Summary

An elevation of privilege vulnerability exists in Microsoft Windows where certain folders, with local service privilege, are vulnerable to symbolic link attack. An attacker who successfully exploited this vulnerability could potentially access unauthorized information. The update addresses this vulnerability by not allowing symbolic links in these scenarios., aka 'Microsoft Windows Elevation of Privilege Vulnerability'. This CVE ID is unique from CVE-2019-1082.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Symlink Attack
    An attacker positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name. The endpoint file may be either output or input. If the file is output, the result is that the endpoint is modified, instead of a file at the intended location. Modifications to the endpoint file may include appending, overwriting, corrupting, changing permissions, or other modifications. In some variants of this attack the attacker may be able to control the change to a file while in other cases they cannot. The former is especially damaging since the attacker may be able to grant themselves increased privileges or insert false information, but the latter can also be damaging as it can expose sensitive information or corrupt or destroy vital system or application files. Alternatively, the endpoint file may serve as input to the targeted application. This can be used to feed malformed input into the target or to cause the target to process different information, possibly allowing the attacker to control the actions of the target or to cause the target to expose information to the attacker. Moreover, the actions taken on the endpoint file are undertaken with the permissions of the targeted user or application, which may exceed the permissions that the attacker would normally have.
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

    It is, therefore, affected by multiple vulnerabilities :
    
      - A remote code execution vulnerability exists in .NET
        software when the software fails to check the source
        markup of a file. 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. An attacker

        allow arbitrary code execution; however, it could allow
        arbitrary code to be run if the attacker uses it in
        combination with another vulnerability (such as a remote
        code execution vulnerability or another elevation of
        privilege vulnerability) that is capable of leveraging
        the elevated privileges when code execution is
        attempted. (CVE-2019-0880)

        attacker who successfully exploited the vulnerability
        could gain the same user rights as the current user.
        (CVE-2019-1001)
    
      - 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. An attacker who

        successfully exploited the vulnerability could gain the
        same user rights as the current user.  (CVE-2019-1104)
    
      - An information disclosure vulnerability exists when
        DirectWrite 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,

        correcting how the Windows kernel handles objects in
        memory. (CVE-2019-1071)
    
      - An elevation of privilege vulnerability exists when the
        Windows kernel fails to properly handle objects in
        memory. An attacker who successfully exploited this
        vulnerability could run arbitrary code in kernel mode.

    It is, therefore, affected by multiple vulnerabilities :
    
      - An elevation of privilege vulnerability exists when
        DirectX improperly handles 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-2019-0999)
    
      - A remote code execution vulnerability exists in .NET
        software when the software fails to check the source
        markup of a file. 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. An attacker
        could then install programs; view, change, or delete
        data; or create new accounts with full user rights.
        (CVE-2019-1113)
    
      - A local elevation of privilege vulnerability exists in
        how splwow64.exe handles certain calls. An attacker who
        successfully exploited the vulnerability could elevate
        privileges on an affected system from low-integrity to
        medium-integrity. This vulnerability by itself 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 (such as a remote
        code execution vulnerability or another elevation of
        privilege vulnerability) that is capable of leveraging
        the elevated privileges when code execution is
        attempted. (CVE-2019-0880)
    
      - A denial of service vulnerability exists when Microsoft
        Hyper-V on a host server fails to properly validate
        input from a privileged user on a guest operating
        system.  (CVE-2019-0966)
    
      - A remote code execution vulnerability exists in the way
        that the Chakra scripting engine handles objects in
        memory in Microsoft Edge. The vulnerability could
        corrupt memory in such a way that an attacker could
        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-2019-1062, CVE-2019-1092,
        CVE-2019-1103, CVE-2019-1106, CVE-2019-1107)

        its memory. An attacker who successfully exploited this
        vulnerability could obtain information to further
        compromise the users system.  (CVE-2019-1108)
    
      - An information disclosure vulnerability exists when the
        win32k component improperly provides kernel information.
        An attacker who successfully exploited the vulnerability
        could obtain information to further compromise the users
        system.  (CVE-2019-1096)
    
      - An elevation of privilege vulnerability exists in the
        way Windows Error Reporting (WER) handles files. 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 administrator
        privileges.  (CVE-2019-1037)
    
