uniFuzzer: A fuzzing tool for closed-source binaries

uniFuzzer

uniFuzzer is a fuzzing tool for closed-source binaries based on Unicorn and LibFuzzer. Currently, it supports fuzzing 32-bits LSB ELF files on ARM/MIPS, which are usually seen in IoT devices.

Features

• very little hack and easy to build
• can target any specified function or code snippet
• coverage-guided fuzzing with considerable speed
• dependence resolved and loaded automatically
• library function override by PRELOAD

uniFuzzer uses the following environment variables as parameters:

• UF_TARGET: Path of the target ELF file
• UF_PRELOAD: Path of the preload library. Please make sure that the library has the same architecture as the target.
• UF_LIBPATH: Paths in which the dependent libraries reside. Use : to separate multiple paths.
