# Security digest: August 29, 2023

1 editorial brief.

## Take stock

- Check exposure: ZeroQlik . Owners of self-managed Qlik Sense Enterprise for Windows servers that were reachable from the internet, especially any not updated past the September 2023 CVE-2023-48365 patches.
- 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

- **Check exposure** [Qlik Sense ZeroQlik Bugs: Pre-Auth RCE Used by Cactus](https://erroneo.us/security/briefs/qlik-sense-cve-2023-41265-41266-zeroqlik-cactus/index.md): Patched since 2023, but the first fix was incomplete and Cactus ransomware hit hundreds of exposed servers; confirm every Qlik Sense server is past the CVE-2023-48365 fix, off the open internet, and free of qle.ttf.

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
