Shiomitsu of the IoT Inspector Research Lab May 5, "A few weeks ago, we published an advisory on the Cisco RV series routers, where we outlined the root cause for authentication bypass and remote command execution issues.
This week, Cisco has released an advisory for another bug we reported around the same time: A privilege escalation issue, which could be used in combination with the other two issues to run arbitrary code with root privileges on affected RV34X devices. A look at old firmware shows that the bug has been present since at least the first firmware update package of the RV34X series back in February A fix is available. The issues in question were an authentication bypass and system command injection, both in the web management interface.
These can be chained together to achieve unauthenticated command execution. A remote attacker could execute arbitrary commands or bypass authentication and upload files on an affected device. Critical Vulnerability Can Allow Attackers to Hijack or Disrupt Juniper Devices by Eduard Kovacs of Security Week April 16, A buffer size validation flaw may allow an unauthenticated remote attacker to send specially crafted packets to a vulnerable device, triggering a partial Denial of Service, or remote code execution.
An attacker who successfully exploits the vulnerability can gain root access to the targeted system. The bug is in the overlayd daemon which runs as root by default and listens for UDP connections on port The underlying problem is improper buffer size validation, which can lead to a buffer overflow.
The bug is CVE Good news: Fixes are available and vulnerable devices are typically not exposed to the Internet. Maybe its just me, but there seem to be a very very large number of security flaws in their software. Anybody with authenticated access to the router can run arbitrary system commands on the device as the system admin user, with root privileges. D-Link has released a patched firmware. No date, other than a bogus date in the future.
The vulnerability exists because the web-based management interface does not properly validate user-supplied input A successful exploit could allow the attacker to execute arbitrary code as the root user Fixes are available.
The vulnerability is one of three critical flaws fixed by Cisco on this week. The vulnerability ranks 10 out of 10 on the CVSS vulnerability-rating scale. The glitch is considered critical because an attacker - without any authentication - could remotely could exploit it This flaw, which has a CVSS score of 9. February 24, A Buffer Overflow flaw CVE allows for arbitrary code execution by a remote attacker without the password.
Fortinet fixes vulnerabilities discovered by Positive Technologies by Fortinet February 4, Until the bug is fixed they suggest enabling two-faction authentication and blocking web traffic from countries that do not need to access their devices. Then: SonicWall SMA zero-day exploit actively used in the wild by Lawrence Abrams February 1, SonicWall is still investigating the vulnerability and has not provided many details.
It likely affects their SMA series of remote access appliances. Another suggested mitigation is restricting the IP addresses than can access the SonicWall management interface. They have still not provided any details on the vulnerability. Tweets from the NCC Group indicate that it allows remote access to the management interface without authorization.
Cisco reveals critical bug in small biz VPN routers when half the world is stuck working at home by Simon Sharwood of The Register February 5, This is as bad as bad gets. The worst bugs "can be exploited by an unauthenticated, remote attacker to execute arbitrary code as the root user. All the attacker needs to do is send a maliciously crafted HTTP request to the web-based management interface. Other bugs allow a remote bad guy, again without a password, to "conduct directory traversal attacks and overwrite certain files that should be restricted All the bugs seem to be due to lazy Cisco employees who can't be bothered to validate input.
If the bugs don't turn you away from Cisco, consider the tech support experience - they put most of the burden on you. These quotes are from the bug Advisories below. You want the patches? Cisco won't tell you. You figure it out. The big point is that you pump your own gas when you are a Cisco customer. I would not use their hardware for a paper weight. Patches are available. Feb 3, Their software has too many bugs and this case shows their refusal to fix some bugs.
Cisco addressed 67 high-severity bugs. That is far too many to have in software that is reasonably mature. Far too many. Again, just one week. Below is a summary of the CISA summary for assorted devices from networking companies. They may not all be routers and the severity of the bugs vary widely. CVE Just CISA weely vulnerability summaries. D-Link VPN routers get patch for remote command injection bugs by Ionut Ilascu of Bleeping Computer December 8, No one makes money saying that newly discovered bugs are not that big a deal.
