services / Azure / Virtual Machines

An Azure virtual machine: a production compute resource running an OS, applications, attached disks, network interfaces, and optionally a managed identity.

A VM typically supports a single organizational function; control-plane and data-plane access to it can expose on-disk data, attached managed-identity credentials, and the hosted service's availability.

Creating or updating a VM's model can attach a managed identity or admin credentials, change the OS disk/image, or alter extensions, letting an attacker grant themselves the identity's privileges or plant a backdoored configuration.

Risks

1. Privilege escalation (CRITICAL)
2. Data manipulation (HIGH)

Scope: HIGH

This privilege may grant access to sensitive data from a single organizational function, or allow interruption of a service supporting a single organizational function.
