CVE-2025-69255: RustFS gRPC GetMetrics deserialization panic enables remote DoS

RustFS is a distributed object storage system built in Rust. In versions 1.0.0-alpha.13 to 1.0.0-alpha.77, a malformed gRPC GetMetrics request causes get_metrics to unwrap() failed deserialization of metric_type/opts, panicking the handler thread and enabling remote denial of service of the metrics endpoint. This issue has been patched in version 1.0.0-alpha.78.

Root Cause Analysis

The vulnerability described is a remote denial of service in the GetMetrics gRPC endpoint of RustFS. The advisory explicitly points to rustfs/src/storage/tonic_service.rs:1775-1782 and the use of .unwrap() on deserialization operations. The provided patch eb33e82b56ed11fd12bb39416359d8d60737dc7a confirms this. The changes in rustfs/src/storage/tonic_service.rs clearly show the replacement of .unwrap() with proper error handling within the get_metrics function of the NodeService struct. When a malformed request is sent, the Deserialize::deserialize function returns an Err, and the subsequent .unwrap() call triggers a panic, crashing the worker thread. The vulnerable function is therefore NodeService::get_metrics.
