名称: Improper Address Validation in IOCTL with METHOD_NEITHER I/O Control Code
The product defines an IOCTL that uses METHOD_NEITHER for I/O, but it does not validate or incorrectly validates the addresses that are provided.

| 影响范围 | 影响 | 可能性 |
|---|---|---|
| Integrity Availability Confidentiality | Modify Memory, Read Memory, Execute Unauthorized Code or Commands, DoS: Crash, Exit, or Restart 注意： If validation is missing or incorrect, an attacker can supply arbitrary memory addresses for memory that belongs to another process or user. If the attacker can control the contents that the IOCTL writes, it may lead to code execution at high privilege levels. At the least, a crash can occur. |

CVE-2007-5756 | Chain: device driver for packet-capturing software allows access to an unintended IOCTL with resultant array index error. |
潜在缓解措施
Phases : ImplementationIf METHOD_NEITHER is required for the IOCTL, then ensure that all user-space addresses are properly validated before they are first accessed. The ProbeForRead and ProbeForWrite routines are available for this task. Also properly protect and manage the user-supplied buffers, since the I/O Manager does not do this when METHOD_NEITHER is being used. See References.
Phases : Architecture and Design
If possible, avoid using METHOD_NEITHER in the IOCTL and select methods that effectively control the buffer size, such as METHOD_BUFFERED, METHOD_IN_DIRECT, or METHOD_OUT_DIRECT.
Phases : Architecture and Design // Implementation
If the IOCTL is part of a driver that is only intended to be accessed by trusted users, then use proper access control for the associated device or device namespace. See References.
漏洞映射说明
依据 : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.备注 : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