      - A remote code execution vulnerability exists in the way
        the scripting engine handles objects in memory in
        Microsoft browsers. The vulnerability could corrupt
        memory in such a way that an attacker could 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-2019-1001)
    
      - A remote code execution vulnerability exists when
        Internet Explorer improperly accesses objects in memory.
        The vulnerability could corrupt memory in such a way

      - 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-2019-1104)
    
      - An information disclosure vulnerability exists when
        DirectWrite 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 DirectWrite handles objects in memory.
        (CVE-2019-1093, CVE-2019-1097)

        in memory. (CVE-2019-1094, CVE-2019-1095)
    
      - 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. An authenticated attacker could exploit this
        vulnerability by running a specially crafted
        application. The update addresses the vulnerability by
        correcting how the Windows kernel handles objects in
        memory. (CVE-2019-1071)
    
      - An elevation of privilege vulnerability exists when the
        Windows kernel 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-2019-1067)
    
      - An elevation of privilege exists in Windows Audio
        Service. An attacker who successfully exploited the
        vulnerability could run arbitrary code with elevated
        privileges.  (CVE-2019-1086, CVE-2019-1087,

    It is, therefore, affected by multiple vulnerabilities :
    
      - A remote code execution vulnerability exists in .NET
        software when the software fails to check the source
        markup of a file. 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. An attacker
        could then install programs; view, change, or delete
        data; or create new accounts with full user rights.
        (CVE-2019-1113)
    
      - A local elevation of privilege vulnerability exists in
        how splwow64.exe handles certain calls. An attacker who
        successfully exploited the vulnerability could elevate
        privileges on an affected system from low-integrity to
        medium-integrity. This vulnerability by itself 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 (such as a remote
        code execution vulnerability or another elevation of
        privilege vulnerability) that is capable of leveraging
        the elevated privileges when code execution is
        attempted. (CVE-2019-0880)
    
      - A denial of service vulnerability exists when Microsoft
        Hyper-V on a host server fails to properly validate
        input from a privileged user on a guest operating
        system.  (CVE-2019-0966)
    
      - A remote code execution vulnerability exists in the way
        that the Chakra scripting engine handles objects in
        memory in Microsoft Edge. The vulnerability could
        corrupt memory in such a way that an attacker could
        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-2019-1062, CVE-2019-1092,
        CVE-2019-1103, CVE-2019-1106, CVE-2019-1107)
    
      - An information disclosure vulnerability exists when the
        Windows RDP client improperly discloses the contents of
        its memory. An attacker who successfully exploited this
        vulnerability could obtain information to further
        compromise the users system.  (CVE-2019-1108)
    
      - An information disclosure vulnerability exists when the
        win32k component improperly provides kernel information.
        An attacker who successfully exploited the vulnerability
        could obtain information to further compromise the users
        system.  (CVE-2019-1096)
    
      - An elevation of privilege vulnerability exists in the
        way Windows Error Reporting (WER) handles files. 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 administrator
        privileges.  (CVE-2019-1037)
    
      - A remote code execution vulnerability exists in the way
        the scripting engine handles objects in memory in
        Microsoft browsers. The vulnerability could corrupt
        memory in such a way that an attacker could 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-2019-1001)
    
      - 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. An attacker who
        successfully exploited the vulnerability could gain the
        same user rights as the current user.  (CVE-2019-1063)
    
      - An elevation of privilege vulnerability exists in
        Microsoft Windows where certain folders, with local
        service privilege, are vulnerable to symbolic link
        attack. An attacker who successfully exploited this
        vulnerability could potentially access unauthorized
        information. The update addresses this vulnerability by
        not allowing symbolic links in these scenarios.
        (CVE-2019-1074)
    
      - An elevation of privilege vulnerability exists in the
        way that the dnsrslvr.dll handles objects in memory. An
        attacker who successfully exploited the vulnerability
        could execute code with elevated permissions.
        (CVE-2019-1090)
    
      - 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-2019-1104)
    
      - An information disclosure vulnerability exists when
        DirectWrite 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 DirectWrite handles objects in memory.
        (CVE-2019-1093, CVE-2019-1097)
    
      - 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-2019-1094, CVE-2019-1095)
    
