Short explanation
In MongoDB Rust Driver 3.9.1, a component recording diagnostic tracing data can capture command content before automatic client-side field level encryption is applied [S0]. In deployments enabling optional tracing alongside automatic encryption, parties with read access to exported trace data can obtain designated field values [S0].
This vulnerability allows sensitive data designated for encryption to leak into diagnostic traces, enabling unauthorized parties to read secret field values without accessing encryption keys [S0].
What should be done?
- Follow vendor advisories to review appropriate updates [S0]
- Evaluate the optional tracing configuration in deployments [S0]
Chain of evidence and sources
MongoDB Rust Driver, otomatik istemci tarafı şifreleme uygulanmadan önce komut içeriğini yakalayabilir [S0].
İzleme verilerine erişimi olan taraflar, şifreleme anahtarlarına ihtiyaç duymadan şifrelenmesi gereken alan değerlerini elde edebilir [S0].
Show the technical text from the sources
A component of the MongoDB Rust Driver that records diagnostic tracing data can capture command content before automatic client-side field level encryption is applied. In deployments that turn on the optional tracing capability together with automatic in-use encryption, a party with read access to the application's exported trace data may obtain field values that the application designated for encryption, without access to the encryption keys. This may result in unintended disclosure of data.
