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.
Graph showing the progress of the XSS worm that impacted 2525 users on Justin.tv. Justin.tv was a video casting website with an active user base of approximately 20 thousand users. The cross-site scripting vulnerability that was exploited was that the "Location" profile field was not properly sanitized before its inclusion in a profile page.
The attack employed a technique in which the input was crafted to grow the size of the responses, leading to a proportional growth in the time taken to generate the responses, thus increasing the attack's accuracy. [21] Independent security researchers have published blog posts describing cross-site leak attacks against real-world applications.
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
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.
When this flag is set, it does not allow client-side script interaction with cookies, thereby preventing certain XSS attacks. [10] Modular shell disassociation from the kernel. Regarding SQL injection, one can use parameterized queries, stored procedures, whitelist input validation, and other approaches to help mitigate the risk of an attack. [11]
This can be done by leveraging other attacks such as cross-site scripting or by abusing rich text rendering features on a web page (for example, Gmail's email reader and WYSIWYG editor). [ 16 ] [ 17 ] This is crucial since DOM clobbering depends on the attacker being able to inject potentially benign HTML into a website.
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.
