            How to fuzz test API as a whole and not with file inputs?
            Asked 2022-Mar-09 at 10:02

            I'm learning my way around fuzz testing C applications. As I understand it, most of the time when fuzzing, one has a C function that takes/reads files. The fuzzer is given a valid sample file, mutates it randomly or with coverage heuristics, and executes the function with this new input.

            But now I don't want to fuzz a function that takes file inputs but a few functions that together make up an API. For example:

            ...

            ANSWER

            Answered 2022-Feb-24 at 20:29

            To answer my own question:

            Yes, that's how API fuzzing can be done. For consuming the data bytewise the functions provided by libFuzzer #include (C++) could be used. Problem with this: The crash dump and fuzzer corpus won't be human readable.

            For a more readable fuzzer, implementing a structure aware custom data mutator for libFuzzer is beneficial.

            I used the premade data mutator libprotobuf-mutator (C++) to fuzz the example API. It generates valid input data based on a protocol buffer definition and not just (semi) random bytes. It does make the fuzzing a bit slower though. The bug in the given contrived example API was found after ~2min, compared to ~30secs with the basic byte consuming setup. But I do think that it would scale much better for larger (real) API's.

            How is Symbolic Execution different from Whitebox Fuzzing?
            Asked 2021-Nov-08 at 16:13

            I do not understand how symbolic execution is different from Whitebox fuzzing? From what I understand, Whitebox Fuzzers symbolically execute the code with some initial input format. Additionally, it will be helpful if someone could differentiate between these two forms with reference to KLEE and AFL tools.

            ...

            ANSWER

            Answered 2021-Nov-08 at 16:13

            Whitebox fuzzing can be done not only with symbolic execution. SAGE from Microsoft Research is an example of a whitebox fuzzer that uses concolic execution, also called dynamic symbolic execution, see NDSS08.

            Yes, Whitebox Fuzzers get some seed/seeds (initial input/inputs) and symbolically execute the code with these. Concolic fuzzers also run the code with these inputs in parallel with symbolic execution.

            KLEE is a whitebox fuzzer that uses symbolic execution.

            AFL is a greybox fuzzer - it uses internal structure information only to calculate coverage and not to get new paths. There are tools for AFL that get constants from comparisions in the code and add these to AFLs dictionaries, but this is still not whitebox fuzzing.

            The syn crate made a breaking change in version 1.0.58, when it renamed a module that was not meant to be used by other crates. The enum_dispatch crate was one that erroneously was using this module and thus was broken but later fixed in version 0.3.5 (see the relevant issue).

            I don't know where exactly in your dependency tree syn and enum_dispatch sit, but I recommend updating enum_dispatch to a newer version.

            This sounds like you're using an old version of python, specifically a version 3.5 or earlier.

            What does python3 --version say?

            If possible, you should upgrade to a version of python 3.6 or higher, as python 3.5 is no longer supported.

            If that isn't possible, don't use f-string syntax. Instead, you could do something like this:

            • are you sure you read serialized information of your datatype A?
            • are you sure to have read at least sizeof(A) bytes?
            • are you sure your type A is (trivially) serializable? (e.g. what if A contains a pointer to another object)
