Exploitation status
- CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
- US federal civilian agencies are required to remediate it by 2022-05-04. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.
Required action
The impacted product is end-of-life and should be disconnected if still in use.
