# IBM Guardium Data Protection: hard-coded crypto key leaks sensitive information remotely

IBM Guardium Data Protection 12.1 and 12.2 ship with a hard-coded cryptographic key. A remote attacker can use that key to obtain sensitive information.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Guardium Data Protection version against 12.1 and 12.2 in the appliance or console.
- unknown for any other check; the sources do not say which configuration or file exposes the key.

## Fix

- Move to a fixed IBM Guardium Data Protection release; the sources do not name the version.
- unknown for any other action; check the IBM security bulletin for the fixed build.
