Conel OS 6.1.10 released


Written by Jan Otte on Wednesday 3 July 2019 in the category Release with the tags , .

  • Be the first to comment
  • New version of firmware for our routers is available on Engineering Portal.

    This is a maintenance release and we expect it to be the last in the 6.1.x FW line.

    All of our routers (without exceptions requiring operator's certification) are produced with 6.1.10 from today. Other models will continue once the certification is done.

    As usual, 6.1.10 brings a line of fixes and improvements on board. Just to point out some:

    • Brute-force login attack blocking mechanism.
    • Dynamic execution time for automatic update.
    • Support for encrypting configuration backup.
    • Support for OpenVPN Management Interface (configurable).
    • Several fixes for cellular.
    • SACK vulnerability ...

    Security Advisory - SACK vulnerability


    Written by Jan Otte on Thursday 20 June 2019 in the category Default with the tags , .

  • Be the first to comment
  • This security advisory is a reaction on the recently discovered network vulnerabilities in Linux kernel (see below on particular names and links).

    These vulnerabilities can, under certain circumstances, be used by an attacker against a range of our routers running current firmware (6.1.9) with the potential result of the router rebooting.

    We have already prepared a patch which closes the vulnerabilities. The patch will be included in future firmware versions (6.1.10, 6.2.0) when these are released.

    Until the new firmware versions are available, you may apply any of the recommended workaround. The easiest ...

  • Be the first to comment
  • New version of firmware for our routers is available on Engineering Portal.

The NAM market models mentioned above can obtain the firmware via manual upgrade from EP if needed. Details of default FW versions can be found in the Firmware Distribution overview document.

    It for sure contains usual load of fixes and security updates, but next to that, there are a few ...

  • An official way how to build and install a node is using npm command. However it is not possible to find it on our routers as router is embedded device with limited resources and some nodes require complex building environment and high performance because of other languages than JavaScript.

    Fortunately, it is easy to prepare a ...

  • Factory settings

    This article main topic is about v2 factory settings and default use case, also discussing a few LAN attacks on high-level.

    When you get a cellular router from Advantech CZ, the default settings fall into one of the three cases:

    1. Router is pre-configured exactly to your needs.
    2. V2 router - with default v2 router generation configuration.
    3. V3 router - with default v3 generation configuration.

    As for the first possibility - router pre-configured exactly to your needs: as described in the first article, there are several ways how ...

    Securing routers - part II (security model)


    Written by Jan Otte on Monday 30 July 2018 in the category Default with the tags .

  • Be the first to comment
  • A very important topic to cover in this article series is something we call security model of the router.

    Before getting to that, let's look at the user model. There are a few user models being used in the operating systems based on Linux. Please note that this definition is something to make our security model more understandable and help with further understanding of the securing process, it is not a formal definition as used in information science.

  • Router pwned

    You are about to read the first article in the series of articles about securing our routers. The series is tailored to our router devices, teaching and showing some general and specific principles and also describing possibilities and use cases. While some of the knowledge here is usable also outside of the router devices, you should keep in mind that we are focusing on our cellular routers running Conel OS 6.x here.

    This first article is a basic building block. We are going to describe the device and its basic characteristics and possibilities of accessing the device with an accent on security. Also, some basic use cases are to be touched here and the terminology used for the rest of the series established.
