description	Injection vulnerability testing - SQL, NoSQL, OS Command, SSTI, XXE, and LDAP/XPath injection techniques.

Injection

Test for injection vulnerabilities across all input vectors. Covers SQL, NoSQL, Command, SSTI, XXE, and LDAP injection.

Techniques

Type	Key Vectors
SQL Injection	In-band (union, error), Blind (boolean, time), Out-of-band
NoSQL Injection	Operator injection, JavaScript injection, aggregation pipeline
Command Injection	OS command separators, blind techniques, out-of-band
SSTI	Template engine detection, sandbox escape, RCE chains
XXE	Entity expansion, SSRF via XXE, blind XXE, parameter entities
LDAP/XPath	Filter manipulation, authentication bypass

Workflow

1. Identify injection points (parameters, headers, cookies, JSON fields)
2. Detect injection type with minimal probes
3. Exploit with context-appropriate payloads
4. Escalate (data extraction, RCE, file read)
5. Capture evidence and write PoC
