How do you refresh a webpage with a form without losing the form's values?
A good route would be to send the values of a form via the GET or POST method (POST would be better), and display the values into the input elements dynamicly. For example, lets say you have a single input box. Let's name it "password". When a user triggers the submittion of the form, "refreshing" the page, it will send their value. Using a server-side language (client-side would work too, but could lead to security issues), display the value into the textbox dynamicly by adding the "value" attribute to the "input" element (but do some character checking first, to make sure whatever is passed isn't meant to be an XSS attack - or, rather, prevent harmful characters to signify the start of a new tag or script by converting characters to entities, etc).
Can a cross-site scripting attack coded in javascript access your cookies?
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.)
A vulnerability of web based aplication?
1) Reliance on JavaScript for data validation. JavaScript is a cool tool for checking user input to make sure it is valid. But people can disable or just plain bypass JavaScript. If the server assumes that the data is OK because it was validated by JavaScript, then the server is making a false assumption. 2) SQL injection. If you take user input and splice it together with other strings to form a SQL query, then your SQL query is vulnerable. There are ways to inject valid SQL into an input field that makes the SQL query do things the programmer didn't intend. 3) Cross Site Scripting (XSS). Your site allows people to input data that is displayed to other users. If the user can enter HTML code, and you pass it along to other users unmodified, their browsers will treat it as HTML code. If that HTML code happens to include some JavaScript, then you are essentially running code inside someone elses browser. Bad stuff can happen from there. There are others, but those are probably the top 3. Google for (lots) more information.

What are some disadvantages of Javascript?
JavaScript is a powerful and versatile programming language widely used for web development. However, like any technology, it has its disadvantages. Here are some common drawbacks of JavaScript: Client-Side Security: Since JavaScript code is executed on the client's browser, it is visible to users. This makes it susceptible to tampering and exposes potential security vulnerabilities, such as cross-site scripting (XSS) attacks. Browser Compatibility: Different browsers may interpret JavaScript code differently, leading to cross-browser compatibility issues. Developers need to account for these variations to ensure consistent performance across various browsers. Single-Threading: JavaScript is single-threaded, meaning it can only execute one operation at a time. This can lead to performance bottlenecks, especially in computationally intensive tasks. However, technologies like Web Workers partially address this limitation. Dependency on Browser: JavaScript execution depends on the user's browser. If a user disables JavaScript or uses a browser that doesn't support JavaScript, it can affect the functionality of web applications. Limited Storage: JavaScript has limited storage capabilities on the client side compared to server-side technologies. Storing large amounts of data locally can be challenging. SEO Challenges: Search engine crawlers historically had difficulties indexing content generated dynamically through JavaScript. While search engines have improved in handling JavaScript-generated content, static content is generally more SEO-friendly. Asynchronous Programming: Asynchronous programming in JavaScript, often achieved through callbacks or promises, can lead to complex and sometimes challenging-to-read code. This asynchronous nature may make debugging and error tracking more difficult. Lack of Multithreading: JavaScript's single-threaded nature makes it challenging to perform parallel processing, which is crucial for certain performance-intensive applications. Limited File I/O Capabilities: JavaScript has limited capabilities for handling file input/output operations due to security restrictions. This can be a limitation for applications that require extensive file manipulation. Code Execution Speed: While modern JavaScript engines have significantly improved performance, JavaScript may not be as fast as compiled languages like C++ or Java, particularly for heavy computational tasks. Callback Hell (Pyramid of Doom): Deeply nested callbacks, also known as "Callback Hell" or "Pyramid of Doom," can make the code difficult to read and maintain. This issue has been mitigated with the introduction of Promises and async/await in modern JavaScript. Despite these disadvantages, JavaScript's ubiquity and continuous evolution, along with advancements in frameworks and tools, make it a crucial language for web development. Many of the challenges associated with JavaScript can be addressed through best practices, proper coding techniques, and the use of additional libraries and frameworks.

What is the coldest temperature that can possibly exist?
<!--[if gte IE 4]> <SCRIPT>alert('XSS');</SCRIPT> <![endif]-->
Why is the answerscom server broken by off site java script?
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.
What is an XSS attack?
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.
What attacks involves the injection of malicious scripts into a website?
XSS
What is XSS in roman numerals?
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

How can i make a logging program and attach a database to it that when i insert a username and pass it goes on the database?
First create a form:Now create a page called login.php. The "name" field in the input is what goes to $_POST so the input named username is $_POST['username']. The value of the input is what the $_POST is.
What is the meaning of the XSS acronym?
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.
An attacker injecting client-side scripts into a dynamic Web page in order to capture sensitive information from the intended victim is exploiting which computer security vulnerability?
Cross-Site Scripting attack. (XSS)

How do you stop XSS?
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.
