Boofuzz is a fork of and the successor to the venerable Sulley fuzzing framework. Besides numerous bug fixes, boofuzz aims for extensibility. The goal: fuzz everything.

Why?

Sulley has been the preeminent open source fuzzer for some time, but has fallen out of maintenance.

Features

Like Sulley, boofuzz incorporates all the critical elements of a fuzzer:

Easy and quick data generation.
Instrumentation – AKA failure detection.
Target reset after failure.
Recording of test data.

Unlike Sulley, boofuzz also features:

Online documentation.
Support for arbitrary communications mediums.
Built-in support for serial fuzzing, ethernet- and IP-layer, UDP broadcast.
Better recording of test data -- consistent, thorough, clear.
Test result CSV export.
Extensible instrumentation/failure detection.
Much easier install experience!
Far fewer bugs.

Sulley is affectionately named after the giant teal and purple creature from Monsters Inc. due to his fuzziness. Boofuzz is likewise named after the only creature known to have scared Sulley himself: Boo!

Boo from Monsters Inc

Improved & Reworked Monitor infrastructure
So, this is going to be a big one, and while unfinished, I'd like to invite everyone to read my changes.

Breaking changes in this PR:

target.netmon_options and target.procmon_options are gone. Instead, you can supply callbacks that get called when a monitor gets alive; set your options there. However, I am currently debating whether I should move the callback logic into the monitors themselves, the logic for that shouldn't be in target at all.

data dump format: procmon_results is now monitor_results, netmon_results is now monitor_data. monitor_results are collected for all testcases where one monitor detected a failure where as supplement data is collected for every testcase (like netmon was).

ToDo

[x] reuse_target_connection seems to be broken for any case that doesn't use a custom callback method for restarting; however I think this should be fixed in another PR. Open another Issue maybe?

[x] Test/Fix Webinterface (I'll do a quick job here and probably iron over it in a future PR)

[x] Fix/Add Tests

[x] Write docs

[x] Move boofuzz/pedrpc.py to boofuzz/monitors/pedrpc.py (?)

[x] Move boofuzz/instrumentation.py to boofuzz/monitors/external.py, let it implement IMonitor, rename to ExternalMonitor

[x] Add hook monitor

[x] move all the callback functions into the monitor infrastructure - I think we should keep the session arguments, but internally use the monitor infrastructure to simplify the implementation in the Session class.

General Every breaking change throws an exception with reasoning. Every non-breaking change emits a warning (as long as I did not miss anything). We can debate whether we want to keep the NotImplementedExceptions; I would argue that we should keep them and remove them when we remove the rest of the to-be-deprecated interfaces.

Fixes #380

Fix broken TLS

Fuzzing a SSL/TLS enabled server did not work anymore. I got this error:

Traceback (most recent call last):

TypeError: unbound method wrap_socket() must be called with SSLContext instance as first argument (got _socketobject instance instead)

The solution was simple: Use ssl.wrap_socket instead of ssl.SSLContext.wrap_socket.

In order to reproduce, please use this script:

#!/usr/bin/env python2
from boofuzz import *

session = Session(
    target=Target(
        connection=SocketConnection(
            host="127.0.0.1",
            port=12345,
            proto='ssl', 
            ),
    ),
)
s_initialize("A")
s_byte(0x41)
session.connect(session.root, s_get("A"))
session.fuzz()

and run it against a test server with

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
openssl s_server -accept 12345 -key key.pem -cert cert.pem

Added python3 compatibility

This pull request is for adding compatibility for python 3 without losing compatibility with python 2. In many cases I am utilizing the "six" library.

For future work, but as a separate issue, I think we should work on making all data stored as a "six.binary_type" to guarantee compatibility between python versions and to avoid needing to worry about the encoding of the string object.

Some additional issue I believe we should open would be to update the contribution guide, and to add more testing to the framework

Added curses logger class to provide a console GUI

First attempt to add a console GUI. Use session option console_gui to enable. If constructed with default arguments keep_web_open is redundant, so it's being disabled. There is still a bug where the screen dimensions aren't correctly read on the first startup, just resize the window to fix this. Resizing the window smaller than 130x40 (WxH) will output a black screen to avoid curses errors.

