In this video, I’m trying to find the famous java Log4Shell RCE (CVE-2021-44228) using fuzzing. I’m targeting apache log4j2 version 2.14.1 and I’m using Jazzer, the Java fuzzer developed by Code Intelligence. I will show and give you everything to reproduce the same at home 😉 Don’t forget to patch the log4j security vulnerability by switching to log4j2 version 2.15.0
