API Reference — Performing HTTP Parameter Pollution Attack

Libraries Used

  • requests: Send HTTP requests with duplicate/encoded parameters
  • urllib.parse: URL encoding and parameter manipulation

CLI Interface

python agent.py precedence --url <target> [--param id]
python agent.py test --url <target> [--method GET|POST]
python agent.py waf --url <target> --param <name> --value <blocked_value>

Core Functions

test_parameter_precedence(url, param_name, headers) — Detect server parameter handling

Sends duplicate parameters to determine if server uses FIRST, LAST, BOTH, or UNKNOWN value. Tests three value pairs to establish consistent behavior.

test_hpp_payloads(url, method, headers) — Execute HPP payload suite

Three categories of payloads:

  • duplicate_param: Basic duplicate parameter injection
  • encoding_bypass: URL-encoded, null byte, CRLF injection
  • array_syntax: PHP arrays, comma-separated, indexed arrays

Compares responses against baseline to detect anomalies (status/length changes).

test_waf_bypass(url, blocked_param, blocked_value, headers) — Test WAF evasion

Five bypass techniques: direct, duplicate_first, duplicate_last, encoded, array syntax. Detects if any technique passes WAF filtering (status 403/406/429 = blocked).

Payload Categories

Category Count Purpose
duplicate_param 3 Parameter precedence abuse
encoding_bypass 3 URL encoding / CRLF injection
array_syntax 3 PHP/framework array handling

Dependencies
