Microsoft has fixed a vulnerability in Azure Container Instances called Azurescape that allowed a malicious container to take over containers belonging to other customers on the platform.
An adversary exploiting Azurescape could execute commands in the other users’ containers and gain access to all their data deployed to the platform, the researchers say.
Microsoft has notified customers that were potentially impacted by Azurescape to change privileged credentials for containers deployed to the platform before August 31.
Microsoft’s Azure Container Instances is a cloud-based service that allows companies to deploy packaged applications on the cloud.
When containers are deployed, ACI will isolate them from other running containers to prevent them from sharing memory space and interacting with each other.
Issue az container exec to run a command on the uploaded container.
