Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

      - A remote code execution vulnerability exists in Remote
        Desktop Services formerly known as Terminal Services
        when an authenticated attacker abuses clipboard
        redirection. An attacker who successfully exploited this
        vulnerability could execute arbitrary code on the victim
        system. An attacker could then install programs; view,
        change, or delete data; or create new accounts with full
        user rights.  (CVE-2019-0887)
    
      - An elevation of privilege vulnerability exists in the
        way that the wlansvc.dll handles objects in memory. An
        attacker who successfully exploited the vulnerability
        could execute code with elevated permissions.
        (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)
    
      - 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-2019-1107)
    
      - 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 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 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)
        
      - 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)");

    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)
    
      - An elevation of privilege vulnerability exists in
        rpcss.dll when the RPC service Activation Kernel
        improperly handles an RPC request.  (CVE-2019-1089)
    
      - 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)

        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.

      - 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

        system. An attacker could then install programs; view,
        change, or delete data; or create new accounts with full
        user rights.  (CVE-2019-0887)
    
      - An elevation of privilege vulnerability exists in the
        way that the wlansvc.dll handles objects in memory. An
        attacker who successfully exploited the vulnerability
        could execute code with elevated permissions.
        (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)
    
      - 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

    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)

        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 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.

    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)
    
      - An information disclosure vulnerability exists when the

        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

      - 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)

        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
