OneGadget

When playing ctf pwn challenges we usually need the one-gadget RCE (remote code execution),
which leads to call execve('/bin/sh', NULL, NULL).

This gem provides such gadgets finder, no need to use objdump or IDA-pro every time like a fool 😉

To use this tool, type one_gadget /path/to/libc in command line and enjoy the magic 😆

Installation

Available on RubyGems.org!

Note: requires ruby version >= 2.1.0, you can use ruby --version to check.

Supported Architectures

Implementation

OneGadget uses symbolic execution to find the constraints of gadgets to be successful.

The article introducing how I develop this tool can be found on my blog.

Gadget (computer science) – Wikipedia

In computational complexity theory, a gadget is a subset of a problem instance that simulates the behavior of one of the fundamental units of a different computational problem. Gadgets are typically used to construct reductions from one computational problem to another, as part of proofs of NP-completeness or other types of computational hardness. The component design technique is a method for constructing reductions by using gadgets.[1]

Szabó (2009) traces the use of gadgets to a 1954 paper in graph theory by W. T. Tutte, in which Tutte provided gadgets for reducing the problem of finding a subgraph with given degree constraints to a perfect matching problem. However, the “gadget” terminology has a later origin, and does not appear in Tutte’s paper.[2][3]

Example[edit]

NP-completeness reduction from 3-satisfiability to graph 3-coloring. The gadgets for variables and clauses are shown on the upper and lower left, respectively;

You are Not a Gadget: A Manifesto – Jaron Lanier

Jaron Lanier, a Silicon Valley visionary since the 1980s, was among the first to predict the revolutionary changes the World Wide Web would bring to commerce and culture. Now, in his first book, written more than two decades after the web was created, Lanier offers this provocative and cautionary look at the way it is transforming our lives for better and for worse.

The current design and function of the web have become so familiar that it is easy to forget that they grew out of programming decisions made decades ago. The web’s first designers made crucial choices (such as making one’s presence anonymous) that have had enormous—and often unintended—consequences. What’s more, these designs quickly became “locked in,” a permanent part of the web’s very structure.

Lanier discusses the technical and cultural problems that can grow out of poorly considered digital design and warns that our financial markets and sites

The Pioneer Woman Vintage Floral Gadget Set, 20 Piece – Walmart.com

Everything that this set comes with is needed for a kitchen. Not all of them are designed well, but the ideas for them are great. 20 pieces include a solid wood cutting board (13inches by 9inches). The cutting board should be hand washed since it is wood. A whisk, melamine measuring pitcher, 4 piece measuring spoons, 4 piece measuring cups, melamine resting spoon, a 4 piece silicone spatulas with wood handles (hand wash the wood handles), a 4 inch paring knife with sheath and a 6.5 inch knife with sheath. I really like that the knives come with sheath. It is so much safer in the knife drawer to keep the blades covered. I like the design on the side of the blade. I had never seen this before, and it adds character.

The spatulas are my favorite part of the set. 2 are straight edged and 2 are cupped.

Sales of kitchen gadget increase by 1600 per cent

From blast chillers to ice cream machines, every season of MasterChef seems to bring a kitchen gadget into the limelight.

This season, it’s the hibachi grill.

Fans of the cooking competition have become well accustomed to seeing at least one, if not multiple contestants cooking on these portable Japanese grills every episode.

Just this week, Simon Toohey won the judges over with his burnt cucumber dish on Monday, while Sarah Clare lost a charred duck oesophagus to the grill during Wednesday night’s Mystery Box. Then on Thursday night’s hibachi-related cook, Sarah Tiong unfortunately seared her coral trout a few shades too dark, and lost her chance at immunity. It instead went to Jess Liemantara, who won with her non-hibatchied 65-degree egg with turmeric noodles and chilli oil.

Humble home cooks can also get in on the hibachi action.
