DescriptionGitHub Advisory

RustFS is a distributed object storage system built in Rust. From >= 1.0.0-alpha.1 to 1.0.0-alpha.79, invalid RPC signatures cause the server to log the shared HMAC secret (and expected signature), which exposes the secret to log readers and enables forged RPC calls. In crates/ecstore/src/rpc/http_auth.rs, the invalid signature branch logs sensitive data. This log line includes secret and expected_signature, both derived from the shared HMAC key. Any invalidly signed request triggers this path. The function is reachable from RPC and admin request handlers. This vulnerability is fixed in 1.0.0-alpha.80.

AnalysisAI

RustFS versions 1.0.0-alpha.1 through 1.0.0-alpha.79 expose the shared HMAC secret in server logs when processing invalidly signed RPC requests, allowing attackers with log access to obtain authentication credentials and forge RPC calls. The vulnerability stems from improper error handling in the HTTP authentication module that logs sensitive cryptographic material. …
