Cross-site scripting (XSS) is an example of a web security vulnerability.
Attacks inject malicious scripts into trusted websites and applications.
These scripts are intended to be executed by the victim when they visit the targeted website or application.
An attacker may entice a user to click on a malicious link, triggering an XSS attack.
XSS attacks exploit access restrictions like the same-origin policy, which separates websites from one another.
Caturls.txt is filtered to exclude common file types (jpg, jpeg, js, cs, gif, tiff, png, woff, woff2, ico, pdf, svg, txt) and replace quotation mark pairs with special characters used for XSS.
The script then fuzzes the injected characters in URLs and searches for potential vulnerabilities, printing vulnerable or not vulnerable accordingly.
This automated XSS detection script is useful for identifying potential security vulnerabilities in web applications and webpages.
Protecting web applications and maintaining online security requires constant vigilance and up-to-date security measures.
