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 ...
HTTP header injection is a general class of web application security vulnerability which occurs when Hypertext Transfer Protocol (HTTP) headers are dynamically generated based on user input. Header injection in HTTP responses can allow for HTTP response splitting , session fixation via the Set-Cookie header, cross-site scripting (XSS), and ...
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
However, trusting non-validated user data can frequently lead to critical vulnerabilities [15] such as server-side Side Template Injections. 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 ...
Cache-timing attacks rely on the ability to infer hits and misses in shared caches on the web platform. [54] One of the first instances of a cache-timing attack involved the making of a cross-origin request to a page and then probing for the existence of the resources loaded by the request in the shared HTTP and the DNS cache.
Self-XSS (self cross-site scripting) is a type of security vulnerability used to gain control of victims' web accounts. In a Self-XSS attack, the victim of the attack runs malicious code in their own web browser, thus exposing personal information to the attacker.
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.
