In-Spectre-Meltdown is a PoC developed by Viral Maniar using Python and Powershell to check speculative execution side-channel attacks that affect many modern processors and operating systems designs that allows unprivileged processes to steal secrets from privileged processes.
In the last hours, the vulnerabilities of the CPU have had a great prominence even in the non-specialized press. So, I think that would be useful trying to summarize the situation in a simple way.
In this great speech on BlackHat Europe 2017, Mark Ermolov and Maxim Goryachy by Positive Technology talks about the Intel Management Engine subsystem and how the recently discovered vulnerabilities can be used in order to compromise a system.
UPDATE – Apple released the security patch for the bug: https://support.apple.com/en-us/HT208315 The security fate discovered in MacOS High Sierra by Lemi Orhan Ergin is so serious that it is hard to believe it’s real: you can become root without typing a password.
Two vulnerabilities and an exploit POC impacting the Exim MTA have been publicly disclosed, identified as CVE-2017-16943 & CVE-2017-16944 The vulnerabilities could allow remote attackers to execute arbitrary code or cause a denial of service via vectors involving BDAT commands.
