Unauthenticated gRPC access via wildcard address binding
Published Jul 18, 2024 · Updated Aug 7, 2024
Improper interface exposure in PyTorch TorchServe 0.3.0 through 0.10.0 allows remote attackers to reach its gRPC services. ModelServer creates both Netty gRPC servers by port alone, causing inference port 7070 and management port 7071 to bind to wildcard addresses instead of localhost. Default standalone deployments expose inference and model-management operations without prior access; SageMaker and EKS PyTorch inference containers are unaffected.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=>= 0.3.0, < 0.11.0
- Affected versionversion=0.3.0 <0.11.0
