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.

"The remote Windows host is missing security update 4507456
or cumulative update 4507449. It is, therefore, affected by
multiple vulnerabilities :

  - 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)

  - 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 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 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)

  - 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 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, CVE-2019-1098,
    CVE-2019-1099, CVE-2019-1100, CVE-2019-1101,
    CVE-2019-1116)

  - 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)

  - 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 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 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 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)

  - 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-2019-1132)

  - An elevation of privilege exists in Windows Audio
    Service. An attacker who successfully exploited the
    vulnerability could run arbitrary code with elevated
    privileges.  (CVE-2019-1088)

  - 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
    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)

  - A remote code execution vulnerability exists in the way
    that the scripting engine handles objects in memory in
    Internet Explorer. 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-2019-1004, CVE-2019-1056, CVE-2019-1059)

  - An elevation of privilege vulnerability exists in
    Microsoft Windows where a certain dll, with Local
    Service privilege, is vulnerable to race planting a
    customized dll. An attacker who successfully exploited
    this vulnerability could potentially elevate privilege
    to SYSTEM. The update addresses this vulnerability by
    requiring system privileges for a certain DLL.
    (CVE-2019-1082)

  - 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)
    
  - 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)");
