SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the common gap in basic SSRF detection by providing expert-level techniques to exploit Server-Side Request Forgery vulnerabilities that are often missed during standard security assessments, including advanced filter bypasses, cloud metadata access, and full exploitation chains to compromise internal services.

Core Features & Use Cases

  • Comprehensive SSRF Playbook: Covers URL filter bypass, protocol abuse (gopher, dict, file), blind SSRF detection, and chaining to RCE via internal services like Redis and Docker.
  • Cloud Metadata Exploitation: Includes pre-built payloads for AWS, GCP, Azure, Alibaba Cloud, and Kubernetes metadata endpoints to steal credentials and sensitive cloud resources.
  • Real-World CVE Chains: Provides step-by-step exploitation guides for public SSRF vulnerabilities including WebLogic SSRF (CVE-2014-4210) and Kubernetes SSRF (CVE-2020-8555/8562).
  • Use Case: Use this Skill during authorized penetration tests of web applications that fetch remote URLs, cloud-hosted services, or internal network-facing applications to identify unauthorized access risks.

Quick Start

Use the ssrf-server-side-request-forgery skill to test the target application's URL input parameter for SSRF vulnerabilities, including checking for accessible cloud metadata endpoints and exposed internal services.

FAQPage Schema
How do I test for SSRF vulnerabilities in web applications that fetch remote URLs?

SSRF testing involves injecting internal URLs or cloud metadata endpoints into URL fetch parameters to detect unauthorized resource access. This Skill automates detecting Server-Side Request Forgery by testing target applications for accessible internal services and exposed cloud metadata endpoints during authorized penetration tests.

What is the best way to bypass URL filters when exploiting SSRF?

Bypassing SSRF URL filters requires techniques like protocol abuse using gopher, dict, or file schemes to access restricted internal resources. This Skill provides an exploitation playbook covering various filter bypass methods and protocol abuse techniques to reach internal services that standard assessments often miss.

Can I access AWS or GCP cloud metadata endpoints through an SSRF attack?

Yes, SSRF attacks can access AWS, GCP, Azure, and Alibaba Cloud metadata endpoints to steal cloud credentials and sensitive resources. This Skill includes pre-built payloads specifically targeting cloud metadata services and Kubernetes APIs to extract unauthorized cloud configuration data.

How does blind SSRF detection work when the application does not return responses?

Blind SSRF detection identifies vulnerabilities by monitoring out-of-band interactions or timing delays when the target application processes injected internal URLs. This Skill covers blind detection techniques alongside methods to chain SSRF into remote code execution via internal services like Redis and Docker.

How do I chain SSRF to RCE using internal services like Redis or Docker?

Chaining SSRF to RCE exploits internal services by abusing protocols like gopher to send crafted commands to Redis or Docker APIs. This Skill provides step-by-step exploitation guides for compromising internal services and chaining public vulnerabilities like WebLogic SSRF to achieve remote code execution.

Does this Skill cover exploiting known CVEs like WebLogic or Kubernetes SSRF?

Yes, it provides step-by-step exploitation guides for public Server-Side Request Forgery vulnerabilities including WebLogic SSRF (CVE-2014-4210) and Kubernetes SSRF (CVE-2020-8555/8562). These real-world CVE chains demonstrate how to compromise internal services during authorized security testing.
