  • Early this year, a few vulnerabilities impacting inside-CPU code were announced.

    While there is not a full disclosure available to us at present time, we can tell a few things now.

    First, not all of the vulnerabilities are limited to x86 architecture. The ARM architecture is impacted as well.

    While keeping this brief and understandable, the nature of announced vulnerabilities (CVE-2017-5753, CVE-2017-5715, CVE-2017-5754) lies in the problems connected with a few techniques used inside of the CPU.

  • User Modules are now available on Engineering Portal.

    As you probably know, User Modules are kind of a unique way how the functionality of router devices running Conel OS can be extended.

    Well, it is not that unique that you can extend functionality of your device. But it is not common that you have a range of UM ready. It is also not that common that you have a multi-language SDK with examples available so that you can create your own User Modules. Last but not the least, our services always included ...

    The structure we chose to present the products is coming from the generation of the device. Right now, we are supporting three generation of devices:
