Fuzzing with Manual Control

The Fuzzer tool extends manual testing by automating payload insertion while maintaining human control. Right-click any request parameter and select "Fuzz" to open the Fuzzer dialog. Configure payload sources from built-in lists or custom files. This semi-automated approach tests specific parameters thoroughly while avoiding the noise of full automated scanning.

Payload selection requires understanding of vulnerability types and application context. Use SQL injection payloads for database-driven parameters, XSS payloads for reflected output, and command injection strings for system interaction points. ZAP includes categorized payload lists, but custom payloads often prove more effective for specific applications.

Results analysis from fuzzing requires human intelligence to identify successful attacks. Look for response changes indicating successful injection: error messages for SQL injection, reflected payloads for XSS, or time delays for blind injection. Sort results by response size, status code, or time to identify anomalies. The combination of automated fuzzing with manual analysis efficiently identifies vulnerabilities.
