The HTTP TRACE response includes all the HTTP headers including authentication data and HTTP cookie contents, which are then available to the script. In combination with cross domain access flaws in web browsers , the exploit is able to collect the cached credentials of any web site, including those utilizing SSL .
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.
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 ...
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.
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.
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 .
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
Well, I would agree that cross-site scripting could be used to refer to an attack. However, there is a vulnerability at the core of it which allows the attack to succeed. I strongly disagree with the assertion that it's a "input validation" flaw, because the real problem output-encoding.
