If you want to know the goal of an XSS attack, first you need to know what is an XSS attack, how does it work, and then realize its features as well as its dangers, finally you would figure out the goal of such an attack. You will also become familiar with its different types and the common destructions it could make for you. You probably are curious about the history of this attack, too, and where does this abbreviation come from; if you are, follow this article till the last paragraph.
What is a Cross-Site Scripting attack?
One of the cyber threats to websites or applications is rush. This stands for Cross-Site Scripting. Cross-Scripting Attack is a common type of code injection that rushes targets are web applications, and it does destruct them by detecting their vulnerabilities and injecting malicious code. In this attack, web applications are not directly affected, and instead, users who interact with such sites or applications are potential targets. Its attacks occur when a hacker uses a browser-side scripting style to send malicious code to a victim through a web application. Attackers take advantage of vulnerabilities in web applications that could cause a successful attack.
An example of Cross-Site Scripting rush
- Obtaining authentication information
- Obtaining private user information
- Sending fake requests due to user access level
- Create forms and styles on a user-trusted website to deceive a user
What is the goal of Cross-Site Scripting strafe?
Cross-Site Scripting types
This vulnerability was initially divided into two types, Stored and Reflected (continuous and non-continuous). But in 2005, Mr. Amit Klein defined the third type of XSS, DOM-based. In this section, the purpose is to introduce the types of this, so we will mention the names of these three types, and in the continuation of the article, we will define these three types in detail.
- Server XSS
Server Cross-Site Scripting occurs when an invalid user succeeds in forcing a website to generate data in an HTTP response. The source of this data can be stored from a request or location. Therefore, this Server can be divided into two types: Stored Server and Reflected Server. In this type of attack, malicious code is provided by the Server, and the browser simply executes the code, which means that any script is valid from the browser.
- Client XSS
Protection against Cross-Site Scripting strafe
Applications can be challenging in terms of the complexity of cross-scripting. Therefore, it is difficult to secure them against cross-scripting attacks. But with proper precautions, you can protect your web application from these attacks.
- You must filter the input received from the user
- With Web Vulnerability Scanner tools, you can scan your web application for potential Cross-Site Scripting vulnerabilities.
- You can also implement a Content Security Policy (CSP) to curb the harmful effects of any other strafe vulnerabilities.
How to prevent or reduce the risk of these bugs or vulnerabilities
How to completely prevent XSS requires a lot of research on the performance of the website and depending on the design of the program, which is not the purpose of this article. Here are some ways to prevent and secure websites in general, and if you pay attention to these, the application will be largely safe against XSS vulnerabilities.
- Lack of support for HTTP TRACE
- Input validation
Validation of inputs is terms and conditions that a programmer must set according to the needs of an input. An example would be not sending letters in fields that only need numbers.
- Escape from suspicious characters
It means censoring some of the characters suspected of attacking.
- Sanitize inputs when rendering them
Doing sanitize while storing information can be problematic because the intruder can usually find a way to store information that Sanitize does not do.
You now know what is XSS attack and its goals. You may have realized that it is considered a dangerous attack that may cause some problems for you. So pay attention to protection ways mentioned above, to prevent your information from getting stolen.Click to audit your website SEO
