Summary

The Windows Server DHCP service in Windows Server 2012 Gold and R2, and Windows Server 2016 allows an attacker to either run arbitrary code on the DHCP failover server or cause the DHCP service to become nonresponsive, due to a memory corruption vulnerability in the Windows Server DHCP service, aka "Windows DHCP Server Remote Code Execution Vulnerability".

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    "The remote Windows host is missing security update 4038793
    or cumulative update 4038792. It is, therefore, affected by
    multiple vulnerabilities :
    
      - A race condition that could lead to a remote code
        execution vulnerability exists in NetBT Session Services
        when NetBT fails to maintain certain sequencing
        requirements. (CVE-2017-0161)
    
      - A spoofing vulnerability exists in Microsoft's
        implementation of the Bluetooth stack. An attacker who
        successfully exploited this vulnerability could perform
        a man-in-the-middle attack and force a user's computer
        to unknowingly route traffic through the attacker's
        computer. The attacker can then monitor and read the
        traffic before sending it on to the intended recipient.
        (CVE-2017-8628)
    
      - An elevation of privilege vulnerability exists in
        Windows when the Windows kernel-mode driver fails to
        properly handle objects in memory. An attacker who
        successfully exploited this vulnerability could run
        arbitrary code in kernel mode. An attacker could then
        install programs; view, change, or delete data; or
        create new accounts with full user rights. To exploit
        this vulnerability, an attacker would first have to log
        on to the system. An attacker could then run a specially
        crafted application that could exploit the vulnerability
        and take control of an affected system. The update
        addresses this vulnerability by correcting how the
        Windows kernel-mode driver handles objects in memory.
        (CVE-2017-8675)
    
      - An information disclosure vulnerability exists in the
        way that the Windows Graphics Device Interface (GDI)
        handles objects in memory, allowing an attacker to
        retrieve information from a targeted system. By itself,
        the information disclosure does not allow arbitrary code
        execution; however, it could allow arbitrary code to be
        run if the attacker uses it in combination with another
        vulnerability. (CVE-2017-8676)
    
      - A remote code execution vulnerability exists when the
        Windows font library improperly handles specially
        crafted embedded fonts. An attacker who successfully
        exploited this vulnerability could take control of the
        affected system. An attacker could then install
        programs; view, change, or delete data; or create new
        accounts with full user rights. (CVE-2017-8682)
    
      - An information disclosure vulnerability exists when the
        Microsoft Windows Graphics Component improperly handles
        objects in memory. An attacker who successfully
        exploited the vulnerability could obtain information to
        further compromise the users system. (CVE-2017-8683)
    
      - A information disclosure vulnerability exists when the
        Windows GDI+ component improperly discloses kernel
        memory addresses. An attacker who successfully exploited
        the vulnerability could obtain information to further
        compromise the users system. 
        (CVE-2017-8677, CVE-2017-8680, CVE-2017-8681,
        CVE-2017-8684)
    
      - A memory corruption vulnerability exists in the Windows
        Server DHCP service when an attacker sends specially
        crafted packets to a DHCP failover server. An attacker
        who successfully exploited the vulnerability could
        either run arbitrary code on the DHCP failover server or
        cause the DHCP service to become nonresponsive. To
        exploit the vulnerability, an attacker could send a
        specially crafted packet to a DHCP server. However, the
        DHCP server must be set to failover mode for the attack
        to succeed. The security update addresses the
        vulnerability by correcting how DHCP failover servers
        handle network packets. (CVE-2017-8686)
    
      - An Information disclosure vulnerability exists in
        Windows kernel that could allow an attacker to retrieve
        information that could lead to a Kernel Address Space
        Layout Randomization (KASLR) bypass. An attacker who
        successfully exploited this vulnerability could retrieve
        the memory address of a kernel object. (CVE-2017-8687)
    
      - An information disclosure vulnerability exists in the
        way that the Windows Graphics Device Interface+ (GDI+)
        handles objects in memory, allowing an attacker to
        retrieve information from a targeted system. By itself,
        the information disclosure does not allow arbitrary code
        execution; however, it could allow arbitrary code to be
        run if the attacker uses it in combination with another
        vulnerability. (CVE-2017-8688)
    
