        More Info

        Server-Side Request Forgery (SSRF) occurs when attackers can coerce a server to perform arbitrary requests on their behalf.

        An SSRF vulnerability can either be basic or blind, depending on whether the server’s fetched data is directly returned in the web application’s response.
        The absence of the corresponding response for the coerced request on the application is not a barrier to exploitation and thus must be treated in the same way as basic SSRF.

        What is the potential impact?

        SSRF usually results in unauthorized actions or data disclosure in the vulnerable application or on a different system it can reach. Conditional to what is reachable, remote command execution can be achieved, although it often requires chaining with further exploitations.

        Information disclosure is SSRF’s core outcome. Depending on the extracted data, an attacker can perform a variety of different actions that can range from low to critical severity.

        Below are some real-world scenarios that illustrate some impacts of an attacker exploiting the vulnerability.

        Local file read to host takeover

        An attacker manipulates an application into performing a local request for a sensitive file, such as ~/.ssh/id_rsa, by using the File URI scheme file://.
        Once in possession of the SSH keys, the attacker establishes a remote connection to the system hosting the web application.

        Internal Network Reconnaissance

        An attacker enumerates internal accessible ports from the affected server or others to which the server can communicate by iterating over the port field in the URL http://127.0.0.1:{port}.
        Taking advantage of other supported URL schemas (dependent on the affected system), for example, gopher://127.0.0.1:3306, an attacker would be able to connect to a database service and perform queries on it.
