The approach to this challenge was completely different from the past two months, as the vulnerable component was on the backend, forcing us to approach it as a black box scenario. The page presents a simple submittable get form providing the open and payload parameters. To reach that from the UI, a user has to […]

Introduction Github project: https://github.com/kiks7/KRWX During the last few months/year I was studying and approaching the Kernel Exploitation subject and during this journey I developed few tools that assissted me (and currently assist) on better understanding specific topics. Today I want to release my favourine one: KRWX (Kernel Read Write Execute). It is a simple LKM […]

Introduction I was searching for a vulnerability that permitted me to practise what I’ve learned in the last period on Linux Kernel Exploitation with a “real-life” scenario. Since I had a week to dedicate my time in Hacktive Security to deepen a specific argument, I decided to search for a public vulnerability without a public […]

Tl;DrThe Engintron plugin for CPanel presents a default configuration which could expose applications to account takeover and / or sensitive data exposure due to cache poisoning attacks. Whenever a client sends a request to a web server, the received response is processed and served by the back-end service each time. In case of an high […]

A few months ago me and my friend Jacopo Tediosi made an interesting discovery about an Akamai misconfiguration that allowed us to earn more than 46,000 dollars. Our research highlighted how manipulating a particular HTTP header made it possible to change the way how proxies communicated with each other and how this allowed us to […]

Introduction In the past few weeks, I worked with @LukeGix (checkout his blog post on the same vulnerability here) to exploit the CVE-2022-2602, a very interesting bug from multiple perspectives without a public exploit, that impacts the io_uring subsystem with an Use-After-Free vulnerability handling registered file descriptors.We used a Data-Only attack against kernel version 5.15.74 […]

The bug bounty program Intigriti hosts an XSS challenge every month. This time, the challenge was about bypassing CSP by reloading a VueJS instance, getting able to exploit a client side template injection. My solution can be summarized in 4 main steps: Finding reflection and achieving HTML Injection Accessing an abusable piece of code, containing […]

A few months ago I found out that the dutch government is hosting a bug-bounty program that covers a lot of assets from their infrastructures. The program scope available at https://www.communicatierijk.nl/vakkennis/r/rijkswebsites/verplichte-richtlijnen/websiteregister-rijksoverheid appears to be really wide, with more than 1000 targets, that allowed to find some interesting application by running some basic passive subdomain enumeration […]

Il mio percorso professionale è iniziato nel mondo delle TLC nel 1983, tra le braccia della Mamma dei Fili nazionale: da lì in poi ho avuto la fortuna sfacciata di partecipare a più o meno tutte le corse all’oro legate alla continua rivoluzione tecnologica. Dai fosfori verdi della CLI del terminale 3270 fino a Chat […]

I miei primi approcci nel campo dell’informatica risalgono circa alla fine degli anni ’90. Avevo poco più di cinque anni quando ho iniziato a mettere le mani sul computer dei miei genitori. Già allora ero molto curioso e mi affascinava esplorare quel vecchio sistema operativo che mi portava a perdermi tra le cartelle del file […]

In the vast realm of software development, the Python Package Index has long been a trusted repository for Python packages. However, even the most reliable platforms are not immune to the ever-evolving landscape of cyber threats. My recent investigation led me to stumble upon a malicious package lurking within PyPI, disguised as a seemingly “innocent […]
