Commandline Injection

The following values are replaced with the specific values at runtime.

  • {input}: Path to the input file being processed in the current event
  • {crashes}: Path to write crashes
  • {input_corpus}: Path to the input corpus directory
  • {generated_inputs}: Path to the generated inputs directory
  • {target_exe}: Path to the target binary
  • {target_options}: Target options (recursively expanded)
  • {output_dir} : Path to the output directory as defined by the task
  • {input_file_name}: the input file name with the extension (available wherever input is available)
  • {input_file_name_no_ext}: the input file name without the extension (available wherever input is available)
  • {runtime_dir}: Path to the runtime directory for the task
  • {tools_dir}: Path to the task specific tools directory

Example

Assume the following:

  • supervisor_options is: "a", "{target_options}", "b"
  • target_options is: "c", "{target_exe}"
  • target_exe is: "d"

The resulting supervisor_options is: "a", "c", "d", "b"

Uses

These are currently used in the following tasks:

  • libfuzzer_fuzz: target_exe, target_options, input_corpus, crashes
  • libfuzzer_crash_report: target_exe, target_options, input
  • libfuzzer_merge: target_exe, target_options, input_corpus
  • libfuzzer_coverage: None
  • generic_analysis: input, target_exe, target_options, analyzer_exe, anayzer_options, output_dir, tools_dir
  • generic_generator: generated_inputs, input_corpus, tools_dir, generator_exe, generator_options, target_exe, target_options, input
  • generic_supervisor: crashes, runtime_dir, target_exe, target_options, input_corpus, input, supervisor_exe, supervisor_options, tools_dir
  • generic_merge: input, input_corpus, output_dir, target_exe, target_options, supervisor_exe, supervisor_options, tools_dir
