May 11, 2021. Simple Data Exfiltration Through XSS. Written by Drew Kirkpatrick. During a recent engagement, I found a cross-site scripting (XSS) vulnerability in a legal document management application and created a quick and dirty document exfiltration payload.
Jul 6, 2023 TrustedSec regularly creates weaponized XSS payloads on engagements to perform malicious actions such as stealing documents we shouldn't have access to. One specific form of XSS vulnerability that is particularly difficult to exploit is a reflected POST based XSS vulnerability.
May 2, 2023 Having small XSS payloads or ways to shorten your payloads ensures that even the smallest unencoded output on a site can still lead to account compromise. A typical image tag with a onerror attribute takes up around 35 characters by itself.

Nov 2, 2023 How do you use malicious JavaScript to attack an application you know nothing about? Application penetration testers often create custom weaponized JavaScript payloads to demonstrate potential impact to clients. Documents are stolen, privileges escalated, or account transfers initiated, depending on the client's crown jewels.

Sep 29, 2020 In a prior webinar on creating weaponized Cross-Site Scripting (XSS) payloads, I mentioned that XSS payloads (written in JavaScript) could not change the HTTP Referer header. Malicious requests made through an XSS payload will often have an unexpected Referer header that does not generally make sense in the normal workflow of the application.
Tricks for Weaponizing XSS - TrustedSec TrustedSec. Why HttpOnly Isn't Enough. There are multiple articles on the Internet stating that the HttpOnly flag provides a false sense of security as an attacker is unlikely to wait several hours for a user to trigger the payload and obtain a session token.

on XSS Protection from various organization, researchers, websites, and my own experience. This document follows a simple language and justifying explanations that helps a developer to implement the correct XSS defense and to build a secure web application that prevents XSS vulnerability and Post XSS attacks.
May 21, 2019 Privasec s Consultant Sajeeb Lohani has released the second article of his new Weaponising Series, after a great response on Weaponising AngularJS bypass. The article highlights techniques of weaponising staged cross-site scripting (XSS) payloads. Check out the full article here.
Jul 7, 2022 We'll use a reflected XSS vulnerability to frame the application login page in the IFrame trap, scrape the credentials from the login form as the victim types their credentials, and then exfiltrate those credentials to a third-party server.

Mar 28, 2023 In some cases, hackers may even use XSS vulnerabilities to create fake login pages that look identical to the real thing, tricking users into entering their credentials. Example of a Weaponized XSS. In the following video, I demonstrate how an attacker can replace the legitimate page content of a website with a fake page using an XSS vulnerability.

Overview. Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted websites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user.
