A fully blind SSRF means #1 asynchronous processing #2 no DNS resolution. Intro. Blind SSRF with Shellshock exploitation. An attacker overrides or adds the HTTP GET/POST parameters by injecting query string delimiters. To solve the lab, use this functionality to perform a blind SSRF attack against an internal server in the 192.168.0.X range.
If #1 isn't true, delays can be used (open vs closed ports, TCP timeouts on DROP rules, /dev/random vs /dev/urandom ...). LAN-Based Blind SSRF Attack Primitive for Windows Systems (switcheroo) - initblog.

Let’s say you go to a website, fill out your profile, and get to the “Upload Profile Picture” step. Another avenue for exploiting blind SSRF vulnerabilities is to induce the application to connect to a system under the attacker's control, and return malicious responses to the HTTP client that makes the connection. Web Application Firewall CRS rule groups and rules. This site uses analytics software which fetches the URL specified in the Referer header when a product page is loaded.

Via HPP it may be possible to override existing hardcoded HTTP parameters, modify the application behaviors, access and, potentially exploit, uncontrollable variables, and bypass input validation checkpoints and WAF rules.
Application Gateway web application firewall (WAF) protects web applications from common vulnerabilities and exploits. There’s lots of information about it, but here is my quick summary.
