Script-based XSS vulnerability detection

摘要

Detection of dynamic URLs that are vulnerable to XSS attacks is described. First, a dynamic URL is crafted by incorporating a piece of test code designed to expose an instance of XSS vulnerabilities. Next, the crafted URL is loaded into a browser, which causes a web page to be generated that may include the piece of test code. If, upon loading the web page into the browser, the piece of test code is executed by the browser and the browser sends a request to a web server as a result, then the URL is reported as XSS vulnerable. Others, the URL is not vulnerable to this instance of XSS attack. The test may be repeated multiple times for different pieces of test code, each piece designed to expose a different instance of XSS vulnerabilities.
