aibot88 Input Validation Scanner
Overview
Scan application source code for missing or insufficient input validation that could lead to injection attacks (SQL, XSS, command injection), buffer overflows, and path traversal vulnerabilities. Analyzes how user-provided data flows from HTTP parameters, form fields, and API inputs through the application to identify locations where sanitization or validation is absent.
How It Works
- Initiate Scan: The user requests an input validation scan, triggering the skill.
- Code Analysis: The skill uses the input-validation-scanner plugin to analyze the specified codebase or file.
- Vulnerability Identification: The plugin identifies instances where input validation may be missing or insufficient.
- Report Generation: The skill presents a report highlighting potential vulnerabilities and their locations in the code.
When to Use This Skill
This skill activates when you need to:
- Audit a codebase for input validation vulnerabilities.
- Review newly written code for potential XSS or SQL injection flaws.
- Harden an application against common web security exploits.
- Ensure compliance with security best practices related to input handling.
Examples
Example 1: Identifying XSS Vulnerabilities
User request: "Scan the user profile module for potential XSS vulnerabilities."
The skill will:
- Activate the input-validation-scanner plugin on the specified module.
- Generate a report highlighting areas where user input is directly rendered without proper sanitization, indicating potential XSS vulnerabilities.
Example 2: Checking for SQL Injection Risks
User request: "Check the database access layer for potential SQL injection risks."
The skill will:
- Use the input-validation-scanner plugin to examine the database access code.
- Identify instances where user input is used directly in SQL queries without proper parameterization or escaping, indicating potential SQL injection vulnerabilities.
Best Practices
- Regular Scanning: Integrate input validation scanning into your regular development workflow.
- Contextual Analysis: Always review the identified vulnerabilities in context to determine their actual impact and severity.
- Comprehensive Validation: Ensure that all user-supplied data is validated, including data from forms, APIs, and external sources.
Integration
This skill can be used in conjunction with other security-related skills to provide a more comprehensive security assessment. For example, it can be combined with a static analysis skill to identify other types of vulnerabilities or with a dependency scanning skill to identify vulnerable third-party libraries.
