Detection Guidance

This vulnerability can be detected by testing the user creation process for improper input sanitization, specifically by injecting typical XSS payloads such as `<img src onerror="prompt(8)">` into the 'your_name' parameter and observing if the script executes when visiting the users page. There are no specific commands provided, but manual testing or using web vulnerability scanners targeting the user creation page (e.g., https://webigniter.net/create-account) with XSS payloads can help detect the issue.

Mitigation Strategies

Immediate mitigation steps include implementing strict input validation and encoding on the 'your_name' parameter in the user creation process to ensure all user inputs are sanitized and rendered safe, preventing the execution of malicious scripts. Additionally, restricting or escaping special characters in user inputs can help prevent XSS attacks. [2]
