Hậu quả phổ biến

Phạm vi Tác động Khả năng xảy ra
Integrity
Confidentiality
Availability
Execute Unauthorized Code or Commands

Ghi chú: If one executes code at a known location, an attacker might be able to inject code there beforehand.
AvailabilityDoS: Crash, Exit, or Restart, Reduce Maintainability, Reduce Reliability

Ghi chú: 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

Ghi chú: 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.

Phương pháp phát hiện

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].
Hiệu quả : Moderate

Ghi chú ánh xạ lỗ hổng

Lý do : 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.
Bình luận : 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.
