Title
Relative path traversal in the log export commands in AWS ParallelCluster CLI
Summary
The export-cluster-logs and export-image-logs commands in the AWS ParallelCluster CLI before version 3.16.0 contain a relative path traversal issue. An authenticated remote user with write access to the log export Amazon S3 bucket could use a crafted S3 object key to write files outside the intended export directory on the machine running the command. The written files would have names and content controlled by a third party, and would be created with the privileges of the user running the command. To remediate this issue, users should upgrade to version 3.16.0 or later.
