Microsoft warns again (for the second time) its customers for the BlueKeep vulnerability or CVE-2019-0708. Let us recall that the specific security gap exists in older versions of Windows and to the Remote Desktop Protocol (RDP) service.
The company published the second warning because the last two days appeared online, exploits with two different PoCs (for example)
"Microsoft is convinced that there is an exploit on this issue, and if recent reports are accurate, almost a million online PCs are still vulnerable to CVE-2019-0708"Said Simon Pope, Director of Incident Response, at the Microsoft Security Response Center (MSRC).
Scans for computers that are vulnerable to BlueKeep continue for a week and are reported to have an ever-increasing rate of vulnerable systems. Microsoft, after the emergence of public PoC warns again before the attacks begin.
Updates that fix the issue are available to all the older Microsoft operating systems (Windows XP, Windows Vista, Windows 7, Windows Server 2003, and Windows Server 2008) for all versions of Windows that are vulnerable to BlueKeep attacks.
The company had warned for the first time in 14 May when it released the updates that fixed the issue. Then the company had said that the flaw was dangerous because it not only allowed remote execution but also because it was a worm (it has the ability to replicate).
“Our recommendation remains the same. We recommend that you update all affected systems as soon as possible, ”says Simon Pope.
Here is to say that the PoC we give above through GitHub is not as dangerous as it can hit a remote vulnerable system, but it can not run code on it.
However experienced reverse engineers were able to execute remote code execution but did not publish any PoCs for fear of a mass infection.
The security researchers who managed to create a working exploit are among the Companies Zerodium, McAfee, Kaspersky, Check Pointst, MalwareTechAnd Valthek.
