GHSA-C4RH-4376-GFF4 Improper certificate management in AWS IoT Device SDK v2

The AWS IoT Device SDK v2 for Java, Python, C++ and Node.js appends a user supplied Certificate Authority CA to the root CAs instead of overriding it on Unix systems. TLS handshakes will thus succeed if the peer can be verified either from the user-supplied CA or the system’s default trust-store...

GHSA-J3F7-7RMC-6WQJ Improper certificate management in AWS IoT Device SDK v2

The AWS IoT Device SDK v2 for Java, Python, C++ and Node.js appends a user supplied Certificate Authority CA to the root CAs instead of overriding it on macOS systems. Additionally, SNI validation is also not enabled when the CA has been "overridden". TLS handshakes will thus succeed if the peer...

Insecure Certificate Validation

aws/aws-iot-device-sdk-js-v2 is vulnerable to Insecure Certificate Validation. Attackers are able to compromise certificate authorities in their trust stores on Linux/Unix, by spoofing DNS records to bypass CA pinning...
