BlueKeep RCE Vulnerability in Remote Desktop Protocol Let Hackers Hijack Target Computers Without Login Credentials

Bluekeep a wormable critical RCE vulnerability in Remote desktop services let hackers access the vulnerable machine without authentication. As vulnerability is wormable, it could rapidly compromise millions of machine in a short period.

Successful exploitation of the vulnerability allows a remote attacker to run arbitrary code on the target system, and the attacker can install programs to track user changes, delete data and to create a user account with elevated privileges.

The vulnerability can be tracked as CVE-2019-0708 and it affects multiple windows operating systems that includes both the supported and non-supported versions.

Microsoft released a patch for BlueKeep vulnerability on May 14 that addresses how Remote Desktop Services handles connection requests.

Following are the affected versions

  • Windows 2003
  • Windows XP
  • Windows Vista
  • Windows 7
  • Windows Server 2008
  • Windows Server 2008 R2

Systems that are running Windows 8 and 10 are not affected by this vulnerability. Microsoft patched the vulnerability for the supported versions as well an extra step to patch non-supported versions.

0patch released Micropatch for BlueKeep, that will be useful for computers in which the Microsoft’s update was not applied and in some mission-critical systems such as ATM’s or ICS where the restart is not possible.

At this moment the micro patch released by 0patch is only is for 32-bit Windows XP SP3 only, but 0patch said it would be ported to Server 2003.

McAfee security researchers created a Proof-of-Concept (PoC) that would use the CVE-2019-0708 vulnerability that could remotely execute the code on the victim’s machine to launch the calculator application.

Attackers could exploit the vulnerability in the wild in the near future, and it may cause a panic situation as like the WannaCry. System administrators are urged to apply the patch as soon as possible.

Mitigations

  • Block Remote Desktop Services if they are not in use.
  • Block TCP port 3389 at the enterprise perimeter firewall.
  • Apply the patch to the vulnerable Machines that have RDP Enabled.