I'd like to show the paused status too, but I couldn't find a way to pass the value to the logger class without adding another function to all logger classes as I already did with the window resize function. This is something for another time though.

The SIGWINCH handler is necessary as the curses default handler interrupts sleeps, which might result in errors when the minimum sleep time between cases is suddenly shortened. With the custom signal handler the sleep time is restarted when a resize event is caught. That again might result in longer sleep times than expected, but in my opinion this is the evil. To prevent this we'd have to write a custom sleep function.

I haven't tested this under Windows at all, it would be nice if someone else could. windows-curses is definitely needed.

Suggestions, especially about the design, are welcome.

HTTP server with authentication

Hi,

I'm searching to fuzz my HTTP server and its API, this server is protected by an authentication phase. Authentication process is by HTTP request containing username and password. Server response will contain an authenticated token the client will need for all subsequent requests (integrated in "Authorization" header field).

In order to fuzz the API, Boofuzz has to authenticate itself to the server. How can I do that ?

Split SocketConnection into subclasses
Packet sockets may be bound to an interface, restricting the recieved packets to come from a specific interface. Additionally, recieving on raw sockets can be filtered by protocol (like it's done already for raw-l3). This commit makes this functionality available to the user.

TODO:

[x] Update documentation consistently

[x] Update changelog

[ ] Write unit-test for raw socket receiving (optimal but would be really nice to have)

[x] Update examples folder (optimal, could be done in another PR)

OSError: [Errno 98] Address already in use

I use SocketConnection with tcp protocol.

When I run a bunch of tests, sometimes (for me usually after between 15 000 - 30 000 test cases) I got the following error:

Traceback (most recent call last):

It happens on both Windows and WSL and different versions of Python. No other application is connecting to the target port. Any ideas?

Update block and primitive documentation

I noticed that parts of the new protocol definition documentation is incomplete, so I completely reworked that part. The static protocol definition documentation remains mostly the same, to prevent breaking changes.

There's one thing I'm uncertain about: Should each primitives docstring and signature contain the name and fuzzable parameter? Technically this is not needed because we pass kwargs down to Fuzzable, however I think it would make it more clear for the user which parameter a primitive/block can take.

So on top of this change I'd suggest adding the fuzzable parameter after name, just like we have it on most static definitions.

Documentation Template

Hey,

so I know this was discussed recently in #347, but I have a few more comments on the situation. In particular, I have one major issue with the current theme - the menu sidebar is completely gone if my browser only occupates 1/2 of my 1920x1080 screen.

To access the menu, I have to scroll all the way down. In my opinon, this sucks from an UX perspective. How easy is it for us to modify the theme? If we could reasonably easy modify the template, I'd propose an off-canvas approach. If not, I would advocate for discussing another theme again.

add primitive s_bytes: fuzz arbitrary binary data
This was requested in issue #144.

The code is kind of cumbersome because of the cumbersome API of BasePrimitive. However, I've tested it on Python 2 and Python 3 and it seems to work.

The fuzzing strategy for an arbitrary length, binary string is:

replace binary value with list of static binary strings

replace each 1 byte block in original value with list of static 1byte strings

replace each 2 byte block in original value with list of static 2byte strings

replace each 4 byte block in original value with list of static 4byte strings

I've compiled the list of interesting strings based on the wikipedia list of magic debug values and some others based on my gut feeling. Please feel free to change them.

Minimal sample to test it:

#!/usr/bin/env python from boofuzz import * session = Session( target=Target( connection=SocketConnection( host="127.0.0.1", port=12345, proto='tcp', server=True ),),) s_initialize("A") s_bytes(b"0000000000000000000") session.connect(session.root, s_get("A")) session.fuzz()

and run while [ True ]; do nc 127.0.0.1 12345 | hexdump -C; sleep 0.1; done in another terminal.

http with multi-connect :session.connect(s.get"xxx")
Proposal

In some blogs, session.connect for FTP is like:

session.connect(s_get("user")) session.connect(s_get("user"), s_get("pass")) session.connect(s_get("pass"), s_get("stor")) session.connect(s_get("pass"), s_get("retr"))

So, maybe it is useful for FTP protocol, if i want to fuzz more after login; However, with HTTP request，how could I connect 2 or 3 request after I login successfully？

"Aligned" definition function's implementation is incorrect,modify the encode method

Proposal

def encode(self, value, mutation_context): child_data = self.get_child_data(mutation_context=mutation_context) "Aligned" can't get child data using 'get_child_data' because of it has no stack menber.I suggest taking a approach like "Size" function to get the data associated with the request parameter.

