Technical Details
Cross-site scripting is a vulnerability that allows an attacker to target scripts embedded in web pages that are executed on the client-side (in the user’s web browser) rather than on the server-side. Cross-site scripting attacks, also known as XSS attacks, are one of the most common application-layer web attacks.
Brought about by the web security weaknesses of client-side scripting languages, such as HTML and JavaScript, XSS vulnerabilities permit an attacker to:
- Pretend to be the targeted user.
- Carry out any actions that the user is able to perform.
- Access any of the user’s data.
What is most dangerous is when the targeted user has privileged access within the web application. If so, then the attacker might be able to gain full control over all of the web application’s functionality and data.
When attackers exploit XSS vulnerabilities, they can perform malicious actions, such as:
- Hijack an account by gaining access to account credentials.
- Spread web worms.
- Access a user’s browser history and clipboard contents.
- Control a user’s browser remotely.
- Scan and exploit intranet appliances and applications.
How it works?
A target URL is the parameter to be scanned by the XSS Vulnerability Scanner. The tool needs the full URL of the target that includes http:// or https:// as the protocol. Since the tool does not follow any redirects, the exact URL will be scanned.
This tool runs a security check by replacing the original parameters of a test step with harmless strings, which resemble the malicious strings that are used in real attacks. It injects these strings to both XML elements and JSON fields.
The XSS scanner then uses assertions to validate requests and responses and check if they include any information about potential web application vulnerabilities. ‘PASS’ will be logged for all assertions that pass successfully. ‘FAIL’ will be logged for any assertion that fails.
