+
+== Concept
+In a Server-Side Request Forgery (SSRF) attack, the attacker can abuse functionality on the server to read or update internal resources. The attacker can supply or a modify a URL which the code running on the server will read or submit data to, and by carefully selecting the URLs, the attacker may be able to read server configuration such as AWS metadata, connect to internal services like http enabled databases or perform post requests towards internal services which are not intended to be exposed.
+
+== Goals
+* The user will need to modify the URL.

+
+== Prevent
+To prevent SSRF vulnerabilities in web applications, it is recommended to adhere to the following guidelines:
+
+* Use a whitelist of allowed domains, resources and protocols from where the web server can fetch resources.
+* Any input accepted from the user should be validated and rejected if it does not match the positive specification expected.
+* If possible, do not accept user input in functions that control where the web server can fetch resources.
