In fact, you solve the majority of our XSS labs by invoking alert() in a simulated victim's browser. It's long been common practice to use the alert() function for this purpose because it's short, harmless, and pretty hard to miss when it's successfully called.

You can confirm most kinds of XSS vulnerability by injecting a payload that causes your own browser to execute some arbitrary JavaScript. If you're already familiar with the basic concepts behind XSS vulnerabilities and just want to practice exploiting them on some realistic, deliberately vulnerable targets, you can access all of the labs in this topic from the link below. When the malicious code executes inside a victim's browser, the attacker can fully compromise their interaction with the application. If the victim user has privileged access within the application, then the attacker might be able to gain full control over all of the application's functionality and data.Ĭross-site scripting works by manipulating a vulnerable web site so that it returns malicious JavaScript to users. Cross-site scripting vulnerabilities normally allow an attacker to masquerade as a victim user, to carry out any actions that the user is able to perform, and to access any of the user's data. It allows an attacker to circumvent the same origin policy, which is designed to segregate different websites from each other.

In this section, we'll explain what cross-site scripting is, describe the different varieties of cross-site scripting vulnerabilities, and spell out how to find and prevent cross-site scripting.Ĭross-site scripting (also known as XSS) is a web security vulnerability that allows an attacker to compromise the interactions that users have with a vulnerable application. Bypassing a CSP with an AngularJS sandbox escape.