Use-Case

My modified code is as follows: def encode(self, value, mutation_context): if self.request is not None and self.block_name is not None: target_block = self.request.resolve_name(self.context_path,self.block_name) child_data = target_block.render(mutation_context=mutation_context) padding_length = self._modulus - (len(child_data) % self._modulus) a, b = divmod(padding_length, len(self._pattern)) # remove return child_data return self._pattern * a + self._pattern[:b] else: return

Session.fuzz_by_name is deprecated in favor of Session.fuzz(name=name).
Report

Session.fuzz_by_name unconditionally emits the following warning:

Session.fuzz_by_name is deprecated in favor of Session.fuzz(name=name).

However, if you look at the source code of Session.fuzz(name="something"), you'll find this: https://github.com/jtpereyda/boofuzz/blob/5ee41f878b785d16c8bd9bbea8dd4f4c37525e1b/boofuzz/sessions.py#L1280-L1291

So the "correct" way to call this will trigger the warning.

Expected behavior

No warning if the correct method is used.

Actual behavior

Warning is displayed regardless of method used.

Steps to reproduce the problem

use session.fuzz(name="anything")

Combinatorial fuzzing -- now fuzzes multiple mutations at once by default.

Test cases can now be specified and re-run by name.

Implemented visual request-graph rendering functions for Session.

Added to web UIL: runtime, exec speed, current test case name.

Source code(tar.gz)
Source code(zip)
v0.3.0(Feb 28, 2021)
This release brings some huge memory optimizations as we are now using iterators to generate the test case data. Boofuzz will no longer munch Gigabytes of RAM when fuzzing with large protocol definitions! Also check out the new object orientated method for defining protocols here.

Features

Memory optimization: Efficient mutation generation and smarter string reuse -- decrease memory consumption by orders of magnitude.

Aligned block: Aligns content length to multiple of certain number of bytes.

Relative names: Name references for Checksum, Size, etc. now resolve absolute and relative names. Block and primitive names no longer need to be globally unique within a message, they only need to be locally unique within a block.

Passing data between messages: Callbacks now have a TestCaseContext object to which one can save data to be used later in the test case. TestCaseSessionReference can be passed as a default value in a protocol definition. The name it references must have been saved by the time that message in the protocol is reached.

Fuzzable rewrite: Simpler definitions for new fuzz primitives. See static.py for an example of a very simple primitive.

Protocol definition: Protocols can now be defined with an object oriented rather than static approach.

Independent mutation and encoding steps: Will enable multiple mutations and code coverage feedback.

Procmon: Additional debug steps. Partial backwards compatibility for old interface.

ProcessMonitorLocal allows running procmon as part of fuzzer process.

Network monitor: improved network interface discovery (Linux support).

Added support for fuzzing Unix sockets with the UnixSocketConnection class.

Added metadata to ProtocolSession to support callbacks -- current_message, previous_message.

All primitive arguments are now optional keyword arguments.

Fixes

Various web interface fixes.

Various refactors and simplifications.

Fewer duplicates from Group primitives.

Network monitor: fixed data_bytes calculation and PcapThread synchronization.

Fixed a crash when using the network monitor.

Session can now be "quiet" by passing an empty list of loggers.

Process Monitor: fixed Thread.isAlive for Python 3.9 compatibility.

Correctly truncate values of the string primitive when max_len or size is set.

The string primitive will no longer generate duplicates when max_len or size is set.

Greatly improved string to bytes conversion speed.

Rewrote and split the SocketConnection class into individual classes per socket type.

SocketConnection is now deprecated. Use the classes derived from BaseSocketConnection instead.

Added support for receiving on raw Layer 2 and Layer 3 connections.

Layer 2 and Layer 3 connections may now use arbitrary payload / MTU sizes.

Moved connection related modules into new connections submodule.

Added the ability to repeat sending of packages within a given time or count.

Added optional timeout and threshold to quit infinite connection retries.