      - A remote code execution vulnerability exists due to the
        way Windows Uniscribe handles objects in memory. An
        attacker who successfully exploited this vulnerability
        could take control of the affected system. An attacker
        could then install programs; view, change, or delete
        data; or create new accounts with full user rights.
        (CVE-2017-8692)
    
      - An information disclosure vulnerability exists when
        Windows Uniscribe 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 update addresses the vulnerability by correcting how
        Windows Uniscribe handles objects in memory.
        (CVE-2017-8695)
    
      - A remote code execution vulnerability exists when
        Windows Shell does not properly validate file copy
        destinations. An attacker who successfully exploited the
        vulnerability could run arbitrary code in the context of
        the current user.
        (CVE-2017-8699)
    
      - An information disclosure vulnerability exists when the
        Windows kernel fails to properly initialize a memory
        address, allowing an attacker to retrieve information
        that could lead to a Kernel Address Space Layout
        Randomization (KASLR) bypass. An attacker who
        successfully exploited this vulnerability could retrieve
        the base address of the kernel driver from a compromised
        process. (CVE-2017-8708)
    
      - An information disclosure vulnerability exists when
        Windows Hyper-V on a host operating system fails to
        properly validate input from an authenticated user on a
        guest operating system. (CVE-2017-8707, CVE-2017-8713)
    
      - A remote code execution vulnerability exists in the VM
        Host Agent Service of Remote Desktop Virtual Host role
        when it fails to properly validate input from an
        authenticated user on a guest operating system. To
        exploit the vulnerability, an attacker could issue a
        specially crafted certificate on the guest operating
        system that could cause the VM host agent service on the
        host operating system to execute arbitrary code. The
        Remote Desktop Virtual Host role is not enabled by
        default. An attacker who successfully exploited the
        vulnerability could execute arbitrary code on the host
        operating system. The security update addresses the
        vulnerability by correcting how VM host agent service
        validates guest operating system user input.
        (CVE-2017-8714)
    
      - An information disclosure vulnerability exists when the
        Windows kernel improperly handles objects in memory. An
        attacker who successfully exploited this vulnerability
        could obtain information to further compromise the users
        system. (CVE-2017-8678, CVE-2017-8679, CVE-2017-8709,
        CVE-2017-8719)
    
      - An elevation of privilege vulnerability exists in
        Windows when the Win32k component fails to properly
        handle objects in memory. An attacker who successfully
        exploited this vulnerability could run arbitrary code in
        kernel mode. An attacker could then install programs;
        view, change, or delete data; or create new accounts
        with full user rights. (CVE-2017-8720)
    
      - A spoofing vulnerability exists when Internet Explorer
        improperly handles specific HTML content. An attacker
        who successfully exploited this vulnerability could
        trick a user into believing that the user was visiting a
        legitimate website. The specially crafted website could
        either spoof content or serve as a pivot to chain an
        attack with other vulnerabilities in web services. To
        exploit the vulnerability, the user must either browse
        to a malicious website or be redirected to it. In an
        email attack scenario, an attacker could send an email
        message in an attempt to convince the user to click a
        link to the malicious website. (CVE-2017-8733)
    
      - An information disclosure vulnerability exists in
        Microsoft browsers due to improper parent domain
        verification in certain functionality. An attacker who
        successfully exploited the vulnerability could obtain
        specific information that is used in the parent domain.
        (CVE-2017-8736)
    
      - A remote code execution vulnerability exists when
        Microsoft Windows PDF Library improperly handles objects
        in memory. The vulnerability could corrupt memory in a
        way that enables 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-2017-8728, CVE-2017-8737)
    
      - A remote code execution vulnerability exists in the way
        that Microsoft browser JavaScript engines render content
        when handling objects in memory. The vulnerability could
        corrupt memory in such a way that an attacker could
        execute arbitrary code in the context of the current
        user. (CVE-2017-8741, CVE-2017-8748)
    
      - A remote code execution vulnerability exists when
        Internet Explorer improperly accesses objects in memory.
        The vulnerability could corrupt memory in such a way
        that an attacker could execute arbitrary code in the
        context of the current user. (CVE-2017-8747,
        CVE-2017-8749)
    
