I’m having issues finding what causes XSS vulnerabilities in my phpscript. it got rejected 2 times due to XSS vulnerabilities. and reviewer sent me just a small screen shot which contain an alert with xss. i have used Codeigniter framework and after 1st time it got soft rejected i made all the changes using codeigniter security functions to avoid these. After the full modification i resubmitted but it got rejected again due to the same reason. But i can’t find any vulnerabilities like that. can some one help me on this? is there any tool that i can use to scan my script? Because last time there were xss issues and i fixed them all, But now i almost spent more than 2 days and i couldn’t find find any issue.
Thanks in advance.
