Hello! Another week, another writeup! Wish I could always keep publishing with this rate ;) This time I worked on Ziko2 boot2root, as usual from Vulnhub. How does Author describe his challange?

Zico’s Shop: A Boot2Root Machine intended to simulate a real world cenario Disclaimer: By using this virtual machine, you agree that in no event will I be liable for any loss or damage including without limitation, indirect or consequential loss or damage, or any loss or damage whatsoever arising from loss of data or profits arising out of or in connection with the use of this software. TL;DR - You are about to load up a virtual machine with vulnerabilities. If something bad happens, it’s not my fault. Level: Intermediate Goal: Get root and read the flag file Description: Zico is trying to build his website but is having some trouble in choosing what CMS to use.
