# Security digest: March 1, 2019

1 editorial brief.

## Take stock

- Check exposure: Sitecore CVE-2019-9874/9875: Anti-CSRF Deserialization RCE . Owners of Sitecore CMS 6.6.3 through XP 8.2.7 without SC Hotfix 313001-1, and of Sitecore XP 9.0 through 9.1 Initial Release without the 313001-2 hotfix or an upgrade, especially with /sitecore/shell reachable from the internet.
- 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** [Sitecore CVE-2019-9874/9875: Anti-CSRF Deserialization RCE](https://erroneo.us/security/briefs/sitecore-anticsrf-cve-2019-9874-9875-deserialization-rce/index.md): These are six-year-old bugs with hotfixes since 2019 and 2020; the risk sits with forgotten Sitecore 6.6 to 8.2 sites and early 9.x installs that never got the anti-CSRF hotfix, which an unauthenticated POST can take over.

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
