SQL Injection Testing

Purpose

Execute comprehensive SQL injection vulnerability assessments on web applications to identify database security flaws, demonstrate exploitation techniques, and validate input sanitization mechanisms. This skill enables systematic detection and exploitation of SQL injection vulnerabilities across in-band, blind, and out-of-band attack vectors to assess application security posture.

Inputs / Prerequisites

Required Access

• Target web application URL with injectable parameters
• Burp Suite or equivalent proxy tool for request manipulation
• SQLMap installation for automated exploitation
• Browser with developer tools enabled

Technical Requirements

• Understanding of SQL query syntax (MySQL, MSSQL, PostgreSQL, Oracle)
• Knowledge of HTTP request/response cycle
• Familiarity with database schemas and structures
• Write permissions for testing reports

Legal Prerequisites

• Written authorization for penetration testing
• Defined scope including target URLs and parameters
• Emergency contact procedures established
• Data handling agreements in place

Outputs / Deliverables

Primary Outputs

• SQL injection vulnerability report with severity ratings
• Extracted database schemas and table structures
• Authentication bypass proof-of-concept demonstrations
• Remediation recommendations with code examples

Evidence Artifacts

• Screenshots of successful injections
• HTTP request/response logs
• Database dumps (sanitized)
• Payload documentation

Core Workflow

Phase 1: Detection and Reconnaissance

Identify Injectable Parameters

Locate user-controlled input fields that interact with database queries:

# Common injection points
- URL parameters: ?id=1, ?user=admin, ?category=books
- Form fields: username, password, search, comments
- Cookie values: session_id, user_preference
- HTTP headers: User-Agent, Referer, X-Forwarded-For

Test for Basic Vulnerability Indicators

Insert special characters to trigger error responses:

-- Single quote test
'

-- Double quote test
"

-- Comment sequences
--
#
/**/

-- Semicolon for query stacking
;

-- Parentheses
)
