App Control: Local State of Banned Remains After Removing Global Ban

Products

• Carbon Black App Control (formerly Cb Protection)

Issue/Introduction

• File was marked as Globally Banned
• Global Ban was then removed from the file
• File has a Local State of Banned

Environment

• App Control Server: All Supported Versions
• App Control Agent: All Supported Versions

Cause

The local state is only checked upon execution of the file, so removing the Global Ban from the console does not immediately remove the local state of banned

Resolution

• After removing the global ban the locally banned file will become unbanned on execution
• At time of execution, the agent will see the global ban has been removed, reverse the local state of banned, and will allow the file to execute
