Mbed TLS before 2.28.10 and 3.x before 3.6.3, on the client side, accepts servers that have trusted certificates for arbitrary hostnames unless the TLS client application calls mbedtls_ssl_set_hostname.

Weakness

The product initializes or sets a resource with a default that is intended to be changed by the administrator, but the default is not secure.

Affected Software

Name Vendor Start Version End Version
Mbedtls Ubuntu focal *

Extended Description

Developers often choose default values that leave the product as open and easy to use as possible out-of-the-box, under the assumption that the administrator can (or should) change the default value. However, this ease-of-use comes at a cost when the default is insecure and the administrator does not change it.
