Headline
CVE-2023-30610: AWS SDK for Rust will log AWS credentials when TRACE-level logging is enabled for request sending
aws-sigv4 is a rust library for low level request signing in the aws cloud platform. The aws_sigv4::SigningParams struct had a derived Debug implementation. When debug-formatted, it would include a user’s AWS access key, AWS secret key, and security token in plaintext. When TRACE-level logging is enabled for an SDK, SigningParams is printed, thereby revealing those credentials to anyone with access to logs. All users of the AWS SDK for Rust who enabled TRACE-level logging, either globally (e.g. RUST_LOG=trace), or for the aws-sigv4 crate specifically are affected. This issue has been addressed in a set of new releases. Users are advised to upgrade. Users unable to upgrade should disable TRACE-level logging for AWS Rust SDK crates.

The `aws_sigv4::SigningParams` struct had a derived `Debug` implementation. When debug-formatted, it would include a user's AWS access key, AWS secret key, and security token in plaintext. When TRACE-level logging is enabled for an SDK, `SigningParams` is printed, thereby revealing those credentials to anyone with access to logs. ### Impact All users of the AWS SDK for Rust who enabled TRACE-level logging, either globally (e.g. `RUST_LOG=trace`), or for the `aws-sigv4` crate specifically. ### Patches - Versions >= `0.55.1` - `0.54.2` - `0.53.2` - `0.52.1` - `0.51.1` - `0.50.1` - `0.49.1` - `0.48.1` - `0.47.1` - `0.46.1` - `0.15.1` - `0.14.1` - `0.13.1` - `0.12.1` - `0.11.1` - `0.10.2` - `0.9.1` - `0.8.1` - `0.7.1` - `0.6.1` - `0.5.3` - `0.3.1` - `0.2.1` ### Workarounds Disable TRACE-level logging for AWS Rust SDK crates.
