Reflected XSS in a JavaScript URL with some characters blocked - Lab#28
In this video, I demonstrate how to exploit a Reflected Cross-Site Scripting (XSS) vulnerability in a JavaScript URL context, where some characters are blocked to prevent attacks. While the challenge appears straightforward, the application filters certain payloads, requiring a creative bypass. I successfully inject a payload that triggers an alert() function containing the string 1337. Watch till the end to see how I work around the restrictions!
🔹 Lab Type: Reflected XSS in JavaScript URL
🔹 Vulnerability: Character filtering in JavaScript URL context
🔹 Attack Goal: Execute alert() with "1337" in the message
