XSS-Sniper is not included in Kali Linux, but is definitely worth trying. It is an open source tool by Gianluca Brindisi that can search for XSS vulnerabilities, including DOM-based XSS in a specific URL, or it can crawl an entire site. Although not as feature-rich as XSSer, it is a good option when XSSer is not available or to verify results.
XSS-Sniper can be downloaded from its GitHub repository:
git clone https://github.com/gbrindisi/xsssniper.git
To run a basic scan over a GET request, use only the -u parameter followed by the full URL including a test value:
python xsssniper.py -u http://10.7.7.5/bodgeit/search.jsp?q=test
Burp Suite Professional and OWASP ZAP include a vulnerability scan functionality that can detect many XSS instances with good accuracy. Scanners such as W3af, Skipfish, and Wapiti can also be used.
