We can say with high confidence that many of these trends will not only continue, but gain new traction in the coming yea...

CVE-2021-40831

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...

CVE-2021-40830

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...

Additionally, SNI validation is also not enabled when the CA has been “overridden”. TLS handshakes will thus succeed if the peer...

PYSEC-2021-862

Connections initialized by the AWS IoT Device SDK v2 for Java versions prior to 1.4.2, Python versions prior to 1.6.1, C++ versions prior to 1.12.7 and Node.js versions prior to 1.5.3 did not verify server certificate hostname during TLS handshake when overriding Certificate Authorities CA in the...

CVE-2021-3672

A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS Domain Name Servers can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as we...

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS Domain Name Servers can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as we...

CVE-2021-3672

CVE-2021-3672 affects the c-ares library. A missing input validation check for host names returned by DNS can lead to domain hijacking, impacting confidentiality, integrity, and availability. Connected documents confirm this across multiple vendors/distributions (Astra Linux, AlmaLinux, Red Hat a...

Improper Certificate Validation

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...

CVE-2021-40831 Missing SNI validation and inconsistent CA override function behavior within AWS IoT Device SDKs on Apple devices

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...

CVE-2021-40830

CVE-2021-40830 affects the AWS IoT Device SDK v2 for Java, Python, C++, and Node.js on Linux/Unix. The root cause is that the SDK appends a user-supplied CA to the system trust store instead of overriding it, which can allow TLS handshakes to succeed using either the user-supplied CA or the defau...
