偵測方法
Black Box
This issue might not be detected if testing is performed using a web browser, because the browser might obey the redirect and move the user to a different page before the application has produced outputs that indicate something is amiss.漏洞對應備注
理由說明 : 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.備註 : 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.
