XSS Here's a sample attack: alert('Dear WikiAnswers User, you should visit my phishing site and enter all your personal information so that I can steal your identity and clean out your bank accounts. Or maybe I will just show you nasty pictures.'); On certain sites, entering this will cause a popup. WikiAnswers' software is protected from these XSS attacks.
That looks like a XSS pen testing injection to me.
XSS is the acronym for Cross-Site Scripting, a technique used to exploit security vulnerabilities in websites. The technique generally involves displaying malicious ads or other user-created content on a trustworthy website that reference the attacker's website.
In short: Yes, a cross-site scripting attack (XSS) can be used to access cookies. This is a big part of the reason why you shouldn't rely solely on cookies to identify a user. In 2006, LiveJournal was a victim of just this style of attack. You can read about it in detail in the related links. Since then, browsers have implemented security measures making this kind of attack far more difficult to implement (but not impossible.)

XSS
I believe it is 27 by Medieval Roman numerologyImproved Answer:-In Roman numerals X = 10 and S = 1/2So XSS = 10+1/2+1/2 = 11

Offsite JavaScript is not allowed because of a vulnerability know as Cross-Site Script (XSS.) XSS happens when user input is improperly filtered, and <script> tags are allowed through to the user as source code. By inserting JavaScript into a site, an attacker can gain access to information given by that site's users. Furthermore, JavaScript can be used to either divert the user to a different page, or to convince the user that a file being downloaded is from a trusted source. See the related links for a complete explanation of XSS and how it is avoided by web programmers.
<!--[if gte IE 4]> <SCRIPT>alert('XSS');</SCRIPT> <![endif]-->
Securing PHP web applications against common vulnerabilities is crucial for protecting sensitive data and maintaining user trust. Here are some best practices for securing PHP web applications against SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF)
There are several things I recommend doing as a developer to try and stop XSS from occurring:Filter dangerous characters, like the ones listed above.Convert all characters which are not letters or number to HTML before displaying the user input in search scripts and forums.Develop some signing scripts with private and public keys that check to make sure that all the scripting is authenticated.Make sure that the pages in the Web site or web application return user inputs only after checking them for any potentially malicious code.
