# Security digest: March 16, 2023

1 editorial brief.

## Take stock

- Check exposure: D-Link DIR-820L CVE-2023-25280: Unpatchable Router RCE . Anyone with a D-Link DIR-820L (DIR-820) router still in service, including small branch offices, home offices of remote staff and forgotten lab or guest networks.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.
