Name of the Vulnerable Software and Affected Versions AWS SDK for .NET versions 4.0.0 through 4.0.3.2

Description The AWS SDK for .NET, used with Amazon Web Services for building scalable solutions, is affected by an issue where applications could be configured to improperly route AWS API calls to non-existent or non-AWS hosts. This occurs when specific values are used for the region input field when calling AWS services. An attacker with access to the environment where the SDK is used could set the region input field to an invalid value.
