Uno strumento per FUZZare applicazioni web ovunque.

Wfuzz è stato creato per facilitare il compito nelle valutazioni delle applicazioni web ed è basato su un concetto semplice: sostituisce qualsiasi riferimento alla parola chiave FUZZ con il valore di un determinato payload.

Installazione

Installato in Kali

Github: https://github.com/xmendez/wfuzz

pip install wfuzz

Opzioni di filtraggio

--hs/ss "regex" #Hide/Show
#Simple example, match a string: "Invalid username"
#Regex example: "Invalid *"

--hc/sc CODE #Hide/Show by code in response
--hl/sl NUM #Hide/Show by number of lines in response
--hw/sw NUM #Hide/Show by number of words in response
--hh/sh NUM #Hide/Show by number of chars in response
--hc/sc NUM #Hide/Show by response code

Opzioni di output

wfuzz -e printers #Prints the available output formats
-f /tmp/output,csv #Saves the output in that location in csv format

Opzioni di codifica

wfuzz -e encoders #Prints the available encoders
#Examples: urlencode, md5, base64, hexlify, uri_hex, doble urlencode

Per utilizzare un encoder, devi indicarlo nell'opzione "-w" o "-z".

Esempi:

-z file,/path/to/file,md5 #Will use a list inside the file, and will transform each value into its md5 hash before sending it
-w /path/to/file,base64 #Will use a list, and transform to base64
-z list,each-element-here,hexlify #Inline list and to hex before sending values
