# Security digest: August 17, 2023

1 editorial brief.

## Take stock

- Check exposure: Junos J-Web CVE-2023-36845 Chain: Pre-Auth RCE on SRX/EX . Owners of Juniper SRX firewalls and EX switches on Junos builds older than the fixed releases with J-Web (HTTP/HTTPS web management) reachable from untrusted networks.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
