Microsoft Patches Azurescape Bug From Azure Platform

Share post:

Microsoft has fixed a vulnerability in Azure Container Instances, a cloud-based service that allows companies to install packaged applications called containers in the cloud, called Azurescape.

The vulnerability allowed malicious containers to take over containers from other customers on their platforms.

Microsoft has since informed customers who may be affected by the vulnerability to switch their privileged credentials for containers provided on the platform before August 31.

According to Palo Alto Networks researchers who reported Azurescape to Microsoft, the vulnerability “allowed malicious users to compromise the multitenant Kubernetes clusters hosting ACI.”

The researchers also pointed out that the problem started with code used by ACI that was published nearly five years ago and was vulnerable to escaping bugs in the container, so it was sufficient to exploit the vulnerability to break out of the container and execute code with elevated privileges on the underlying machine.
