BlueKeep second warning from Micrsoft after PoC

Microsoft warns again (for a second time) to its customers for BlueKeep or CVE-2019-0708 vulnerability. Note that this security gap exists in earlier versions of Windows and Remote Desktop Protocol (RDP).

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, Incident Response Manager 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 encourage you to update as soon as possible all affected systems, "said 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 achieve remote code execution but did not publish a PoC in the face of a massive infection.

Security researchers who have managed to create a functional exploit are from companies Zerodium, McAfee, Kaspersky, Check Pointst, MalwareTechAnd Valthek.
