# Cross-Site Scripting (XSS)
|
|
|
|
## Description
|
|
Cross-Site Scripting (XSS) attacks are a type of injection in which malicious scripts are injected into otherwise benign and trusted websites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user.
|
|
|
|
## Types of XSS
|
|
- **Reflected XSS**: Script is reflected off the web server
|
|
- **Stored XSS**: Script is permanently stored on the target server
|
|
- **DOM-based XSS**: Vulnerability exists in client-side code
|
|
|
|
## Common Attack Vectors
|
|
- Input fields
|
|
- URL parameters
|
|
- HTTP headers
|
|
- File uploads
|
|
- Comment sections
|
|
|
|
## Testing Approach
|
|
Submit JavaScript code in various input points and observe if the code gets executed in the browser.
|
