Description

On Scalable Platforms, an administrator with permissions to edit and install the Access Control Policy and NAT rules can create a NAT rule that redirects traffic to the Gateway's Sync interface, bypassing the built-in Sync protection. This could allow the administrator to execute operating system commands and write files on the Gateway with superuser privileges.
