The technique is yet another security blow against the MikroTik router family. Previous hacks have left the routers open to device failures, cyptojacking and network eavesdropping. Tenable Research says it has found a new attack technique that exploits the same bug CVE that allows for unauthenticated remote code execution.
The underlying flaw is tied to a Winbox Any Directory File that allows threat actors to read files that flow through the router without authentication. The new technique, found by Jacob Baines, researcher at Tenable Research, goes one step further allowing an adversary to write files to the router.
Baines also created a proof of concept of the attack outlined Sunday. The sprintf is used on the following string:. This is as bad as it gets, Baines told Threatpost. It uses CVE to leak the admin credentials first and then an authenticated code path gives us a back door.
While MikroTik patched CVE in early August, a recent scan by Tenable Research revealed only approximately 30 percent of vulnerable modems have been patched, which leaves approximatelyrouters vulnerable to attack. The read version of the vulnerability is currently being exploited by a number of different campaigns. In August, it was reported 3, MikroTik routers were being abused in a cyptojacking campaign. Tenable researcher Baines said he is not aware of the technique being exploited in the wild.
The vulnerabilities include a stack buffer overflow vulnerability CVEa file upload memory exhaustion CVEa www memory corruption CVE and a recursive parsing stack exhaustion CVE Seven new modules discovered in VPNFilter further fill in the blanks about how the malware operates and reveals a wider breath of capabilities.

Over 25, servers globally are vulnerable to the critical Citrix remote code execution vulnerability. The vulnerability CVEwhich Threatpost reported on in December, already packs a double-punch in terms of severity: Researchers say it is extremely easy to exploit, and affects all supported versions of Citrix Gateway products and Citrix ADC, a purpose-built networking appliance meant to improve the performance and security of applications delivered over the web.
A patch will not be available until late January, Citrix has announced. That leaves various systems worldwide open to the flaw — and now, with PoC exploits available on GitHub, researchers expect exploit attempts to skyrocket.
This PoC was similar to the first, except it was written in Python and established a reverse shell. In addition, researchers have also released scanners and honeypots to see if various servers are vulnerable to CVE Citrix did not disclose many details about the vulnerability in its security advisoryhowever, Qualys researchers said that the mitigation steps offered by Citrix suggest the flaw stems from the VPN handler failing to sufficiently sanitize user-supplied inputs.
According to the Bad Packets Report, over 25, servers globally — with the most in the U. A patch will be released on Jan.

On systems where the patch addressed by Microsoft can't be installed, mitigation measures are still available to block BlueGate exploitation attempts.

MikroTik now provides hardware and software for Internet connectivity in most of the countries around the world. RouterOS is the operating system of most Mikrotik devices. The vulnerability affects all versions of RouterOS from 6. First things first, we had to see which binaries was changed before and after the patching. RouterOS is written on top of Linux Kernel so a lot of kernel modules will be different in each version. What we did was downloading RouterOS 6.
Mikrotik Router - Denial of Service
I hashed every file inside those packages to see the difference, and long behold I found a few. As you can see, mproxy binary has changed.
Which makes sense because mproxy binary handles all Winbox requests. So, how can we confirm this? It shows an easy way to get a bash shell inside a RouterOS and copy additional binaries to its filesystem.
So we added a new and big BusyBox in addition to a gdbserver to do the job for us. It was pretty easy on VM since all you need to do is mount RouterOS vmdk somewhere and add additional files. First, we turn off secure communication between the Router and Winbox just because we can! Interestingly, this approach has had more than a couple security flaws. Just think about it, you download an unknown DLL from a remote host and you run it under Winbox, a signed executable!
Right now, we want to switch off this list with our crafted string.
New Exploit for MikroTik Router WinBox Vulnerability Gives Full Root Access
First Winbox authenticates with the Router and then tries to get the list file. Pretty safe, right? But we noticed something interesting. A single byte is changing each time we send the same request to the Router, and each time we sent that exact same byte over to the Router in our next request.Peg tube backflow
Session ID? So we did our repeat attack with this tiny modification. We sent the request, waited for the Router to respond, switched that one byte by the byte received from the response, and then we sent the second request. We got our file!! Just by sending the highlighted packets in the right order and switching the byte, the Router folds. Trust your own service to do proper validation :. Now we can read ANY file from the Router! Which files are useful? In our previous talk on APA3 conference, we talked about just how insecure Mikrotik is, especially when it comes to handling credentials.
In short, Mikrotik uses a very weak encoding no hash and salt to store passwords to an index file. In addition to all this, Mikrotik saves your passwords in easily decryptable ciphers as you saw in the PoCwhich might have an effect on your entire network infrastructure. For example, SNMP passphrases are usually shared across multiple network devices including the Mikrotik router. Posts Tags Categories.All new content for Exploit Database.
Mikrotik Router - Denial of Service. EDB-ID: CVE: EDB Verified:. Author: PoURaN. Type: dos. Platform: Hardware. Date: Vulnerable App:. That happens for about 5 minutes. After the 5 minutes, winbox is stable again, being able to accept new connections. The "other actions" depends on the router version and on the hardware. For example on Mikrotik Router v3. This script, offers you the possibility to download any of the dlls that can be downloaded from the router one-by-one or alltogether!
The file must be contained in the router's dll index. The dlls downloaded, are in the format of the winbox service. You can download ALL the files of the router's dll index using the following command: python mkDl.
It is a MUST for remote routers when they are in long distance many hops to use a slower speed 9 for example. Also in the beginning of the dlls file list, script shows you the router's version provided by router's index 2.
You can download a specific. You can cause a Denial Of Service to the remote router. Means denial in winbox service or more read above for more python mkDl. The script is requesting the file till the router stops responding to the port Then it waits till the service is up again using some exception handlingthen it requests again till the remote service is down again etc etcSetelah saya cek konfigurasi DNS, alangkah kagetnya karena DNS yang semula memakai DNS saya sendiri tiba-tiba berubah menjadi DNS yang tidak saya kenal, lalu saya cek log, dan hasilnya mencengangkan lihat gambar di bawah.
Dari screenshoot diatas bisa dilihat ada log yang tertulis " dns changed by admin ", yang artinya konfigurasi DNS diubah oleh user admin, user tersebut memang hanya saya dan rekan satu tim saja yang tahu, namun masalahnya bukan itu, kalau diperhatikan dengan teliti, user admin tersebut login dari alamat IP asing yaitu Tentu saja alamat IP itu bukan berasal dari network saya, setelah saya lookup ternyata alamat IP tersebut berasal dari china, artinya adalah? Akhirnya case ini saya posting di group facebook mikrotik indonesia, ternyata, saya tidak sendirian, banyak member lain disana yang juga mengalami hal yang sama dengan saya, berdasarkan jawaban yang diberikan oleh member lain, bahwa pada beberapa versi routeros mikrotik terdapat bug pada service www yang digunakan untuk service webfig, yaitu service yang memungkinan kita mengkonfigurasi router mikrotik melalui web browser.
The new Hajime variant has been scanning wide range of tcp ports since Now it scans 80, 81, 82,and We observe these scanning activities at out honeypots.
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, 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. However, the new attack method found by Tenable Research exploits the same vulnerability and takes it to one step ahead. Tenable Research reported the issues to MikroTik in May, and the company addressed the vulnerabilities by releasing its RouterOS versions 6.
While all the vulnerabilities were patched over a month ago, a recent scan by Tenable Research revealed that 70 percent of routers which equals toare still vulnerable to attack. 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.
