Injection Detection

Detection Workflow

Identify injection points: Find database query construction, locate dynamic code generation, identify template rendering, map all user input usage
Trace user input: Use xrefs_to to trace data, follow input to injection points, check for sanitization, identify bypass opportunities
Check sanitization: Verify input validation, check for parameterized queries, assess escaping mechanisms, look for whitelist/blacklist usage
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
