취약점 매핑 메모

근거 : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
댓글 : 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.

관련 공격 패턴

CAPEC ID	공격 패턴 이름
CAPEC-150	Collect Data from Common Resource Locations An adversary exploits well-known locations for resources for the purposes of undermining the security of the target. In many, if not most systems, files and resources are organized in a default tree structure. This can be useful for adversaries because they often know where to look for resources or files that are necessary for attacks. Even when the precise location of a targeted resource may not be known, naming conventions may indicate a small area of the target machine's file tree where the resources are typically located. For example, configuration files are normally stored in the /etc director on Unix systems. Adversaries can take advantage of this to commit other types of attacks.
CAPEC-204	Lifting Sensitive Data Embedded in Cache An adversary examines a target application's cache, or a browser cache, for sensitive information. Many applications that communicate with remote entities or which perform intensive calculations utilize caches to improve efficiency. However, if the application computes or receives sensitive information and the cache is not appropriately protected, an attacker can browse the cache and retrieve this information. This can result in the disclosure of sensitive information.
CAPEC-37	Retrieve Embedded Sensitive Data An attacker examines a target system to find sensitive data that has been embedded within it. This information can reveal confidential contents, such as account numbers or individual keys/credentials that can be used as an intermediate step in a larger attack.
CAPEC-545	Pull Data from System Resources An adversary who is authorized or has the ability to search known system resources, does so with the intention of gathering useful information. System resources include files, memory, and other aspects of the target system. In this pattern of attack, the adversary does not necessarily know what they are going to find when they start pulling data. This is different than CAPEC-150 where the adversary knows what they are looking for due to the common location.
