Web-applications somewhere or the other allow its users to upload a file, whether its an image, a resume, a song, or anything specific. Thereby, he thus waits, until the user pulls the payload out from the database and renders it up into his/her browser. So, in order to exploit such vulnerabilities – He blindly deploys up the series of malicious payloads over onto the web-applications, and thus the application stores them into the database. either by the administrator or by someone else. Many times the attacker does not know where the payload will end up and if, or when, it will get executed and even there are times when the injected payload is executed in a different environment i.e. So let’s try to exploit the vulnerable labs over The Portswigger Academy and bWAPP in order to capture up the authenticated cookie of the users and the server’s remote shell.īut before making our hands wet with the exploits, let’s understand what is Blind XSS? Blind XSS I guess you’re now having a clear vision about -“What is XSS” and “How it occurs”. “XSS” thus has been classified into three main categories : So, when any user visits that website, the XSS suffering web-page will deliver the malicious JavaScript code directly over to his browser without his knowledge. In this attack, the users are not directly targeted through a payload, although the attacker shoots the XSS vulnerability by inserting a malicious script into a web page that appears to be a genuine part of the website. Credential Capturing with Burp CollaboratorĬross- Site Scripting is a client-side code injection attack where malicious scripts are injected into trusted websites.Session Hijacking with Burp Collaborator.I recommend, to revisit our previous article for better understanding, before going deeper with the attack scenarios implemented in this section. “Are you one of them, who thinks that Cross-Site Scripting is just for some errors or pop-ups on the screen?” Yes? Then today in this article, you’ll see how an XSS suffering web-page is not only responsible for the defacement of the web-application but also, it could disrupt a visitor’s privacy by sharing the login credentials or his authenticated cookies to an attacker without his/her concern.