So, this trio of D-Link bugs may or may not be a big deal, despite the fact that everyone says the sky is falling. To be clear, the most critical of the three bugs is indeed the worst possible type of flaw - anyone on the Internet can totally hack these routers. What is not said, however, is whether the web interface to these routers is exposed to the Internet by default. If not, this is much less of an issue.
I suspect the web interface is not available remotely because if it was, the company that found these bugs would say so. Either way, D-Link should say something about this in their response, but, they do not. They don't care about security.
Further proof about how little D-Link cares about security is the timeline. Three bugs were reported to them on August 11, Their first response was early December They fixed two of the bugs and consider the third not a real problem.
At least on good routers they can. I don't know if these routers support VLANs. December 8, Quoting: "The vulnerable component of these devices is accessible without authentication. Note that even after 4 months, the newly released firmware is considered Beta. Walmart-exclusive router and others sold on Amazon and eBay contain hidden backdoors to control devices by Bernard Meyer of CyberNews. Quoting: "In a collaboration between CyberNews Sr.
Information Security Researcher Mantas Sasnauskas and researchers James Clee and Roni Carta, suspicious backdoors have been discovered in a Chinese-made Jetstream router, sold exclusively at Walmart as their new line of 'affordable' wifi routers. This backdoor would allow an attacker the ability to remotely control not only the routers, but also any devices connected to that network The Wavlink routers also contain a script that lists nearby wifi and has the capability to connect to those networks While Jetstream has an exclusive deal with Walmart, and is sold under other brand names like Ematic, there is very little information available about which Chinese company actually produces these products While Clee's original research and follow-up analyzed one Wavlink router, our new analysis shows that multiple Wavlink and Jetstream devices have now been shown to be affected.
In fact, all of the devices that the team analyzed were found to contain backdoors. So far, nothing. Update Nov 13, It appears that one of these articles was wrong. The Netgear router was not hacked. Two bugs were found in the Netgear router. The bugs will be disclosed to the hardware manufacturers and hopefully fixes will be released. What no one will say is whether the same bugs exist in other routers from these companies.
The bug is considered critical and is expected to come under active exploitation once proof-of-concept code is made publicly available. The underlying problem is a stack-based buffer overflow. To exploit the bug, bad guys do not need to have valid credentials.
Oh, and the bug is trivial to exploit, even for unskilled attackers. This is SonicWall's second major bug this year. This is the original research. The flaw can be triggered by an unauthenticated HTTP request involving a custom protocol handler. One bug CVE was that the firmware update process accepted software with forget server certificates. This would have let spies and hackers install their own firmware on their router.
An attacker would have to be adjacent network-wise to the router to perform this man in the middle attack, but it could result in a full compromise of the router. There are two things here that are very important, much moreso than the bugs themselves. It is very likely they too are vulnerable, but it is none of our business. Then too, there is the way Asus handled this. For one thing they never issued a security advisory.
And, as we see below in the Revision History, they could not be bothered to tell Rakhmanov when they fixed the bug. And, when he asked they were not sure if they fixed one or both bugs. The research the story is based on is for a router that is End-of-Life no more bug fixes, it's too darn old to bother with.
The bugs are in the web interface to the router, as they often are. Best practices for router security is always to limit LAN side access to the router's admin interface, and, of course, to disable remote administration.
I found one bug quite noteworthy. It lets a bad guy bypass the router password by adding a couple parameters to the HTTP request to the router.
The same flaw was reported in and again in That tells you all you need to know about D-Link. July 23, This router is EoL. Vendor Disclosure was Feb. The number of critical bugs in Cisco software over the years has been far too high.
I would not use their products. Cisco just released fixes for 34 bugs, five of which are the most critical in that they allow bad guys to get total control of vulnerable devices.
