Configuration Management / Flash Cross-Domain Policy
Flash cross-domain policy is an IT vulnerability that affects web and API applications. According to the Common Weakness Enumeration (CWE) directory, this vulnerability is classified as CWE-918: Server-Side Request Forgery (SSRF). It occurs when a web application or API allows a malicious user to send unrestricted cross-domain requests to a server. This can allow the malicious user to gain access to unauthorized data or services. Additionally, the OWASP Testing Guide identifies this vulnerability as A9:2017-Server Side Request Forgery.
This vulnerability poses a significant risk to organizations, as it allows a malicious user to access sensitive data or perform unauthorized actions. If the malicious user has access to the server, they can exploit the vulnerability to gain access to the server’s resources. This can lead to damage to the server, disruption of services, and leakage of confidential data.
In order to mitigate this vulnerability, organizations should ensure that all cross-domain requests are restricted and validated. This can be done by implementing an access control mechanism that limits the types of requests that can be sent to the server. Additionally, organizations should ensure that all requests are properly authenticated and authorized before being processed.
