Cross-site scripting (XSS) [a] is a type of security vulnerability that can be found in some web applications. XSS attacks enable attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy.
XSS worms exploit a security vulnerability known as cross site scripting (or XSS for short) within a website, infecting users in a variety of ways depending on the vulnerability. Such site features as profiles and chat systems can be affected by XSS worms when implemented improperly or without regard to security. Often, these worms are specific ...
Samy (also known as JS.Spacehero) is a cross-site scripting worm that was designed to propagate across the social networking site MySpace by Samy Kamkar. Within just 20 hours [1] of its October 4, 2005 release, over one million users had run the payload [2] making Samy the fastest-spreading virus of all time. [3] The message on a victim's profile
The "XSS" part of the name comes from the abbreviation for cross-site scripting, because both attacks result in malicious code running on a legitimate site. However, Self-XSS has much less impact than most other XSS vulnerabilities because it relies on social engineering. Additionally, the risk of Self-XSS arising from using the web developer ...
Cross-site request forgery is an example of a confused deputy attack against a web browser because the web browser is tricked into submitting a forged request by a less privileged attacker. CSRF commonly has the following characteristics: It involves sites that rely on a user's identity. It exploits the site's trust in that identity.
Cross-site leaks, also known as XS-leaks, is an internet security term used to describe a class of attacks used to access a user's sensitive information on another website. Cross-site leaks allow an attacker to access a user's interactions with other websites. This can contain sensitive information.
While this vulnerability is similar to cross-site scripting, template injection can be leveraged to execute code on the web server rather than in a visitor's browser. It abuses a common workflow of web applications, which often use user inputs and templates to render a web page. The example below shows the concept.
HTTP response splitting is a form of web application vulnerability, resulting from the failure of the application or its environment to properly sanitize input values.It can be used to perform cross-site scripting attacks, cross-user defacement, web cache poisoning, and similar exploits.
