Library Options¶
All options that are available within the Wfuzz command line interface are available as library options:
CLI Option | Library Option |
---|---|
<URL> | url=”url” |
–recipe <filename> | recipe=[“filename”] |
–oF <filename> | save=”filename” |
-f filename,printer | printer=(“filename”, “printer”) |
–dry-run | dryrun=True |
-p addr | proxies=[(“ip”,”port”,”type”)] |
-t N | concurrent=N |
-s N | delay=0.0 |
-R depth | rleve=depth |
–follow | follow=True |
-Z | scanmode=True |
–req-delay N | req_delay=0 |
–conn-delay N | conn_delay=0.0 |
–no-cache | no_cache=True |
–script=<plugins> | script=”plugins” |
–script-args n1=v1,… | script_args={n1: v1} |
-m iterator | iterator=”iterator” |
-z payload | payloads=[(“name”,{default=”“,encoder=[“md5”]},slice=”“),] |
-V alltype | allvars=”alltype” |
-X method | method=”method” |
–hc/hl/hw/hh N[,N]+ | hc/hl/hw/hh=[N,N] |
–sc/sl/sw/sh N[,N]+ | sc/sl/sw/sh=[N,N] |
–ss/hs regex | ss/hs=”regex” |
–filter <filter> | filter=”filter exp” |
–prefilter <filter> | prefilter=”prefilter exp” |
-b cookie | cookie=[“cookie1=value1”,] |
-d postdata | postdata=”postdata” |
-H header | headers=[(“header1”, “value1”),] |
–basic/ntlm/digest auth | auth=(“basic”, “user:pass”) |
These options can be used in the main library interfaces: fuzz, payload or session indistinctly.
Fuzzing a URL¶
Fuzzing a URL with wfuzz library is very simple. Firstly, import the wfuzz module:
>>> import wfuzz
Now, let’s try to fuzz a web page to look for hidden content, such as directories. For this example, let’s use Acunetix’s testphp (http://testphp.vulnweb.com/):
>>> import wfuzz
>>> for r in wfuzz.fuzz(url="http://testphp.vulnweb.com/FUZZ", hc=[404], payloads=[("file",dict(fn="wordlist/general/common.txt"))]):
... print r
...
00060: C=301 7 L 12 W 184 Ch "admin"
00183: C=403 10 L 29 W 263 Ch "cgi-bin"
00429: C=301 7 L 12 W 184 Ch "images"
...
Now, we have a FuzzResult object called r. We can get all the information we need from this object.
FuzzSession object¶
A FuzzSession object has all the methods of the main wfuzz API.
The FuzzSession object allows you to persist certain parameters across fuzzing sessions:
>>> import wfuzz
>>> s = wfuzz.FuzzSession(url="http://testphp.vulnweb.com/FUZZ")
>>> for r in s.fuzz(hc=[404], payloads=[("file",dict(fn="wordlist/general/common.txt"))]):
... print r
...
00060: C=301 7 L 12 W 184 Ch "admin"
00183: C=403 10 L 29 W 263 Ch "cgi-bin"
...
FuzzSession can also be used as context manager:
>>> with wfuzz.FuzzSession(url="http://testphp.vulnweb.com/FUZZ", hc=[404], payloads=[("file",dict(fn="wordlist/general/common.txt"))]) as s:
... for r in s.fuzz():
... print r
...
00295: C=301 7 L 12 W 184 Ch "admin"
00418: C=403 10 L 29 W 263 Ch "cgi-bin"
Get payload¶
The get_payload function generates a Wfuzz payload from a Python iterable. It is a quick and flexible way of getting a payload programmatically without using Wfuzz payloads plugins.
Generating a new payload and start fuzzing is really simple:
>>> import wfuzz
>>> s = wfuzz.get_payload(range(5))
>>> for r in s.fuzz(url="http://testphp.vulnweb.com/FUZZ"):
... print r
...
00012: C=404 7 L 12 W 168 Ch "0"
00013: C=404 7 L 12 W 168 Ch "1"
00014: C=404 7 L 12 W 168 Ch "2"
00015: C=404 7 L 12 W 168 Ch "3"
00016: C=404 7 L 12 W 168 Ch "4"
The get_payloads method can be used when various payloads are needed:
>>> import wfuzz
>>> s = wfuzz.get_payloads([range(5), ["a","b"]])
>>> for r in s.fuzz(url="http://testphp.vulnweb.com/FUZZ/FUZ2Z"):
... print r
...
00028: C=404 7 L 12 W 168 Ch "4 - b"
00027: C=404 7 L 12 W 168 Ch "4 - a"
00024: C=404 7 L 12 W 168 Ch "2 - b"
00026: C=404 7 L 12 W 168 Ch "3 - b"
00025: C=404 7 L 12 W 168 Ch "3 - a"
00022: C=404 7 L 12 W 168 Ch "1 - b"
00021: C=404 7 L 12 W 168 Ch "1 - a"
00020: C=404 7 L 12 W 168 Ch "0 - b"
00023: C=404 7 L 12 W 168 Ch "2 - a"
00019: C=404 7 L 12 W 168 Ch "0 - a"
Get session¶
The get_session function generates a Wfuzz session object from the specified command line. It is a quick way of getting a payload programmatically from a string representing CLI options:
$ python
>>> import wfuzz
>>> s = wfuzz.get_session("-z range,0-10 http://testphp.vulnweb.com/FUZZ")
>>> for r in s.fuzz():
... print r
...
00002: C=404 7 L 12 W 168 Ch "1"
00011: C=404 7 L 12 W 168 Ch "10"
00008: C=404 7 L 12 W 168 Ch "7"
00001: C=404 7 L 12 W 168 Ch "0"
00003: C=404 7 L 12 W 168 Ch "2"
00004: C=404 7 L 12 W 168 Ch "3"
00005: C=404 7 L 12 W 168 Ch "4"
00006: C=404 7 L 12 W 168 Ch "5"
00007: C=404 7 L 12 W 168 Ch "6"
00009: C=404 7 L 12 W 168 Ch "8"
00010: C=404 7 L 12 W 168 Ch "9"
Interacting with the results¶
Once a Wfuzz result is available the grammar defined in the filter language can be used to work with the results’ values. For example:
$ python
>>> import wfuzz
>>> with wfuzz.get_session("-z list --zD test -u http://testphp.vulnweb.com/userinfo.php -d uname=FUZZ&pass=FUZZ") as s:
... for r in s.fuzz():
... print(r.history.cookies.response)
... print(r.history.params.all)
... print(r.history.params.post)
... print(r.history.params.post.uname)
... print(r.history.params.post['pass'])
{'login': 'test%2Ftest'}
{'uname': 'test', 'pass': 'test'}
{'uname': 'test', 'pass': 'test'}
test
test
>>>
The result object has also a method to evaluate a language expression:
>> print(r.eval("r.cookies.response"))
login=test%2Ftest