It has a default, static password that, if obtained by attackers, can lead to the full remote hijacking of a device. This is a mistake that can not be forgiven and not the first time Cisco has had hard coded passwords. This is a very common flaw, improper validation of input.
Translation: lazy programmers. Cisco Security Advisories from Cisco. Lots of bugs documented in the middle of July. Tenda AC15 AC Vulnerabilities Discovered and Exploited by Sanjana Sarda of Independent Security Evaluators July 10, Their research uncovered five bugs including two methods attackers can use to gain persistent unauthenticated root access to the router.
They also found 7 open LAN side ports. Much of this article is focused on the specifics on the bugs and it leaves out the implications. Does a user have to be logged in to exploit the bug or not? Despite this, the article is very useful at the end. ISE first contacted Tenda in January Here, six months later, no response from Tenda at all. And, as always with router bugs, it is likely that similar flaws exist in other firmware versions and other Tenda routers.
The article adds some context to the story but does not clarify the nature of the bugs. The vulnerability, which allows for remote code execution, has been present in the R since it was released in But that is only the beginning. Adam was able to identify 79 different Netgear devices and Netgear firmware images that included the buggy code.
The oldest buggy firmware dated back to The vulnerability was reported to Netgear on May 7, and they seemed to have ignored it. Using assorted scripts, Adam created an exploit for each of the buggy firmware images. Then, he tested his exploit on 28 of the vulnerable devices to ensure that it worked as expected. Discusses two defenses, the obvious one being turning off remote administration. Netgear just released hotfixes for two of the routers.
The article has the full list of 79 vulnerable models. June 18, 79 Netgear router models risk full takeover due to unpatched bug by Lawrence Abrams of Bleeping Computer June 18, The proof of concept exploit at Github.
It is a Python script that starts the telnet daemon as root listening on TCP port and not requiring a password to login. June 15, Looks to be a similar bug to the above. Maybe the same? Can't tell as this has no technical details. The interesting thing here, to me, is how Netgear ignored the bug report for six months.
Living on a prayer? Netgear not quite halfway there with patches for 28 out of 79 vulnerable router models The Register June 30, However, on the website for European countries, the status is "End of Sale" which means that it can no longer be purchased but it is still supported by the vendor.
Now, over three months later, D-Link released beta firmware that fixes three of the six flaws. Two bigger issues: 1 What about other models? Unit 42 warned that newer routers may be vulnerable to the same flaws because they share a common code base. A good router vendor will check for the same flaw in all their products. A bad router vendor will not.
The response from D-Link said nothing about any other models. Why is Unit 42 even looking at ancient consumer devices? No date. Multiple Vulnerabilities in Wavlink Router leads to Unauthenticated Remote Code Execution by James Clee April 18, Clee started a new hobby - buying cheap Chinese technology to see what he could find out about security. He found back doors and miserable password verifications. This is not a company you want to deal with.
They were just as bad as the router. He found that lots of web pages are externally accessible without authentication and they contain sensitive data.
He could get the username and password without authenticating to the devices. Once again, Wavlink did not respond to any of his attempts at communication. An article on this page above from November , expands on this. It is not just one Wavlink router with a backdoor.
New analysis by Clee and others found that multiple Wavlink and Jetstream devices are affected. Sophos learned about the problem on April 22nd when a customer reported something strange. They published an emergency security update on April 25th. The firewalls can self-update, though I doubt every user has that enabled. No surprise to learn that vulnerable firewalls had either their administration or User Portal control panel exposed to the Internet.
The bug let bad guys steal files from the XG firewall, and those files could include usernames and hashed passwords for the firewall administrator, for the firewall portal admins and for user accounts used for remote access to the device. Bad guys could also learn the firewall's license and serial number, and see some user emails.
