name	detecting-injection
description	Detects various injection vulnerabilities including SQL injection, LDAP injection, XPath injection, and code injection. Use when analyzing database queries, dynamic code generation, or investigating injection attacks.

Injection Detection

Detection Workflow

1. Identify injection points: Find database query construction, locate dynamic code generation, identify template rendering, map all user input usage
2. Trace user input: Use xrefs_to to trace data, follow input to injection points, check for sanitization, identify bypass opportunities
3. Check sanitization: Verify input validation, check for parameterized queries, assess escaping mechanisms, look for whitelist/blacklist usage
4. Assess exploitability: Can attacker inject malicious content? What's the impact of injection? Are there mitigations?

Key Patterns

• SQL injection: string concatenation in SQL queries, dynamic query construction, missing parameterized queries, stored procedure injection
• LDAP injection: user input in LDAP filters, unsafe LDAP query construction, special character handling issues, DN manipulation
• XPath injection: user input in XPath expressions, unsafe XPath construction, XML entity injection, blind XPath injection
• Code injection: eval() or similar dynamic code execution, template injection, server-side template injection (SSTI), deserialization attacks

Output Format

Report with: id, type, subtype, severity, confidence, location, vulnerability, injection_point (function, address, query), source, injection_technique, exploitable, attack_scenario, payload_example, mitigation.

Severity Guidelines

• CRITICAL: SQL injection with full database access
• HIGH: Other injection with data access
• MEDIUM: Limited injection impact
• LOW: Potential injection with minor impact
