|---|---|---|
| Confidentiality | Read Application Data 注記：Browsers often store information in a client-side cache, which can leave behind sensitive information for other users to find and exploit, such as passwords or credit card numbers. The locations at most risk include public terminals, such as those in libraries and Internet cafes. |

潜在的な緩和策
Phases : Architecture and DesignProtect 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.
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.)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.

| 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. |
