Overview
rustfs is a high-performance distributed object storage software built using Rust, one of the most popular languages worldwide. Along with MinIO, it shares a range of advantages such as simplicity, S3 compatibility, open-source nature, support for data lakes, AI, and big data. Furthermore, it has a better and more user-friendly open-source license in comparison to other storage systems, being constructed under the Apache license.
Affected versions of this package are vulnerable to Insertion of Sensitive Information into Log File in the verify_rpc_signature function. An attacker can obtain sensitive authentication secrets by submitting requests with invalid signatures, causing the server to log the shared HMAC secret and expected signature, which can then be accessed by anyone with access to the logs. This information can be used to forge valid RPC signatures and perform unauthorized actions.
