Virtual Machine Extensions Installed
More Info:
Azure virtual machine extensions are small applications that provide post-deployment configuration and automation tasks on Azure virtual machines. These extensions run with administrative privileges and could potentially access anything on a virtual machine. The Azure Portal and community provide several such extensions.

Remediation
Here are the step-by-step instructions to remediate the “Virtual Machine Extensions Installed” misconfiguration in Azure using the Azure console:
- Log in to the Azure portal (https://portal.azure.com/).
- Navigate to the virtual machine that has the misconfiguration.
- Click on the virtual machine to open its overview page.
- In the left-hand menu, click on “Extensions.”
- In the list of extensions, locate the extension that needs to be removed and click on it.
- Click on the “Uninstall” button to remove the extension from the virtual machine.
- Confirm the removal by clicking “Yes” on the confirmation page.
- Wait for the extension to be uninstalled from the virtual machine.
Once the extension has been successfully uninstalled, the misconfiguration will be remediated. It is important to note that some extensions may be required for the proper functioning of the virtual machine, so it is recommended to consult with the appropriate stakeholders before removing any extensions.
To remediate the misconfiguration “Virtual Machine Extensions Installed” in Azure using Azure CLI, follow the below steps:
Step 1: Open the Azure CLI in your system.
Step 2: Run the following command to list all the virtual machines in the Azure subscription:
az vm list --query "[].{name:name, location:location, resourceGroup:resourceGroup}"
Step 3: From the list of virtual machines, select the virtual machine for which you want to remove the extensions.
Step 4: Run the following command to check the list of extensions installed on the virtual machine:
az vm extension list --resource-group <resource-group-name> --vm-name <virtual-machine-name> --query "[].{name:name, publisher:publisher, type:type, autoUpgradeMinorVersion:autoUpgradeMinorVersion, settings:settings, protectedSettings:protectedSettings, provisioningState:provisioningState, instanceView:instanceView}"
Step 5: From the list of extensions, select the extension that you want to remove.
Step 6: Run the following command to remove the selected extension from the virtual machine:
az vm extension delete --resource-group <resource-group-name> --vm-name <virtual-machine-name> --name <extension-name>
Step 7: After running the above command, the extension will be removed from the virtual machine.
Step 8: Repeat steps 4 to 7 for all the extensions that you want to remove from the virtual machine.
Step 9: Once all the extensions are removed, the misconfiguration “Virtual Machine Extensions Installed” will be remediated in Azure.
To remediate the issue of virtual machine extensions installed in Azure using Python, you can follow the below steps:
Step 1: Connect to Azure Subscription You need to connect to your Azure subscription using Python SDK. You can use the below code to authenticate and connect to the subscription.
from azure.identity import AzureCliCredential
from azure.mgmt.compute import ComputeManagementClient
from azure.mgmt.resource import ResourceManagementClient
credential = AzureCliCredential()
subscription_id = 'your_subscription_id'
compute_client = ComputeManagementClient(credential, subscription_id)
resource_client = ResourceManagementClient(credential, subscription_id)
Step 2: Get Virtual Machines You need to fetch the list of all virtual machines in your subscription. You can use the below code to get the list of virtual machines.
vms = compute_client.virtual_machines.list_all()
Step 3: Get Virtual Machine Extensions You need to get the list of all virtual machine extensions installed on each virtual machine. You can use the below code to get the list of extensions.
for vm in vms:
extensions = compute_client.virtual_machine_extensions.list(resource_group_name=vm.id.split('/')[4], virtual_machine_name=vm.name)
for extension in extensions:
print(extension.name)
Step 4: Remove Virtual Machine Extensions You need to remove the virtual machine extensions from each virtual machine. You can use the below code to remove the extensions.
for vm in vms:
extensions = compute_client.virtual_machine_extensions.list(resource_group_name=vm.id.split('/')[4], virtual_machine_name=vm.name)
for extension in extensions:
compute_client.virtual_machine_extensions.delete(resource_group_name=vm.id.split('/')[4], virtual_machine_name=vm.name, extension_name=extension.name)
Note: Please be cautious while deleting the extensions as it may impact the functionality of your virtual machines.
By following the above steps, you can remediate the issue of virtual machine extensions installed in Azure using Python.
