Cybersecurity researchers from Palo Alto Networks Unit 42 disclosed details of a new security flaw affecting Microsoft's Service Fabric that could be exploited to obtain elevated permissions and seize control of all nodes in a cluster. Azure Service Fabric is Microsoft's platform-as-a-service and a container orchestrator solution used to build and deploy microservices-based cloud applications across a cluster of machines.

Microsoft has fixed a container escape bug dubbed FabricScape in the Service Fabric application hosting platform that let threat actors escalate privileges to root, gain control of the host node, and compromise the entire SF Linux cluster. Additional details on how CVE-2022-30137 can be exploited to execute code and take over SF Linux clusters are available in Unit 42's report.
