wfuzz

HTTP fuzzing tool built around payload injection via FUZZ tokens.

Quick Start

pip install wfuzz

# Directory fuzzing
wfuzz -c -w wordlist.txt --hc 404 https://target/FUZZ

# Parameter fuzzing
wfuzz -c -w payloads.txt "https://target/search?q=FUZZ"

Operator Flow

1. Establish baseline response shape (status/lines/words/chars).
2. Run discovery pass with hide filters (--hc/--hl/--hw/--hh).
3. Switch to targeted payloads (params, headers, auth, verbs).
4. Use filter language and plugin outputs for second-pass triage.
5. Save/reuse sessions for reproducible follow-up tests.

Common Uses

• Path/file discovery.
• Query/form/header fuzzing.
• Auth and session edge-case probing.
• Semi-automatic testing around captured requests.

High-Value Features

• Baseline token (FUZZ{baseline} + BBB) for differential filtering.
• Multi-payload iterators (product, zip, chain) for combination testing.
• Advanced filter grammar (--filter, --prefilter, --slice).
• Scan plugins (--script) for parse/discovery-assisted workflows.
• Reuse prior sessions (wfuzzp, Burp state/log payloads) for contextual fuzzing.

Practical Tricks

• Use -Z scan mode when enumerating unstable hostnames/services; then filter XXX errors explicitly.
• When brute forcing behind proxies, tune --conn-delay and --req-delay to avoid false noise.
• Use --field / --efield to emit pipeline-friendly output into other tools.

Common Pitfalls

• Running large dictionaries without baseline filters (noise flood).
• Ignoring soft-404 patterns and relying only on status code.
• Fuzzing all components at once instead of phased request decomposition.

Notes

• In this repository, ffuf is often the faster default for bulk enumeration.
• Use wfuzz when you need its plugin/modular style and FUZZ-placement flexibility.
