일반적인 결과

범위	영향	가능성
Integrity Confidentiality Availability	Execute Unauthorized Code or Commands 참고: 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 참고: Attackers may be able to obtain sensitive information.

참고 자료	설명
CVE-2006-3918	Web server does not remove the Expect header from an HTTP request when it is reflected back in an error message, allowing a Flash SWF file to perform XSS attacks.

잠재적 완화 방법

Phases : Architecture and Design
Carefully 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.

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.