Sophos researchers named the malware Asnarok. From what I have seen, the Sophos response was great. You could not ask for more. Not only did they fix the bug quickly, they also documented the heck out of the issue. An extensive explanation of the problem. Asnarok Trojan targets firewalls from Sophos April 26, More detailed explanations. In addition, the opkg unpacker is buggy; malformed data leads to a variety of memory violations. One of the bugs was introduced in February Security Now!
They first observed this in early December There are two different zero-day flaws in three DrayTek Vigor devices, the , and B. The bugs could allow for arbitrary code execution on a vulnerable system.
This could allow an attacker to eavesdrop on network traffic, operate SSH and Web based backdoors, and create system accounts. One flaw is in the login mechanism and it allows attackers to hide malicious code inside the router's username field. This malicious code can grant the hackers control over the router. Next, the attackers started recording traffic coming to port 21 FTP , 25 email , email and email.
These are four very old protocols and they still use plain text. It is assumed the attackers were looking for FTP and email passwords. The second flaw is in the "rtick" process and attackers used it to create backdoor accounts on the hacked routers. Qihoo says that around , vulnerable DrayTek devices are online.
DrayTek issued updated firmware six days after they learned of the problem. This is rare, vendors usually fix only the devices with the reported problem. April 3, The devices are seven modem-router gateways, odd routers including some Nighthawk and Orbi models and one range extender. The worst of the flaws lets attackers remotely install malware on one router. A "pre-authentication command injection security vulnerability" on five routers could also lead to total network takeover. For a number of the flaws Netgear has not provided specific details.
Does your Netgear router need an update? Turns out, this is a hard question to answer. Netgear does a terrible job of communicating to its customers what each router's model number is. They hardly ever use the actual model number in their consumer marketing and packaging.
To find the model number, turn the device over and look at the sticker on the bottom. The update procedure differs among the various routers. The article has a full list of the buggy router model numbers. This has no information about the bug at all. This too has no information at all about the flaw. Adds some perspective: "Netgear has a long history of patching command injection flaws dating back to Good news: it is not easy to exploit the bug.
Bad news: In the US, this will never be fixed. ISPs are virtual monopolies and thus have no reason to do a good job. Fixing this takes time, effort and money and few very customers will ever learn about it. I tried to get a response from Spectrum, it was a waste of time. The company that found the flaw offered a tester script for Linux that seems useless. They also offered some JavaScript that can copied and pasted into a browser console to test if your Internet box is vulnerable.
And, you may need to change the port number, which is why I suggest using nmap below. Netgear only offers free tech support for the first 90 days, so I can not ask them about this. What to do? I suppose you could try and learn the firmware version that your modem or gateway is running and then try to find out if it has been patched for the Cable Haunt flaw.
In the US, this is almost definitely a waste of time. First, see if your Internet box uses Broadcom. If not, you are safe. The Toms Guide article below has links to pages that show this for Arris and Netgear devices.
For other companies see approvedmodems. If that fails, perhaps look for the technical specs of your modem or gateway. Maybe try to contact the hardware manufacturer. If Broadcom If you have a router and a modem as stand-alone devices, run the same nmap against The buggy Spectrum Analyzer looks like this on a Netgear modem. Found a Spectrum Analyzer? If so, nag either your ISP or the hardware vendor for fixed software.
Lotsa luck probably won't happen. Better yet, block access to the buggy device. For more, see the Security Checklist page here, the section on Local Administration. If you have a router and a modem as separate devices, you need a nerd to configure a defense.
One option is something called a static route - some routers let you configure this, some do not. If your router supports firewall rules rare , see my blog below about creating an outbound firewall rule to block modem access.
Cable Haunt vulnerability tests by Lyrebirds Jan. Broadcom released fixed software to their customers ISPs and hardware vendors in May When asked if the updated software was widely deployed, Broadcom had no comment. The article has links to web pages that show where Internet boxes are using Broadcom or not.
See Arris and Netgear. Using a router to block a modem by me in If your router provides outbound firewall rules, it can block LAN side access to a modem which offers perfect protection.
