Technical details

Multiple vulnerabilities exist in the REST API interface of HPE Networking SD-WAN Orchestrator that permit unauthenticated remote attackers to circumvent web authentication mechanisms. The vulnerabilities enable attackers on the network to directly invoke protected system functions and access sensitive information through API endpoints. The attack requires network reachability to the REST API interface but no prior authentication or user interaction. Successful exploitation allows viewing and modifying potentially sensitive configuration data on the target system. A patch is expected to be available via HPE support.
