    Improper Verification of Cryptographic Signature

    aws-cdk-lib is a Version 2 of the AWS Cloud Development Kit library

    Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to the tls.connect method setting rejectUnauthorized to false by default. An attacker can intercept and manipulate the data transmitted over the connection by exploiting the lack of proper TLS verification.ֿ

    Note

    1. The issuer URL is specified by CDK users when defining their CDK application. If they choose to connect to an unauthorized OIDC provider, CDK should not prevent this. Furthermore, the code block is executed within a Lambda environment, which helps mitigate the risk of MITM attacks.

    2. After upgrading to the fixed version, ensure the feature flag @aws-cdk/aws-iam:oidcRejectUnauthorizedConnections is set to true in cdk.context.json or cdk.json. More details on AWS CDK feature flags setting can be found here.

    How to fix Improper Verification of Cryptographic Signature?

    Upgrade aws-cdk-lib to version 2.177.0 or higher.
