# Security digest: October 27, 2024

1 editorial brief.

## Take stock

- Check exposure: Cleo MFT CVE-2024-50623 and CVE-2024-55956: Cl0p RCE . Anyone running Cleo Harmony, VLTrader or LexiCom below 5.8.0.24, and anyone whose Cleo server was internet-reachable between October and December 2024 without a completed compromise assessment.
- 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** [Cleo MFT CVE-2024-50623 and CVE-2024-55956: Cl0p RCE](https://erroneo.us/security/briefs/cleo-harmony-vltrader-lexicom-cve-2024-50623-55956-rce/index.md): The fix has existed since December 2024; the job now is proving every Cleo server runs 5.8.0.24 or later and that no host exposed during the Cl0p campaign still carries its backdoor.

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
