Critical Vulnerability in WinRAR Exposed – Absolute Path Traversal

According to a report this morning from SonicWall, a vulnerability that could allow remote code execution has been discovered in WinRAR. This software vulnerability exposes the half a billion users of this Windows unarchiver. The vulnerability exploited is detailed by MITRE in CVE-2018-20250.

To find out if you are vulnerable, check to see if your WinRAR version is anything prior to WinRAR prior to 5.70 beta 1.

The fix is to update your software to the latest WinRAR version to resolve the issue.

For those not familiar with WinRAR, according to Wikipedia, “WinRAR is a trialware file archiver utility for Windows, developed by Eugene Roshal of win.rar GmbH. It can create and view archives in RAR or ZIP file formats, and unpack numerous archive file formats. To enable the user to test the integrity of archives, WinRAR embeds CRC32 or BLAKE2 checksums for each file in each archive. WinRAR supports creating encrypted, multi-part and self-extracting archives.”

Update: According to a March 23 2019 report by SonicWall, this WinRAR vulnerability is now being exploited in the wild.

“There have been two major exploits of this vulnerability, one targeting Ukraine with an Ukrainian law related PDF document and another targeting users in the Middle East. Last week, SonicWall Capture Labs Threat Research team has observed another campaign targeting users in Chile. WinRAR vulnerability is the most sought after exploit used by both cyber criminals and nation state actors.”

The security news brief from SonicWall also details the infection cycle of a WinRAR exploit. Be on guard!

I’ve found a great tool (isearchfrom.com) recently that emulates the Google search location. You have to enter the country where you search from, the language and you can even specify the device. Then you enter the words you are searching for and click on Search. You will get exactly the same search results if you were in the specified country.

What is it good for?

If you work on SEO and want people to find your website not just in your country, but in other countries as well, then you can check the Google search result position in the different countries.

Your Internet May Be Going Down Because Norton ConnectSafe Is Retiring

Hello, World! Your Internet connection may be going down this November 15, 2018 onward if your devices are connected to the internet via Norton ConnectSafe’s DNS IP addresses and you do not have a secondary DNS in place. The announcement is currently displayed at https://connectsafe.norton.com/configureRouter.html with a link to this FAQ that hopefully will answer most of your questions.

The DNS IP Addresses you need to check for and change from are any pair among the following:

  • 199.85.126.10
  • 199.85.127.10
  • 199.85.126.20
  • 199.85.127.20
  • 199.85.126.30
  • 199.85.127.30

If you changed your DNS, you probably know already which one you want to go to next. If you have no idea and need some time to investigate, you can either remove the DNS settings that you have in your device (computer or mobile device) and therefore default to your Internet Service Provider’s DNS settings or you can temporarily follow this How-To Geek article that offers step by step instructions on how to change your DNS to OpenDNS’ or Google’s if you trust these two tech companies.

Alright, you are now in the know, friend!

And That Is How Your TV Is Watching You

Have you ever heard of the term “idiot box?” Maybe they are not that dumb? Smart TV’s are able to watch you watch TV and learn about the devices on the same network in your home. By the way, even if you had never heard of the idiot box term, I am sure you can easily guess that it is the North American word for a television set. At least, that is what Google seems to believe.

idiot box definition by Google

In fact, search of “define idiot box” yielded the definition “a television set.” Marriam-Webster seems to agree as well.

Back to our point, though. Your Smart TV has been reported to spying on you with your consent but, if you are like the majority of Smart TV owners, without your knowledge. So, go ahead and read up on these stories about what Samba TV does with your data and what bad hackers could trick your device into doing. Armed with this knowledge, you will at least be able to understand how in the world did that company know to advertise this or the other product to you.
