HTML Injection vs. XSS
What's the Difference?
HTML Injection and XSS (Cross-Site Scripting) are both types of web security vulnerabilities that allow attackers to inject malicious code into a website. However, HTML Injection typically involves injecting code directly into the HTML of a webpage, while XSS involves injecting code into a website's client-side scripts, such as JavaScript. XSS is generally considered more dangerous as it allows attackers to execute scripts in the context of a user's browser, potentially stealing sensitive information or performing unauthorized actions on behalf of the user. Both vulnerabilities can be mitigated by properly sanitizing user input and implementing security best practices.
Comparison
| Attribute | HTML Injection | XSS |
|---|---|---|
| Vulnerability Type | Client-side | Client-side |
| Attack Vector | Form inputs, URL parameters | Form inputs, URL parameters, cookies |
| Impact | Can modify the structure of the page | Can execute malicious scripts, steal cookies |
| Prevention | Input validation, output encoding | Input validation, output encoding, Content Security Policy (CSP) |

Introduction
HTML Injection and Cross-Site Scripting (XSS) are two common web security vulnerabilities that can have serious consequences if not properly addressed. While both involve injecting malicious code into a web application, there are key differences between the two that make them distinct threats. In this article, we will explore the attributes of HTML Injection and XSS, highlighting their similarities and differences.
HTML Injection
HTML Injection is a type of vulnerability that occurs when an attacker is able to inject malicious HTML code into a web page. This can happen when user input is not properly sanitized or validated by the application. The injected code can alter the appearance of the web page, redirect users to malicious sites, or steal sensitive information. HTML Injection can be used to deface websites, spread malware, or launch phishing attacks.
One common example of HTML Injection is when an attacker is able to inject a
