Introduction To This Article:

Cybersecurity is crucial in today’s digital age. However, one aspect of it involves protecting against different types of attacks on websites and web applications. Although, two types of attacks are common  (Self-XSS and Reflected XSS). These attacks might sound complicated, but let’s break them down. Anyhow, In this article, we will discuss Self XSS VS Reflected XSS.

Self XSS VS Reflected XSS – Self-XSS :

Imagine you’re browsing a website, and you come across a message that says, “Copy and paste this code into your browser’s address bar to see a hidden message!”. This is the heart of a Self-XSS attack. Self-XSS tricks users into running malicious code themselves. When you paste the code into the address bar, you’re actually executing the attacker’s code, giving them access to your account or personal information. Additionally, It’s like willingly opening the door for the bad guys.

Self XSS VS Reflected XSS – Reflected XSS:

Reflected Cross-Site Scripting (XSS) is a security vulnerability where a website unintentionally runs malicious code sent by a hacker through manipulated links or inputs. Moreover, this leads to unauthorized access to data or actions on a user’s behalf.

For Example, imagine you’re searching for movie reviews on a website. If a hacker tricks you into clicking a link. On the other hand, the website might unknowingly display that code in the search results. When you view these results, the malicious code activates in your browser, allowing the hacker to steal your login details or perform actions without your knowledge. This occurs due to the website failing to properly validate and filter user inputs.

Self XSS VS Reflected XSS – Key Differences:

1. User Involvement:
   • Self-XSS: Requires the user to willingly paste malicious code into their browser.
   • Reflected XSS: Tricks the user into clicking a link, with the malicious code executed automatically.
2. Execution:
   • Self-XSS: The user executes the attacker’s code by pasting it into the browser’s console.
   • Reflected XSS: The website unknowingly reflects the attacker’s code back to the user’s browser, executing it there.
3. Attack Method:
   • Self-XSS: Often involves social engineering tactics to persuade users to run the code themselves.
   • Reflected XSS: Takes advantage of weak website checks to put harmful code onto the page by fooling the site’s defenses.

Conclusion:

Both Self-XSS and Reflected XSS are attempts to exploit security vulnerabilities in websites or web applications. However, the key difference lies in how the attacks are executed. Self-XSS relies on user cooperation, while Reflected XSS leverages vulnerabilities in a website’s input handling to execute malicious code without the user’s direct involvement. However, to stay safe, users should avoid executing any code provided by unknown sources and website developers should implement proper input validation to prevent these vulnerabilities.