      - 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. An authenticated attacker could exploit this
        vulnerability by running a specially crafted
        application. The update addresses the vulnerability by
        correcting how the Windows kernel handles objects in
        memory. (CVE-2019-1071)
    
      - An elevation of privilege vulnerability exists when the
        Windows kernel 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-2019-1067)
    
      - An elevation of privilege exists in Windows Audio
        Service. An attacker who successfully exploited the
        vulnerability could run arbitrary code with elevated

    It is, therefore, affected by multiple vulnerabilities :
    
      - An elevation of privilege vulnerability exists when
        DirectX improperly handles 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

        (CVE-2019-0999)
    
      - A remote code execution vulnerability exists in .NET
        software when the software fails to check the source
        markup of a file. 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. An attacker
        could then install programs; view, change, or delete
        data; or create new accounts with full user rights.
        (CVE-2019-1113)
    
      - A local elevation of privilege vulnerability exists in
        how splwow64.exe handles certain calls. An attacker who

        arbitrary code to be run if the attacker uses it in
        combination with another vulnerability (such as a remote
        code execution vulnerability or another elevation of
        privilege vulnerability) that is capable of leveraging
        the elevated privileges when code execution is
        attempted. (CVE-2019-0880)
    
      - A denial of service vulnerability exists when Microsoft

        (CVE-2019-1085)
    
      - A denial of service vulnerability exists when Microsoft
        Common Object Runtime Library improperly handles web
        requests. An attacker who successfully exploited this
        vulnerability could cause a denial of service against a
        .NET web application. A remote unauthenticated attacker
        could exploit this vulnerability by issuing specially
        crafted requests to the .NET application. The update
        addresses the vulnerability by correcting how the .NET
        web application handles web requests. (CVE-2019-1083)
    
      - An elevation of privilege vulnerability exists in
        rpcss.dll when the RPC service Activation Kernel
        improperly handles an RPC request.  (CVE-2019-1089)
    
      - 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-2019-1073)
    
      - A denial of service vulnerability exists when SymCrypt
        improperly handles a specially crafted digital
        signature. An attacker could exploit the vulnerability
        by creating a specially crafted connection or message.
        The security update addresses the vulnerability by
        correcting the way SymCrypt handles digital signatures.
        (CVE-2019-0865)
    
      - A remote code execution vulnerability exists in the way
        that the Windows Graphics Device Interface (GDI) handles
        objects in the 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-2019-1102)
    
      - An authentication bypass vulnerability exists in Windows
        Communication Foundation (WCF) and Windows Identity
        Foundation (WIF), allowing signing of SAML tokens with
        arbitrary symmetric keys. This vulnerability allows an
        attacker to impersonate another user, which can lead to
        elevation of privileges. The vulnerability exists in
        WCF, WIF 3.5 and above in .NET Framework, WIF 1.0
        component in Windows, WIF Nuget package, and WIF
        implementation in SharePoint. An unauthenticated
        attacker can exploit this by signing a SAML token with
        any arbitrary symmetric key. This security update
        addresses the issue by ensuring all versions of WCF and
        WIF validate the key used to sign SAML tokens correctly.
        (CVE-2019-1006)
    
      - An elevation of privilege vulnerability exists when
        Windows AppX Deployment Service (AppXSVC) improperly
        handles hard links. An attacker who successfully
        exploited this vulnerability could run processes in an
        elevated context. An attacker could then install
        programs; view, change or delete data.  (CVE-2019-1129,
        CVE-2019-1130)
    
      - An information disclosure vulnerability exists when
        Unistore.dll fails to properly handle objects in memory.
        An attacker who successfully exploited the vulnerability
        could potentially disclose memory contents of an
        elevated process.  (CVE-2019-1091)
    
      - A remote code execution vulnerability exists in the way
        that DirectWrite 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. 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
        DirectWrite handles objects in memory. (CVE-2019-1117,
        CVE-2019-1118, CVE-2019-1119, CVE-2019-1120,
        CVE-2019-1121, CVE-2019-1122, CVE-2019-1123,
        CVE-2019-1124, CVE-2019-1127, CVE-2019-1128)
      
      - An information disclosure vulnerability exists when
        certain central processing units (CPU) speculatively
        access memory. An attacker who successfully exploited
        the vulnerability could read privileged data across
        trust boundaries. (CVE-2019-1125)");
