Changelog

Upcoming

Features

  • Remove six compatibility module
  • Remove Python 2 compatibility code.
  • Remove specifying object inheritance in classes
  • Added Web UI listening on specific IP address
  • Added Python 3.11 compatibility.

Fixes

  • Specified encoding on file write rather than assuming default encoding
  • Changed type of default_value from string to bytes for FromFile.
  • s_update primitive was out of date.
  • The minimum supported Python version is now 3.7.

v0.4.1

Features

  • Added support for fuzzing NETCONF servers with the NETCONFConnection class.
  • Add support and tests for Python 3.10.
  • Added Session arg db_filename to modify the location of the log database.

Fixes

  • Fixed check for when to enable the web app.
  • Documented the possibility to disable the web app.
  • Correctly initialize all children of a request which inherits from FuzzableBlock.
  • Added type checking for arguments of Bytes primitive to prevent incorrect use.
  • Fixed TypeError in s_binary initialization.
  • Remove redundant unicode strings.

v0.4.0

Features

  • Fuzzing CLI -- Use main_helper() to use boofuzz's generic fuzzing CLI with your script.
  • 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.
  • Added simple custom checksum and example usage.
  • Added Simple primitive that uses only the specified values for fuzzing.
  • Added Float primitive with support for IEEE 754 encoding.
  • Added an example for s_float/Float usage.

Fixes

  • Clarified documentation of custom checksum function for Checksum primitive.
  • String and RandomData primitives now use a local and independent instance of random.
  • The minimum supported Python version is now 3.6.
  • Fixed two memory leaks in the fuzz logger.

v0.3.0

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.

  • 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.

  • 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.

Features

  • Web UI
    • Test case numbers are now clickable and link to test case detail view.

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.

Features

  • Added several command injection strings from fuzzdb.
  • Blocks can now be created and nested using with s_block("my-block"):

Fixes

  • Fixed pydot import error message

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.

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

0.0.5

    • This makes it way easier to use. Everything can be used like boofuzz.MyClass instead of boofuzz.my_file.MyClass.
  • Added EzOutletReset class to support restarting devices using an ezOutlet EZ-11b.

Backwards-incompatible

  • Target now only takes an ITargetConnection. This separates responsibilities and makes our code more flexible with different kinds of connections.

Fixes

  • Bugs fixed:
    • helpers.udp_checksum was failing with oversized messages.
    • Missing install requirements.
    • Grammar and spelling.
    • setup.py was previously installing around five mostly unwanted packages. Fixed.
    • Removed deprecated unit tests.
    • Removed overly broad exception handling in Session.
    • Checksum.render() for UDP was not handling dependencies properly.

Back-end Improvements

This section took the most work. It has the least visible impact, but all of the refactors enable new features, fixes, and unit tests.

  • Primitives and Blocks:
    • Created IFuzzable which properly defines interface for Block, Request, and all BasePrimitive classes.
    • Made effectively private members actually private.
    • Eliminated exhaust() function. It was used only once and was primarily a convoluted break statement. Now it's gone. :)
    • Split all block and primitive classes into separate files.
  • Many Unit tests added.

Other

  • Continuous integration with Travis is running!
  • Doc organization improvements.
  • Can now install with extras [dev]

  • Better recording of test data.
    • Records all sent and received data
    • Records errors in human-readable format, in same place as sent/received data.
  • Improved functionality in checksum blocks.
  • Self-referential size and checksum blocks now work.
  • post_send callbacks can now check replies and log failures.
  • Far fewer bugs.
  • Numerous refactors within framework code.
