dfuzz - automated daemon fuzzer

Project description

dfuzz - automatic daemon configuration fuzzer. Rather than being a fuzzer itself, dfuzz is a wrapper for other simple fuzzers solving few common flaws which makes automated testing a bit difficult.

Although its primary targets are configuration files, it is possible to use dfuzz to fuzz any input files.

The main problems dfuzz solves are:
  • alpha versions of fuzzers - most of the fuzzers are just alpha versions which are no longer developed or maintained
  • common format - no need to understand how to use every single underlying fuzzer
  • customizable monitoring and automatic error analysis
  • straightforward specification of what to test and which file to supply to the target
  • combination of mutation and generation of fuzzed files

Requirements

  • python >= 2.6
  • fuzzer (zzuf, autodafe, …)
  • gdb, valgrind (both are optional)

Features

  • independent of underlying fuzzer
  • highly configurable
  • built to be extendible
  • automation friendly

Supported fuzzers

  • zzuf (mutation)
  • autodafe (generation)
  • plain (debugging purposes)

Usage

  • install requirements
  • install dfuzz (for example easy_install dfuzz)
  • create a working directory
  • supply fuzz.conf file (sample follows)
  • according to the modules you want to use, create mut or gen directory in your working directory and supply a file to fuzz or a template to use
  • run dfuzz -d -o name_of_the_working_directory
  • observe output
  • if everything is fine remove the -d and -o options and run the command again
  • check the samples directory created in your working directory
  • use included incident_viewer to browser incidents if there are any

Complete documentation in docs directory.

Sample fuzz.conf file

[global]
binary=libvirtd
args=-f FUZZED_FILE --verbose
threads = 1
timeout = 2

generation  = 0
mutation    = 1
combination = 0

[generation]
modules  = dfuzz.gen.autodafe
priority = high

[mutation]
modules = dfuzz.mut.zzuf; dfuzz.mut.plain
priority = high

[combination]
modules = dfuzz.comb.simple
priority = low

In it’s simplest form, dfuzz can be used as a zzuf wrapper with enhanced detection and reporting capabilities.
