What its author says it does

Copied from the file, not written here

Test for Server-Side Request Forgery vulnerabilities by probing cloud metadata endpoints, internal network services, and protocol handlers through user-controllable URL parameters. Tests AWS/GCP/Azure metadata APIs (169.254.169.254), internal port scanning via HTTP, URL scheme bypass techniques, and DNS rebinding detection.

When to Use

  • When conducting security assessments that involve performing ssrf vulnerability exploitation
  • When following incident response procedures for related security events
  • When performing scheduled security testing or auditing activities
  • When validating security controls through hands-on testing

Prerequisites

  • Familiarity with security operations concepts and tools
  • Access to a test or lab environment for safe execution
  • Python 3.8+ with required dependencies installed
  • Appropriate authorization for any testing activities

Instructions

  1. Install dependencies: pip install requests
  2. Identify URL parameters in the target application that accept URLs or hostnames.
  3. Test SSRF payloads:
    • Cloud metadata: http://169.254.169.254/latest/meta-data/
    • Internal services: http://127.0.0.1:port/, http://10.0.0.1/
    • Protocol handlers: file:///etc/passwd, gopher://, dict://
    • Bypass techniques: IP encoding, DNS rebinding, URL redirects
  4. Analyze responses for information disclosure or internal access confirmation.
  5. Generate a vulnerability assessment report.
# For authorized penetration testing and lab environments only
python scripts/agent.py --target-url https://app.example.com/fetch?url= --output ssrf_report.json

Examples

AWS Metadata SSRF

GET /fetch?url=http://169.254.169.254/latest/meta-data/iam/security-credentials/

If the response contains AWS credentials (AccessKeyId, SecretAccessKey), SSRF is confirmed with critical impact.
