| スコープ | 影響 | 可能性 |
|---|---|---|
| Integrity Confidentiality Availability | Execute Unauthorized Code or Commands 注記：The header may contain a script that will get executed in the client's browser context, potentially resulting in a cross site scripting vulnerability or possibly an HTTP response splitting attack. | |
| Confidentiality | Read Application Data 注記：Attackers may be able to obtain sensitive information. |

潜在的な緩和策
Phases : Architecture and DesignCarefully control data that is being placed both in HTTP response headers and in the HTTP response body to ensure that no scripting syntax is present, taking various encodings into account. Perform output validation in order to filter/escape/encode unsafe data that is being passed from the server in an HTTP response header.
Phases : Architecture and Design
Disable script execution functionality in the clients' browser.
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.
