Security & Vulnerability Testing Suite

To ensure your web applications are resilient against common security threats, hexbuffer includes specialized, context-aware testing modules for SQL Injection (SQLi) and Cross-Site Scripting (XSS) payload generation.

SQL Injection & Boundary Tester

The SQL Injection Tester helps verify whether user input fields properly sanitize database query parameters before executing SQL queries.

Key Capabilities

• Vector Categories: Includes error-based, boolean-based blind, time-based blind, and UNION query payload vectors.
• Automated Validation: Analyzes server responses for database error patterns (MySQL, PostgreSQL, SQLite, MSSQL, Oracle).
• Safe Boundary Checking: Designed to identify input validation weaknesses without causing database corruption or data loss.

XSS Payload Generator & Encoder

The XSS Generator crafts context-aware payload vectors to test whether web applications adequately escape user-supplied input rendered in HTML, attribute contexts, JavaScript blocks, or URI query strings.

Key Capabilities

• Context Awareness: Generates tailored payloads based on where input is reflected (e.g., inside <div> tags, <input value="..."> attributes, or <script> blocks).
• Nested Encoders: Integrates Base64, URL encoding, HTML entity encoding, and Hex escaping to test bypass mechanisms against over-filtering.
• DOM-Based XSS Inspection: Scans client-side JavaScript execution sinks to flag unescaped DOM assignments (innerHTML, document.write, eval).

Remediation & Best Practices

Testing with hexbuffer provides clear actionable feedback for engineering teams:

[!IMPORTANT] Use Parameterized Queries: To prevent SQL Injection, always use prepared statements or parameterized ORM queries in your backend codebase.

[!TIP] Contextual HTML Escaping: To prevent XSS, use framework-level auto-escaping (such as React or modern templating engines) and implement a robust Content Security Policy (CSP).
