When running the AWS Serverless Application Model Command Line Interface (SAM CLI) build process with Docker and symlinks are included in the build files, the container environment allows a user to access privileged files on the host by leveraging the elevated permissions granted to the tool. A user could leverage the elevated permissions to access restricted files via symlinks and copy them to a more permissive location on the container. Users should upgrade to v1.133.0 or newer and ensure any forked or derivative code is patched to incorporate the new fixes.

The version of AWS SAM CLI installed on the remote host is prior to 1.133.0 and is, therefore, affected by multiple vulnerabilities:

  - When running the AWS SAM CLI build process with Docker and symlinks are included in the build files, the container     environment allows a user to access privileged files on the host by leveraging the elevated permissions granted to     the tool. A user could leverage the elevated permissions to access restricted files via symlinks and copy them to a     more permissive location on the container. This issue affects AWS SAM CLI <= v1.132.0 and has been resolved in v1.133.0.
    To retain the previous behavior after upgrading and allow symlinks to resolve on the host machine, please use the     explicit '--mount-symlinks' parameter. (CVE-2025-3047)

  - After completing a build with AWS SAM CLI which include symlinks, the content of those symlinks are copied to the     cache of the local workspace as regular files or directories. As a result, a user who does not have access to those     symlinks outside of the Docker container would now have access via the local workspace. This issue affects AWS SAM CLI     <= v1.133.0 and has been resolved in v1.134.0. After upgrading, users must re-build their applications using the sam     build --use-container to update the symlinks. (CVE-2025-3048)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - When running the AWS Serverless Application Model Command Line Interface (SAM CLI) build process with
    Docker and symlinks are included in the build files, the container environment allows a user to access
    privileged files on the host by leveraging the elevated permissions granted to the tool. A user could
    leverage the elevated permissions to access restricted files via symlinks and copy them to a more
    permissive location on the container. Users should upgrade to v1.133.0 or newer and ensure any forked or
    derivative code is patched to incorporate the new fixes. (CVE-2025-3047)
