This tool performs various checks via headers, path normalization, verbs, etc. to attempt to bypass ACL’s or URL validation.
It will output the response codes and length for each request, in a nicely organized, color coded way so things are reaable.
I implemented a “Smart Filter” that lets you mute responses that look the same after a certain number of times.
You can now feed it raw HTTP requests that you save to a file from Burp.
usage: bypassfuzzer.py -h
Simply paste the request into a file and run the script!
cookies
& headers
from the request.python3 bypassfuzzer.py -r request.txt
python3 bypassfuzzer.py -u http://example.com/test1/test2/test3/forbidden.html
--cookies "cookie1=blah"
-c "cookie1=blah; cookie2=blah"
Specify a method/verb and body data to send
bypassfuzzer.py -u https://example.com/forbidden -m POST -d "param1=blah¶m2=blah2"
bypassfuzzer.py -u https://example.com/forbidden -m PUT -d "param1=blah¶m2=blah2"
Specify custom headers to use with every request Maybe you need to add some kind of auth header like Authorization: bearer <token>
Specify -H "header: value"
for each additional header you’d like to add:
bypassfuzzer.py -u https://example.com/forbidden -H "Some-Header: blah" -H "Authorization: Bearer 1234567"
Based on response code and length. If it sees a response 8 times or more it will automatically mute it.
Repeats are changeable in the code until I add an option to specify it in flag
NOTE: Can’t be used simultaneously with -hc
or -hl
(yet)
# toggle smart filter on
bypassfuzzer.py -u https://example.com/forbidden --smart
Useful if you wanna proxy through Burp
bypassfuzzer.py -u https://example.com/forbidden --proxy http://127.0.0.1:8080
Skip sending header payloads or url payloads
# skip sending headers payloads
bypassfuzzer.py -u https://example.com/forbidden -sh
bypassfuzzer.py -u https://example.com/forbidden --skip-headers
# Skip sending path normailization payloads
bypassfuzzer.py -u https://example.com/forbidden -su
bypassfuzzer.py -u https://example.com/forbidden --skip-urls
Provide comma delimited lists without spaces. Examples:
# Hide response codes
bypassfuzzer.py -u https://example.com/forbidden -hc 403,404,400
# Hide response lengths of 638
bypassfuzzer.py -u https://example.com/forbidden -hl 638
