Background
bettercap is a powerful, flexible, and portable network attack and monitoring tool that allows users to perform various network-related tasks. It is widely used for penetration testing, network analysis, and security assessments. The tool includes a variety of modules, one of which is the zerogod IPP Service. This service is responsible for handling IPP (Internet Printing Protocol) requests. The vulnerability in question affects versions of bettercap up to 2.41.5, specifically in the ippReadChunkedBody function, which processes chunked HTTP requests.
Vulnerability Detail