Reworked Monitors, consolidated interface. Breaking change: session no longer has netmon_options and procmon_options.

SessionInfo has had attributes renamed; procmon_results and netmon_results are deprecated and now aliases for monitor_results and monitor_data respectively.

New BoofuzzFailure exception type allows callback methods to signal a failure that should halt the current test case.

Added capture_output option to process monitor to capture target process stderr/stdout .

Added post-start-target callbacks (called every time a target is started or restarted).

Added method to gracefully stop PED-RPC Server.

Added new boofuzz logo and favicon to docs and webinterface.

Added FileConnection to dump messages to files.

Removed deprecated session arguments fuzz_data_logger, log_level, logfile, logfile_level and log().

Fixes

Fixed size of s_size block when output is ascii.

Fixed issue with tornado on Python 3.8 and Windows.

Fixed various potential type errors.

Renamed requests folder to request_definitions because it shadowed the name of the requests python module.

Examples are up to date with current Boofuzz version.

Modified timings on serial_connection unit tests to improve test reliability.

Refactored old unit-tests.

Fixed network monitor compatibility with Python 3.

Minor console GUI optimizations.

Fixed crash_threshold_element handling if blocks are used.

Fixed many bugs in which a failure would not stop the test case evaluation.

Fixed setting socket timeout options on Windows.

If all sockets are exhausted, repeatedly try fuzzing for 4 minutes before failing.

Fixed CSV logger send and receive data decoding.

Handle SSL-related exception. Added ignore_connection_ssl_errors session attribute that can be set to True to ignore SSL-related error on a test case.

Fixed s_from_file decoding in Python 2 (the encoding parameter is now depreciated).

Updated documentation of s_checksum. It is possible to use a custom algorithm with this block.

v0.0.8(May 7, 2017)
0.0.8

Features

Console output - now with colors!

process_monitor_unix.py: added option to move coredumps for later analysis.

The process monitor (procmon) now tracks processes by PID by default rather than searching by name. Therefore, stop_commands and proc_name are no longer required.

SIGINT (AKA Ctrl+C) now works to close both boofuzz and process_monitor.py (usually).

Made Unix procmon more compatible with Windows.

Improved procmon debugger error handling, e.g., when running 64-bit apps.

Windows procmon now runs even if pydbg fails.

Added --help parameter to process monitor.

Target class now takes procmon and procmon_options in constructor.

Added example fuzz scripts.

Fixes

SIGINT (AKA Ctrl+C) now works to close both boofuzz and process_monitor.py (usually).

Fixed: The pedrpc module was not being properly included in imports.

Made process_monitor.py --crash_bin optional (as documented).

Improved procmon behavior when certain parameters aren't given.

Improved procmon error handling.

Fixed a bug in which the procmon would not properly restart a target that had failed without crashing.

v0.0.6(Nov 7, 2016)
0.0.6

Features

Added Request.original_value() function to render the request as if it were not fuzzed. This will help enable reuse of a fuzz definition to generate valid requests.

SocketConnection can now send and receive UDP broadcast packets using the udp_broadcast constructor parameter.

Target.recv() now logs an entry before receiving data, in order to help debug receiving issues.

Fixes

Maximum UDP payload value was incorrect, causing crashes for tests running over UDP. It now works on some systems, but the maximum value may be too high for systems that set it lower than the maximum possible value, 65507.

SocketConnection class now handles more send and receive errors: ECONNABORTED, ECONNRESET, ENETRESET, and ETIMEDOUT.

Fixed setup.py to not include superfluous packages.

Development

Added two exceptions: BoofuzzTargetConnectionReset and BoofuzzTargetConnectionAborted.

These two exceptions are handled in sessions.py and may be thrown by any ITargetConnection implementation.

Source code(tar.gz)
Source code(zip)
v0.0.5(Sep 5, 2016)
0.0.5

Fixes

Boofuzz now properly reports crashes detected by the process monitor. It was calling log_info instead of log_fail.

Boofuzz will no longer crash, but will rather give a helpful error message, if the target refuses socket connections.

Add utils/crash_binning.py to boofuzz/utils, avoiding import errors.

Fix procmon argument processing bug.

Fix typos in INSTALL.rst.
