잠재적 완화 방법

Phases : Architecture and Design
Protect information stored in cache.
Phases : Implementation
Use a restrictive caching policy for forms and web pages that potentially contain sensitive information, such as "no-cache" in the Cache-Control header.
Phases : Architecture and Design
Do not store unnecessarily sensitive information in the cache.
Phases : Architecture and Design
Consider using encryption in the cache.

탐지 방법

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.)

취약점 매핑 메모

근거 : 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.
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.
