Technical Description
The AWS SDK for Java enables Java developers to work with Amazon Web Services. A partial-path traversal issue exists within the `downloadDirectory` method in the AWS S3 TransferManager component of the AWS SDK for Java v1 prior to version 1.12.261. Applications using the SDK control the `destinationDirectory` argument, but S3 object keys are determined by the application that uploaded the objects. The `downloadDirectory` method allows the caller to pass a filesystem object in the object key but contained an issue in the validation logic for the key name. A knowledgeable actor could bypass the validation logic by including a UNIX double-dot in the bucket key. Under certain conditions, this could permit them to retrieve a directory from their S3 bucket that is one level up in the filesystem from their working directory. This issue’s scope is limited to directories whose name prefix matches the destinationDirectory. E.g. for destination directory`/tmp/foo`, the actor can cause a download
