Fuzzing Farm #4: 0-dayエクスプロイトの開発 [CVE-2022-24834]
著者：Dronex, ptr-yudai はじめに この記事は、Fuzzing Farmシリーズ全4章のパート4で、パート3の記事「Fuzzing Farm #3: パッチ解析とPoC開発」の続きです。 Fuzzing Farmチームでは、前回の記事で紹介したように、1-dayエクスプロイトだけでなく0-dayエクスプロイトの開発にも取り組んでいます。Fuzzing Farmシリーズ最終章では、弊社エンジニアが発見した0-dayと、そのエクスプロイト開発について解説します。 我々は1年以上前の2022年4月の段階で、CVE-2022-24834に該当するRedisの脆弱性を発見し、RCE（Remote Code Execution; 任意コマンド実行）エクスプロイトの開発を完了していました。ベンダ側も修正を急いでくれましたが、利用者側の対応に時間を要したため、前回パート3の記事から今回の投

Fuzzing - Wikipedia
In programming and software development, fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. The program is then monitored for exceptions such as crashes, failing built-in code assertions, or potential memory leaks. Typically, fuzzers are used to test programs that take structured inputs. Th
Optionsbleed - HTTP OPTIONS method can leak Apache's server memory | The Fuzzing Project
If you're using the HTTP protocol in everday Internet use you are usually only using two of its methods: GET and POST. However HTTP has a number of other methods, so I wondered what you can do with them and if there are any vulnerabilities. One HTTP method is called OPTIONS. It simply allows asking a server which other HTTP methods it supports. The server answers with the "Allow" header and gives

Announcing OSS-Fuzz: Continuous Fuzzing for Open Source Software
The latest news and insights from Google on security and safety on the Internet
Fuzzing is a powerful strategy to find bugs in software. The idea is quite simple: Generate a large number of randomly malformed inputs for a software to parse and see what happens. If the program crashes then something is likely wrong. While fuzzing is a well-known strategy, it is surprisingly easy to find bugs, often with security implications, in widely used software. Memory access errors are t

This tutorial introduces the basics of fuzzing in Go. With fuzzing, random data is run against your test in an attempt to find vulnerabilities or crash-causing inputs. Some examples of vulnerabilities that can be found by fuzzing are SQL injection, buffer overflow, denial of service and cross-site scripting attacks. In this tutorial, you’ll write a fuzz test for a simple function, run the go comma

And we still got massively dunked on by the fuzzer. Just absolutely destroyed. I was starting to pivot off of rust-minidump work because I needed a bit of palette
50 CVEs in 50 Days: Fuzzing Adobe Reader - Check Point Research

The number of new vulnerabilities reported that year was around 14,000, which is over twice the number from the year before (see table below). The probable reason for this is the increased popularity of automatic vulnerability finding tools, also known as “fuzzers”. The mere

Compiler fuzzing, part 1
Much has been written about fuzzing compilers already, but there is not a lot that I could find about fuzzing compilers using more modern fuzzing techniques where coverage information is fed back into the fuzzer to find more bugs. If you know me at all, you know I'll throw anything I can get my hands on at AFL. So I tried gcc. (And clang, and rustc -- but more about Rust in a later post.) Levels o

Fuzzing vs property testing
Fuzzing and property testing both involve generating random inputs, and then checking if a program misbehaves on those inputs. This description should probably leave you raising your eyebrow slightly: if you start being vague enough, lots of entirely different things sound similar. But there are some real similarities between these two techniques. Let’s start with the hard distinction between the

For some time I’ve wanted to play with coverage-guided fuzzing. Fuzzing is a powerful testing technique where an automated program feeds semi-random inputs to a tested program. The intention is to find such inputs that trigger bugs. Fuzzing is especially useful in finding memory corruption bugs in C or C++ programs. Normally it's recommended to pick a well known, but little explored, library that
