Performing Blind SSRF Exploitation

When to Use

• When testing URL/webhook input parameters where server-side responses are not reflected
• During assessment of applications that fetch external resources (avatars, previews, imports)
• When testing PDF generators, image processors, or document converters for SSRF
• During cloud security assessments to detect metadata endpoint access
• When evaluating webhook functionality and URL validation implementations

Prerequisites

• Burp Suite Professional with Burp Collaborator for OOB detection
• interact.sh or webhook.site for external callback monitoring
• Understanding of SSRF attack vectors and internal network enumeration
• Knowledge of cloud metadata endpoints (AWS, GCP, Azure)
• VPS or controlled server for advanced exploitation callback handling
• Python with requests library for automation scripts
