Severity It appears these are a collection of many different and serious vulnerabilities. BlueKeep was one vulnerability in near legacy versions of Windows; these are different vulnerabilities in modern Windows. Mitigations - Enable NLA and leave it enabled for all external and internal systems. This raises exploitation requirements to needing credentials for some of the issues - Some of these vulnerabilities are not exploitable on Windows 7 and 2008 if you haven’t enabled RDP 8+, aka RemoteFX (rich experiences) and the like. These are available by default in later versions of Windows. Wormable? Microsoft say yes: https://msrc-blog.microsoft.com/2019/08/13/patch-new-wormable-vulnerabilities-in-remote-desktop-services-cve-2019-1181-1182/ DejaBlue Funny name by @Michael Norris .

CVE-2018-13379 is being exploited in the wild on Fortigate SSL VPN firewalls. These exist as a perimeter security control, so it's a bad vulnerability.

Came across this on my travels: https://portswigger.net/daily-swig/webmin-backdoor-blamed-on-software-supply-chain-breach Webmin software was backdoored for over a year. If you're using one of those vulnerable versions, update now! According to shodan and some google dorks, there are quite a lot still vulnerable

No details on this yet, expect them on Tuesday. Should be pretty funny.
