CORS Header

Mon, 01 Jan 0001 00:00:00 +0000

Cross-Origin Resource Sharing (CORS) is an HTTP-header based mechanism that allows a server to indicate any other origins (domain, scheme, or port) than its own from which a browser should permit loading of resources. It relaxes the Same-Origin Policy (SOP).

CORS Misconfiguration

Mon, 01 Jan 0001 00:00:00 +0000

This CORS misconfiguration could allow an attacker to perform AJAX queries to the vulnerable website from a malicious page loaded by the victim’s user agent. In order to perform authenticated AJAX queries, the server must specify the header “Access-Control-Allow-Credentials: true” and the “Access-Control-Allow-Origin” header must be set to null or the malicious page’s domain. Even if this misconfiguration doesn’t allow authenticated AJAX requests, unauthenticated sensitive content can still be accessed (e.g intranet websites). A malicious page can belong to a malicious website but also a trusted website with flaws (e.g XSS, support of HTTP without TLS allowing code injection through MITM, etc).
