According to the definition provided by OWASP, a SSRF attack enables an attacker to abuse a server’s functionality to read or update internal resources.

“The attacker can supply or 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,” OWASP explains.
Dubbed SSRF Dashboard, the new utility from Facebook features a simple interface that allows researchers to create unique internal endpoint URLs for targeting and then learn whether their URLs have been hit during an SSRF attempt.

Facebook encourages researchers who hunt for and discover SSRF vulnerabilities to include the ID of the SSRF attempt URL in their reports, along with the PoC.

“Server Side Request Forgery (SSRF) vulnerabilities are among the most difficult ones to find, given that external researchers aren’t able to detect the server’s vulnerable behavior in a direct manner,” Facebook notes.
