Any other systems/applications in which hijacked user previously logged in (May include another Remote Desktop sessions, Network Share mappings, applications which require another credentials, E-mail etc.) Tested on: Windows 2012 R2 Windows 2008 Windows 10 Windows 7 Proof of Concept: http://www.korznikov.com/2017/03/0-day-or-feature-privilege-escalation.html @nopernik _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
