Man-in-the-Middle (MitM)

mongodb-client-encryption is a The Node.js wrapper for libmongocrypt

Affected versions of this package are vulnerable to Man-in-the-Middle (MitM). A specific version of the Node.js mongodb-client-encryption module does not perform correct validation of the KMS server’s certificate. This vulnerability in combination with a privileged network position active MITM attack could result in interception of traffic between the Node.js driver and the KMS service rendering client-side field level encryption (CSFLE) ineffective.

This issue affects mongodb-client-encryption module version 1.2.0, which was available from 2021-Jan-29 and deprecated in the NPM Registry on 2021-Feb-04. This vulnerability does not impact driver traffic payloads with CSFLE-supported key services from applications residing inside the AWS, GCP, and Azure nework fabrics due to compensating controls in these environments. This issue does not impact driver workloads that don’t use Field Level Encryption.

How to fix Man-in-the-Middle (MitM)?

Upgrade mongodb-client-encryption to version 1.2.1 or higher.
