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. | |
| Availability | DoS: 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. | |
Các biện pháp giảm thiểu tiềm năng
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.
