description The RDP termdd.sys driver improperly handles binds to internal-only channel MS_T120, allowing a malformed Disconnect Provider Indication message to cause use-after-free. With a controllable data/size remote nonpaged pool spray, an indirect call gadget of the freed channel is used to achieve arbitrary code execution. Windows 7 SP1 and Windows Server 2008 R2 are the only currently supported targets. Windows 7 SP1 should be exploitable in its default configuration, assuming your target selection is correctly matched to the system's memory layout. HKLM\SYSTEM\CurrentControlSet\Control\TerminalServer\Winstations\RDP-Tcp\fDisableCam *needs* to be set to 0 for exploitation to succeed against Windows Server 2008 R2. This is a non-standard configuration for normal servers, and the target will crash if the aforementioned Registry key is not set! If the target is crashing regardless, you will likely need to determine the non-paged pool base in kernel memory and set it as the GROOMBASE option. id MSF:EXPLOIT/WINDOWS/RDP/CVE_2019_0708_BLUEKEEP_RCE last seen 2020-06-14 modified 2020-04-21 published 2019-08-22 references reporter Rapid7 source https://github.com/rapid7/metasploit-framework/blob/master//modules/exploits/windows/rdp/cve_2019_0708_bluekeep_rce.rb title CVE-2019-0708 BlueKeep RDP Remote Windows Kernel Use After Free description This module checks a range of hosts for the CVE-2019-0708 vulnerability by binding the MS_T120 channel outside of its normal slot and sending non-DoS packets which respond differently on patched and vulnerable hosts.

NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS19_MAY_4499164.NASL description The remote Windows host is missing security update 4499175 or cumulative update 4499164. It is, therefore, affected by multiple vulnerabilities : - A new subclass of speculative execution side channel vulnerabilities, known as Microarchitectural Data Sampling, exist in Windows. An attacker who successfully exploited these vulnerabilities may be able to read privileged data across trust boundaries. In shared resource environments (such as exists in some cloud services configurations), these vulnerabilities could allow one virtual machine to improperly access information from another. In non-browsing scenarios on standalone systems, an attacker would need prior access to the system or an ability to run a specially crafted application on the target system to leverage these vulnerabilities. (CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2019-11091) - A denial of service vulnerability exists when .NET Framework and .NET Core improperly process RegEx strings. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application.

The update addresses the vulnerability by correcting how .NET Framework and .NET Core applications handle RegEx string processing. (CVE-2019-0820) - A remote code execution vulnerability exists when Microsoft Windows OLE fails to properly validate user input. An attacker could exploit the vulnerability to execute malicious code. (CVE-2019-0885) - An elevation of privilege vulnerability exists when the Windows Kernel improperly handles key enumeration. An attacker who successfully exploited the vulnerability could gain elevated privileges on a targeted system. A locally authenticated attacker could exploit this vulnerability by running a specially crafted application. The security update addresses the vulnerability by helping to ensure that the Windows Kernel properly handles key enumeration. (CVE-2019-0881) - An elevation of privilege vulnerability exists in Microsoft Windows when Windows fails to properly handle certain symbolic links. An attacker who successfully exploited this vulnerability could potentially set certain items to run at a higher level and thereby elevate permissions. (CVE-2019-0936) - An spoofing vulnerability exists when Internet Explorer improperly handles URLs. An attacker who successfully exploited this vulnerability could trick a user by redirecting the user to a specially crafted website. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. (CVE-2019-0921) - A remote code execution vulnerability exists in the way that Microsoft browsers access objects in memory. The vulnerability could corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2019-0940) - A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers.

An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET Framework (or .NET core) application. The update addresses the vulnerability by correcting how .NET Framework and .NET Core applications handle RegEx string processing. (CVE-2019-0820) - A remote code execution vulnerability exists when Microsoft Windows OLE fails to properly validate user input. An attacker could exploit the vulnerability to execute malicious code. (CVE-2019-0885) - An elevation of privilege vulnerability exists when the Windows Kernel improperly handles key enumeration. An attacker who successfully exploited the vulnerability could gain elevated privileges on a targeted system. A locally authenticated attacker could exploit this vulnerability by running a specially crafted application. The security update addresses the vulnerability by helping to ensure that the Windows Kernel properly handles key enumeration. (CVE-2019-0881) - An elevation of privilege vulnerability exists in Microsoft Windows when Windows fails to properly handle certain symbolic links. An attacker who successfully exploited this vulnerability could potentially set certain items to run at a higher level and thereby elevate permissions. (CVE-2019-0936) - An spoofing vulnerability exists when Internet Explorer improperly handles URLs. An attacker who successfully exploited this vulnerability could trick a user by redirecting the user to a specially crafted website. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. (CVE-2019-0921) - A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system.

An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. (CVE-2019-0864) - A remote code execution vulnerability exists in Remote Desktop Services formerly known as Terminal Services when an unauthenticated attacker connects to the target system using RDP and sends specially crafted requests. This vulnerability is pre-authentication and requires no user interaction. An attacker who successfully exploited this vulnerability could execute arbitrary code on the target system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2019-0708) - An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2019-0758, CVE-2019-0882, CVE-2019-0961) - An information disclosure vulnerability exists when Internet Explorer improperly handles objects in memory.