      - A remote code execution vulnerability exists when
        Microsoft browsers improperly access objects in memory.
        The vulnerability could corrupt memory in such a way
        that an attacker could execute arbitrary code in the
        context of the current user. (CVE-2017-8750)
    
      - A remote code execution vulnerability exists when
        Microsoft .NET Framework processes untrusted input. An
        attacker who successfully exploited this vulnerability
        in software using the .NET framework could take control
        of an affected system. An attacker could then install
        programs; view, change, or delete data; or create new
        accounts with full user rights. (CVE-2017-8759)
        
      - An information disclosure vulnerability exists in
        Microsoft browsers in the scripting engines due to
        improper handling of objects in memory. An
        unauthenticated, remote attacker can exploit this, by
        convincing a user to visit a specially crafted website,
        to disclose files on a user's computer. (CVE-2017-8529)");

    descriptionThe remote Windows host is missing security update 4038786 or cumulative update 4038799. It is, therefore, affected by multiple vulnerabilities : - A race condition that could lead to a remote code execution vulnerability exists in NetBT Session Services when NetBT fails to maintain certain sequencing requirements. (CVE-2017-0161) - An elevation of privilege vulnerability exists in Windows when the Windows kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2017-8675) - An information disclosure vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory, allowing an attacker to retrieve information from a targeted system. By itself, the information disclosure does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability. (CVE-2017-8676) - A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts.

        way that the Windows Graphics Device Interface+ (GDI+)
        handles objects in memory, allowing an attacker to
        retrieve information from a targeted system. By itself,
        the information disclosure does not allow arbitrary code
        execution; however, it could allow arbitrary code to be
        run if the attacker uses it in combination with another
        vulnerability. (CVE-2017-8688)
    
      - A remote code execution vulnerability exists due to the
        way Windows Uniscribe handles objects in memory. An
        attacker who successfully exploited this vulnerability
        could take control of the affected system. An attacker

      - A remote code execution vulnerability exists in the VM
        Host Agent Service of Remote Desktop Virtual Host role
        when it fails to properly validate input from an
        authenticated user on a guest operating system. To
        exploit the vulnerability, an attacker could issue a
        specially crafted certificate on the guest operating
        system that could cause the VM host agent service on the
        host operating system to execute arbitrary code. The
        Remote Desktop Virtual Host role is not enabled by
        default. An attacker who successfully exploited the
        vulnerability could execute arbitrary code on the host
        operating system. The security update addresses the
        vulnerability by correcting how VM host agent service
        validates guest operating system user input.

    "The remote Windows host is missing security update 4038782.
    It is, therefore, affected by multiple vulnerabilities :
    
      - A race condition that could lead to a remote code
        execution vulnerability exists in NetBT Session Services
        when NetBT fails to maintain certain sequencing
        requirements. (CVE-2017-0161)
    
      - A vulnerability exists when Microsoft Edge improperly
        accesses objects in memory. The vulnerability could
        corrupt memory in such a way that an attacker could
        execute arbitrary code in the context of the current
        user. (CVE-2017-11766)
    
      - A spoofing vulnerability exists in Microsoft's
        implementation of the Bluetooth stack. An attacker who
        successfully exploited this vulnerability could perform
        a man-in-the-middle attack and force a user's computer
        to unknowingly route traffic through the attacker's
        computer. The attacker can then monitor and read the
        traffic before sending it on to the intended recipient.
        (CVE-2017-8628)
    
      - An information disclosure vulnerability exists when
        Microsoft Edge improperly handles clipboard events. For
        an attack to be successful, an attacker must persuade a
        user to visit a malicious website and leave it open
        during clipboard activities. The update addresses the
        vulnerability by changing how Microsoft Edge handles
        clipboard events in the browser. (CVE-2017-8643)
    
      - An elevation of privilege vulnerability exists in
        Windows when the Windows kernel-mode driver fails to
        properly handle objects in memory. An attacker who
        successfully exploited this vulnerability could run
        arbitrary code in kernel mode. An attacker could then
        install programs; view, change, or delete data; or
        create new accounts with full user rights. To exploit
        this vulnerability, an attacker would first have to log
        on to the system. An attacker could then run a specially
        crafted application that could exploit the vulnerability
        and take control of an affected system. The update
        addresses this vulnerability by correcting how the
        Windows kernel-mode driver handles objects in memory.
        (CVE-2017-8675)
    
