Azure Sphere Unsigned Code Execution Vulnerability
FAQ: What version of Azure Sphere has the update that protects from this vulnerability?
All versions of Azure Sphere that are 21.02 and higher are protected from this vulnerability.
How do I ensure my Azure Sphere device has the update?
If your device is new or has not been connected to the internet for a while, connect the device to a secure, private local network with internet access and allow the device to automatically update itself. If the device is already online, verify that the operating system version 21.02 has been installed using the Azure Sphere CLI command:
azsphere device show-os-version
If the device is connected to the internet and does not yet have the latest update, check the update status with the following Azure Sphere

[HIGH] Vulnerability Spotlight: Multiple remote code execution vulnerabilities in Microsoft Azure Sphere
Claudio Bozzato and Lilith >_> of Cisco Talos discovered these vulnerabilities. Blog by Jon Munshaw.
Cisco Talos researchers recently discovered multiple vulnerabilities in Microsoft’s Azure Sphere, a cloud-connected and custom SoC platform designed specifically with IoT application security in mind. Internally, the SoC is made up of a set of several ARM cores that have different roles (e.g. running different types of applications, enforcing security, and managing encryption), and externally the Azure Sphere platform is supported by Microsoft’s Azure Sphere cloud, which handles secure updates, app deployment, and periodically verifying the device integrity to determine whether or not it should be allowed cloud access.
Talos discovered four vulnerabilities in Azure Sphere that could lead
