Summary
Cross-Site Scripting (XSS) is an attack wherein an attacker injects malicious JavaScript code into a website and targets its users to steal sensitive data like cookies, redirect users to malicious websites, or even take complete control of their session.
There are two types of XSS attacks: Reflected XSS relies on injecting malicious code into a website’s URL, which gets reflected/executed as and when the victim clicks on the malicious link.
Stored XSS, on the other hand, involves injecting malicious code into a website’s database and every time a user visits the webpage, the stored malicious code gets executed.
Such an attack can prove to be extremely dangerous as it can bypass a user’s defenses and provide an attacker access to their data without their knowledge.
It is essential to have good security practices and vigilant coding to prevent such attacks. Furthermore, it is always recommended to scrutinize inputs from users and validate them to ensure they do not contain any harmful scripts.
