik devices and using the password cracking capabilities to infect neighbor devices.
Remote attackers exploiting this vulnerability can execute code on the system. As the overflow occurs before authentication takes place, an unauthenticated remote attacker can easily exploit it. An unauthenticated, remote attacker craft a POST request to write data to an arbitrary location within the web server process, resulting in a denial-of-service condition or the execution of arbitrary code. Logarithmic scale.
After near-zero activity for months, Radware witnessed over 10, unique IPs hitting port in a single day. Figure 3: Distribution of unique IPs scanning for the vulnerability. The worm aggressively scans the Internet with SYN packets to portbut it never actually establishes a 3-way handshake on that port, e.
It appears the worm utilizes this stealth-SYN scan method to quickly identify vulnerable Mikrotik devices, as this port is used almost exclusively by the Mikrotik RouterOS platform. In addition to scanning portthe worm targets the following ports: 80, 81, 82, The worm uses the ChimayRed exploit targeting vulnerable web servers on Mikrotik devices. The worm will try to send the malicious payload to port 80 as well as other ports described earlier 80 81 82 It seems like they opened some devices via the http port quite an old firmware and they tried to spread or access by brute forcing mikrotik neighbors.
This means that the worm utilizes exploits as well as password brute-forcing attempts to nearby neighbors, speeding up the infection rate.

Ports are unsigned bit integers that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services.
Well Known Ports: 0 through Registered Ports: through TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent.
UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP the Internet Protocol and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery.
This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. For more detailed and personalized help please use our forums. Port Details known port assignments and vulnerabilities. SG security scan: port All rights reserved.

Broadband Security.The Bandwidth Tester can be used to measure the throughput to another MikroTik router either wired or wireless and thereby help to discover network "bottlenecks". Please review the TCP protocol for details on its internal speed settings and how to analyze its behavior.
Statistics for throughput are calculated using the entire size of the TCP data stream. As acknowledgments are an internal working of TCP, their size and usage of the link are not included in the throughput statistics. Therefore this statistic is not as reliable as the UDP statistic when estimating throughput.
To see the maximum throughput of a link, the packet size should be set for the maximum MTU allowed by the links which is usually bytes. There is no acknowledgment required by UDP; this implementation means that the closest approximation of the throughput can be seen.
Warning: Up to RouterOS version 6. Bandwidth Test uses all available bandwidth by default and may impact network usability. Note: Bandwidth Test uses a lot of resources. If you want to test real throughput of a router, you should run bandwidth test through the tested router not from or to it. To do this you need at least 3 routers connected in chain: the Bandwidth Server, the router being tested and the Bandwidth Client.

The log may show unsuccessful login attempt, followed by a succefful login attempt from unknown IP addresses. What do do : 1 Firewall the Winbox port from the public interface, and from untrusted networks. It is best, if you only allow known IP addresses to connect to your router to any services, not just Winbox. We suggest this to become common practice. RouterOS user database security will be hardened, and deciphering will no longer be possible in the same manner.
You do not have the required permissions to view the files attached to this post. No answer to your question? How to write posts. That is really scary. Maybe having port-knocking needed for connection and then lifetime as long as established. Web interface is a no no from external.
This sequence can be changed by the admin but can be not disabled. Once logged in, with Winbox, the admin can regenerate a new sequence in the router for the Winbox profile for that specific account.
This new sequence is visible in the router and in the profile in Winbox. This can also be forced totally hidden so that a reset of the router is needed to go back to the sequence on the router label. A new sequence is enforced from the next time connecting. A problem with sequence portknocking is, that ports also can be used by the router. One way is not to use different ports but different times in the sequence for the packets.
Maybe easier is to have port as attention port for knocking and any knock on a port from the same source IP is not for normal firewall processing but for gaining access.
