- Public proof of concept: none known.
Our recommendation
- Check whether any client operates HPE Private 5G Core and at which version.
- If affected, read HPE bulletin HPESBNW05179 for the fixed version and plan the upgrade as high priority.
- Confirm that the core's interfaces are not reachable from the internet.
- Monitor for unexpected service outages and re-check NVD and CISA KEV once analysis is complete.
