Frequently asked questions (Microsoft)
What is RTOS?
Azure RTOS is an embedded development suite including a small but powerful operating system that provides reliable, ultra-fast performance for resource-constrained devices. See Azure RTOS Overview for more information.
What is Azure RTOS GUIX Studio?
Azure GUIX embedded GUI is Microsoft’s advanced, industrial grade GUI solution designed specifically for deeply embedded, real-time, and IoT applications. Microsoft also provides a full-featured WYSIWYG desktop design tool named Azure RTOS GUIX Studio, which allows developers to design their GUI on the desktop and generate Azure RTOS GUIX embedded GUI code that can then be exported to the target. See Azure RTOS GUIX and Azure RTOS GUIX Studio for more information.
According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?
The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally.
For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.
According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?
An attacker must send the user a malicious input file and convince the user to open said input file.
