Steal Secrets From The Web: Master Parameter Fuzzing | Recon Part 9
Methods to parse hidden/secret parameters from the target
Hi geeks, it4chis3c (Twitter) came-up with another bounty earning write-up in the Bug Bounty Hunting Series:

Why Parameters Matter
Parameter extraction/parsing is the process of identifying and analyzing parameters (e.g., ?id=123
, POST data, headers) in web applications to uncover vulnerabilities. Parameters are often the entry point for attacks like SQLi, XSS, SSRF, and IDOR. Missing a parameter can mean missing a critical bug. This write-up combines theory, tools, and secret tips to level up your recon game.
- Attack Surface: Parameters define how data flows between client and server.
- Hidden Endpoints: Parameters like
debug=true
oradmin=1
often expose hidden functionality. - Input Validation Flaws: Misconfigured parameters are low-hanging fruit for exploitation.
