SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Blind injection scenarios are hard to prove when outputs are not reflected or visible. This skill provides structured methods to detect and prove blind injection surfaces using OOB callbacks, time-based delays, and boolean differences within authorized bug bounty engagements.

Core Features & Use Cases

  • Systematic detection of blind injection surfaces where input is processed server-side but no output is observed, or the response is identical across payloads.
  • Step-by-step payload strategies for blind SQL injection (time-based and boolean-based), blind SSRF, blind XXE, blind Command Injection, and blind XSS, including OOB infrastructure setup and verification criteria.
  • Guidance on evidence collection, callback verification, and escalation paths for robust proof of concepts in production-like targets.

Quick Start

Begin a blind-injection assessment by identifying surfaces and selecting an initial payload strategy.

FAQPage Schema
How do I prove blind SQL injection when the database output is not reflected in the HTTP response?

Prove blind SQL injection by using boolean-based differences or time-based delays to infer query execution. This skill provides structured payload workflows and verification criteria to systematically detect and document these blind injection surfaces.

What is the best way to detect blind SSRF and blind XXE without visible server responses?

Detect blind SSRF and blind XXE using out-of-band (OOB) callback infrastructure. This skill guides you through setting up external listeners to capture DNS or HTTP interactions, verifying server-side processing when responses are identical across payloads.

How to verify out-of-band (OOB) callbacks during a blind injection bug bounty assessment?

Verify OOB callbacks during a blind injection assessment by configuring external infrastructure to log DNS and HTTP interactions. This skill provides guidance on evidence collection, callback verification, and escalation paths for robust proof of concepts.

Can I use time-based payloads to find blind command injection across different database management systems?

Yes, you can use time-based payloads to find blind command injection across multiple DBMSs. This skill implements cross-technique payload variants and detection signals to identify timing differences in authorized bug bounty engagements.

Does blind XSS require special infrastructure setup to confirm execution on target endpoints?

Blind XSS requires external infrastructure setup to confirm execution when input is processed without visible output. This skill provides payload strategies and OOB verification criteria to capture callback evidence from production-like targets.

When should I not use boolean-based techniques for blind injection detection?

Avoid boolean-based techniques for blind injection detection when server responses are identical across all payloads or lack measurable differences. In these scenarios, switch to time-based delays or OOB callbacks to verify server-side processing.