      - An information disclosure vulnerability exists in the
        way that the Windows Graphics Device Interface (GDI)
        handles objects in memory, allowing an attacker to
        retrieve information from a targeted system. By itself,
        the information disclosure does not allow arbitrary code
        execution; however, it could allow arbitrary code to be
        run if the attacker uses it in combination with another
        vulnerability. (CVE-2017-8676)
    
      - A information disclosure vulnerability exists when the
        Windows GDI+ component improperly discloses kernel
        memory addresses. An attacker who successfully exploited
        the vulnerability could obtain information to further
        compromise the users system.

      - A remote code execution vulnerability exists when the
        Windows font library improperly handles specially
        crafted embedded fonts. An attacker who successfully
        exploited this vulnerability could take control of the
        affected system. An attacker could then install
        programs; view, change, or delete data; or create new
        accounts with full user rights.(CVE-2017-8682)
    
      - An information disclosure vulnerability exists when the
        Microsoft Windows Graphics Component improperly handles
        objects in memory. An attacker who successfully
        exploited the vulnerability could obtain information to
        further compromise the users system.(CVE-2017-8683)
    
      - A memory corruption vulnerability exists in the Windows
        Server DHCP service when an attacker sends specially
        crafted packets to a DHCP failover server. An attacker
        who successfully exploited the vulnerability could
        either run arbitrary code on the DHCP failover server or
        cause the DHCP service to become nonresponsive.
        (CVE-2017-8686)
    
      - An Information disclosure vulnerability exists in
        Windows kernel that could allow an attacker to retrieve
        information that could lead to a Kernel Address Space
        Layout Randomization (KASLR) bypass. An attacker who
        successfully exploited this vulnerability could retrieve
        the memory address of a kernel object.(CVE-2017-8687)
    
      - An information disclosure vulnerability exists in the
        way that the Windows Graphics Device Interface+ (GDI+)
        handles objects in memory, allowing an attacker to
        retrieve information from a targeted system. By itself,
        the information disclosure does not allow arbitrary code
        execution; however, it could allow arbitrary code to be
        run if the attacker uses it in combination with another
        vulnerability.(CVE-2017-8688)
    
      - A remote code execution vulnerability exists due to the
        way Windows Uniscribe handles objects in memory. An
        attacker who successfully exploited this vulnerability
        could take control of the affected system. An attacker
        could then install programs; view, change, or delete
        data; or create new accounts with full user rights.
        (CVE-2017-8692)
    
      - An information disclosure vulnerability exists when
        Windows Uniscribe improperly discloses the contents of
        its memory. An attacker who successfully exploited the
        vulnerability could obtain information to further
        compromise the users system.
        (CVE-2017-8695)
    
      - A remote code execution vulnerability exists when
        Windows Shell does not properly validate file copy
        destinations. An attacker who successfully exploited the
        vulnerability could run arbitrary code in the context of
        the current user. If the current user is logged on with
        administrative user rights, an attacker could take
        control of the affected system.
        (CVE-2017-8699)
    
      - An elevation of privilege vulnerability exists in
        Windows Error Reporting (WER) when WER handles and
        executes files. The vulnerability could allow elevation
        of privilege if an attacker can successfully exploit it.
        An attacker who successfully exploited the vulnerability
        could gain greater access to sensitive information and
        system functionality.
        (CVE-2017-8702)
    
      - A denial of service vulnerability exists when Microsoft
        Hyper-V Virtual PCI on a host server fails to properly
        validate input from a privileged user on a guest
        operating system.

      - An information disclosure vulnerability exists when the
        Windows kernel fails to properly initialize a memory
        address, allowing an attacker to retrieve information
        that could lead to a Kernel Address Space Layout
        Randomization (KASLR) bypass. An attacker who
        successfully exploited this vulnerability could retrieve
        the base address of the kernel driver from a compromised
        process. (CVE-2017-8708)
    
      - An information disclosure vulnerability exists when
        Windows Hyper-V on a host operating system fails to
        properly validate input from an authenticated user on a
