Fuzzing scripts

When on, register_globals will inject your scripts with all sorts of variables, like request variables from HTML forms. This coupled with the fact that PHP doesn't require variable initialization means writing insecure code is that much easier. It was a difficult decision, but the PHP community decided to disable this directive by default. simple fuzz is exactly what it sounds like – a simple fuzzer. don’t mistake simple with a lack of fuzz capability. this fuzzer has two network modes of operation, an output mode for developing command line fuzzing scripts, as well as taking fuzzing strings from literals and building strings from sequences. A fuzzing technique will try every possible type of random input to an application to see if a security problem can be found with the application’s programming.

Finding uncovered function calls with bncov scripts. So to bring this back to our original goal of finding additional functionality to add to the fuzz harness, we should investigate why these function calls didn’t happen during our fuzzing run, and then decide if there’s any changes we can make to our harness to make it cover more code paths.

Wicked Cool Shell Scripts, 2nd Edition is a collection of fun tools for sysadmins, web developers, and every Linux user.

Fuzzing your programs can give you a quick view on their overall robustness and help you find and fix critical bugs. It’s ultimately a black box technique, requiring no access to source code, but it can still be used against software for which you do have source code. Comparing the benchmarks of a fuzzing job running on the Edison and a few servers and workstations, calculations of cost-efficiency worked out well for this tiny x86 system on module. It’s worth noting that the overall fuzzing speed and performance is going to be largely determined by how fast your test harness is. A large, intricate Python-based test harness is going to run much slower than a tight, optimized C-based harness. Make sure to consider this if you plan on running extensive, long-running fuzzers. simple fuzz is exactly what it sounds like – a simple fuzzer. don’t mistake simple with a lack of fuzz capability. this fuzzer has two network modes of operation, an output mode for developing command line fuzzing scripts, as well as taking fuzzing strings from literals and building strings from sequences.
