Thousands of Juniper firewalls are open to serious attack

A month after a patch was released, an overwhelming majority of Juniper’s SRX firewalls and EX Series switches remain vulnerable to a group of flaws which, when combined, can result in remote code execution, according to threat intelligence platform provider, VulnCheck.

In its findings, The Register reports, VulnCheck says that on August 17, Juniper announced finding, and patching, five separate vulnerabilities affecting all versions of Junos OS on SRX firewalls and EX Series switches. 

These vulnerabilities are now tracked as CVE-2023-36844, CVE-2023-36845, CVE-2023-36846, CVE-2023-36847, and CVE-2023-36851. While individually they carry a 5.3 severity rating, collectively they earned a 9.8 score and have been deemed critical. Some researchers say that by chaining these five, threat actors are able to achieve remote code execution, which could lead to a whole host of other issues, such as malware deployment. Other researchers believe that chaining just some will suffice.

Exploiting known flaws

Now, a month later, roughly four in five (79%) public-facing Juniper SRX firewalls and EX Series switches are yet to be patched up and remain vulnerable to these flaws. To make matters worse, more than ten days ago Juniper updated its security advisory to say it observed threat actors attempting to exploit these flaws. 

According to numerous research, hackers are more inclined towards abusing older, known flaws, rather than trying to discover their own zero-day vulnerabilities. That is because older flaws already have proof-of-concepts and are easily exploited, especially knowing that many firms aren’t that diligent when it comes to applying patches and upgrades.

To remain secure, businesses are advised to apply new fixes and patches as soon as they roll out or to have a solid patching schedule to adhere to. 

If you’re unsure whether or not your firewall is vulnerable to CVE-2023-36845, VulnCheck has released a free scanning tool which you can find on this link.

The latest Apple TV 4K test lets you watch four sports streams at once

Apple is trying something new with the latest beta version of tvOS 16.5: the option to watch up to four simultaneous streams at once. Right now it's limited to live sports streamed through the Apple TV app on the Apple TV 4K , specifically MLB Friday Night Baseball and the MLS Season Pass. A multi-view option was spotted in the tvOS software last month, but the code was hidden and not enabled. MacRumors reported that the feature would be enabled this weekend, and beta testers have since been able to use it. As yet multi-view hasn't been officially announced by Apple, but it's expected that tvOS 16.5 is going to be pushed out in its final form within the next month or so. WWDC 2023 is around the corner as well, when we should be hearing about the next major updates for Apple's various operating systems – including tvOS 17. How it works Over at 9to5Mac there's a hands-on demonstrating how the multi-view feature works, and it's pretty much as you would expe...

Garmin's new radar-equipped tail light will keep you safe on your e-bike

Garmin's Varia bike radars are some of the most popular pieces of cycling tech around – and now the company has delivered its first rearview radar to have been specially designed for some of the best e-Bikes .   Garmin's Varia range mounts to the back of your bike and broadcasts a radar signal behind you, so you can get visual and audible alerts when something's overtaking you. Even better, the new Varia eRTL615 plugs directly into most e-bikes, with no battery required. Because the catchily-named Varia eRTL615 is also a tail light, it'll also make sure you're visible to other vehicles too, promising to emit a flashing or solid light that's visible from up to a mile away in daylight. To connect Garmin's new radar tail light to your e-bike, you'll need to pick the right Garmin adapter cable (which isn't included). You can buy power cables compatible with Bosch, Shimano, or USB-A terminals or connections, with more info on those available on Garmin...
