スコープ	影響	可能性
Integrity Confidentiality Availability	Execute Unauthorized Code or Commands 注記：If one executes code at a known location, an attacker might be able to inject code there beforehand.
Availability	DoS: Crash, Exit, or Restart, Reduce Maintainability, Reduce Reliability 注記：If the code is ported to another platform or environment, the pointer is likely to be invalid and cause a crash.
Confidentiality Integrity	Read Memory, Modify Memory 注記：The data at a known pointer location can be easily read or influenced by an attacker.

Phases : Implementation
Never set a pointer to a fixed address.

検出方法

Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)

Automated Dynamic Analysis

Use tools that are integrated during compilation to insert runtime error-checking mechanisms related to memory safety errors, such as AddressSanitizer (ASan) for C/C++ [REF-1518].
有効性 : Moderate

脆弱性マッピングノート

理由 : 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.
コメント : 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.
