Spectre and Meltdown Vulnerabilities - (CVE-2017-5715, CVE-2017-5753, and CVE-2017-5754)
Digi is aware of the Spectre and Meltdown vulnerabilities that were recently released. These vulnerabilities impact the confidentiality of data running on Intel, AMD and ARM processors.
For Digi hardware products, we do not use Intel or AMD processors, and as a consequence the "Meltdown" vulnerability does not affect Digi hardware products.
For the Spectre vulnerability, Digi security teams are working to determine the practical impacts and patches on Digi hardware products that use ARM processors.
For Digi Remote Manager & Device Cloud, we are working with our providers to address Spectre and Meltdown.
Additional information will be provided as soon as it is available. For more information on these vulnerabilities, please see the website https://meltdownattack.com/

Evaluation of Security Vulnerability VU#561444
Expanded info on CVE-2014-9222, CVE-2014-9223
Many Digi products contain and use the RomPager by Allegrosoft web server technology. It has come to our attention that this embedded web server, which is used for management of our devices contains what we have defined as a critical vulnerability. We urge any customer who may have one of these products where the administrative webserver is available on non-secure networks to either upgrade the firmware to a patched version or to disable the web server for management of these devices.
With global scalability, certifications, and compliance, Digi has developed Digi TrustFence™, a security framework along with a series of best practices making our approach to security stand apart in the marketplace, including:
A dedicated security office ensuring that security best practices are incorporated into the engineering design process. Our approach incorporates accepted guidelines and processes that take into consideration product design and testing such as those defined by the American Society for Quality/ Failure Mode Effects Analysis; iSixSigma/DFMEA; ISO9001 SDLC, Penetration Testing Execution Standard and OWASP; as well as emerging standards such as the Online Trust Alliance (OTA). Additionally, we are active participants in established standards bodies including the ZigBee® Alliance, Thread Group, and the SunSpec Alliance, and are members of established organizations such as the Center for Internet Security.
Our standalone security lab tests our products in a variety of ways, including vulnerability analysis and penetration testing. Our skilled testing staff has received certification from leading security bodies including (ISC)2, EC-Council – Licensed Pen Tester (LPT/ECSA/CEH), and in Six Sigma capabilities. In addition, we go beyond general information technology certifications to offer industry expertise in certifications that apply to specific markets, such as energy, government, medical, industrial, retail, transportation and more.
Our dedicated security team regularly collaborates with product and engineering teams on key security issues. In the design process we take a systematic security approach – encompassing design, software, physical attributes and more – making security part of the product lifecycle. We also involve our customers and partners in the process to ensure a real-life approach that tests security within actual deployment environments.
By providing ongoing threat measurement and monitoring services as well as performing internal and external security audits on a regular basis, we ensure our cloud platform offers up-to-date security patches, and provide ongoing proactive communication regarding upcoming threats. Our cloud platforms conform to the latest security frameworks and have acquired a PCI Report on Compliance as a managed service provider.
