# Publicly accessible Azure VM with high/critical vulnerabilities has an assigned managed identity that can read data from crown jewel storage

## Description{% #description %}

A publicly accessible Azure VM has one or more open high or critical severity vulnerabilities and an assigned managed identity that can read data from a crown jewel blob container. If the VM is compromised, an attacker could use the managed identity to read or exfiltrate business-critical data.

## Remediation{% #remediation %}

1. Apply security updates to remediate the vulnerability and restrict public network access to the virtual machine. See [Guest updates and host maintenance](https://learn.microsoft.com/en-us/azure/virtual-machines/updates-maintenance-overview) and [Azure network security groups](https://learn.microsoft.com/en-us/azure/virtual-network/network-security-groups-overview).
1. Remove unnecessary Blob data read permissions from the managed identity. See [Remove Azure role assignments](https://learn.microsoft.com/en-us/azure/role-based-access-control/role-assignments-remove).
