Executive brief
Azure Data Factory is Microsoft's cloud-based data integration service used to build ETL and data orchestration pipelines for enterprise data warehouses. An attacker can bypass cryptographic signature verification to gain unauthorized elevated privileges within the service over a network, potentially allowing them to manipulate data pipelines, access sensitive data, or compromise the integrity of data workflows without requiring prior authentication.
Technical details
The vulnerability exists in Azure Data Factory's cryptographic signature verification logic. An attacker on the network can craft messages with improper or forged signatures that fail verification, allowing them to escalate privileges and access functionality intended for authenticated or higher-privileged users. The flaw enables privilege escalation without requiring valid credentials or user interaction, making it directly exploitable from the network. The attack precondition is network reachability to the Azure Data Factory service endpoint. A patch or update is expected from Microsoft Security Response Center.
