API Reference: Web Application Penetration Test Agent

Overview

Performs automated web application security testing: technology fingerprinting, security header checks, HTTP method testing, CORS misconfiguration detection, basic SQL injection, and reflected XSS testing.

Dependencies

Package Version Purpose
requests >= 2.28 HTTP client for all web tests

External Tools (Optional)

Tool Purpose
ffuf Directory and file brute-forcing

Core Functions

fingerprint_technology(target_url)

Identifies server, framework, and language from headers and cookie names.

  • Returns: dict with server and technologies list

check_security_headers(target_url)

Checks HSTS, CSP, X-Content-Type-Options, X-Frame-Options, X-XSS-Protection, Referrer-Policy, Permissions-Policy.

  • Returns: dict[str, dict] - header to presence/value mapping

test_http_methods(target_url)

Tests for dangerous HTTP methods (PUT, DELETE, TRACE, CONNECT).

  • Returns: list[dict] - allowed dangerous methods with risk levels

test_cors_config(target_url)

Tests CORS with evil origins, null origin, and subdomain spoofing.

  • Returns: list[dict] - reflected origins with credential risks

run_directory_bruteforce(target_url, wordlist)

Subprocess wrapper for ffuf directory enumeration.

  • Default wordlist: /usr/share/seclists/Discovery/Web-Content/common.txt

test_sql_injection_basic(target_url, params)

Tests URL parameters with SQL injection payloads and checks for database error strings.

  • Risk: CRITICAL when SQL error patterns detected

test_xss_basic(target_url, params)

Tests for reflected XSS by checking if payloads appear unescaped in response body.

  • Risk: HIGH when payload is reflected

run_assessment(target_url, test_params)

Full assessment pipeline with summary statistics.
