services / Azure / Load Balancer

Azure Load Balancer distributes inbound/outbound traffic across a pool of backend instances (VMs) using load-balancing and NAT rules.

Sits in the path of live production traffic for the backend pool it serves; write access lets an attacker redirect that traffic to attacker-controlled backends. Rated HIGH rather than CRITICAL because impact is scoped to the traffic routed through this specific load balancer rather than whole-network segmentation.

Microsoft.​Network/​loadBalancers/​delete

Deletes the load balancer, removing the traffic-distribution front end and causing outage for every backend it serves.

Risks
