Embodiment 1

[0023] figure 1 A flowchart of a method for detecting an interactive XSS vulnerability provided by the first embodiment of the present invention is shown, and the details are as follows:

[0024] Step S11, send the detection request with the feature value constructed to the Web server, and receive the response page returned by the Web server;

[0025] In this step, the XSS detection tool receives and saves the http request sent by the client to the web server, and constructs a feature value according to the http request; specifically, based on the received and saved user http request, each http request is modified one by one The parameter value is modified into the characteristic value. The characteristic value is a string, and its purpose is to attempt XSS injection attack. For example, an eigenvalue could be: , if there is no XSS encoding protection on the page, the div will be inserted into the DOM structure as a DOM node. In addition, for different page output points,...

Abstract

The invention is suitable for the field of Web program applications, and provides a detection method and system for interactive XSS (Cross-Site Scripting) vulnerability. The method comprises the following steps that: sending a constructed detection request with a feature value to a Web server, and receiving a response page returned from the Web server; analyzing a DOM (Document Object Model) monitor injected into the response page in advance, then, analyzing an intelligent event simulator injected to the response page in advance, and finding and automatically triggering the event on a DOM structure of the response page through the intelligent event simulator; and according to the monitoring result of the DOM monitor, judging whether the XSS vulnerability is in the presence or not. Through the above method, through the execution of the intelligent event simulator, an effect on identifying and simulating user interaction is achieved, and therefore, an XSS detection tool obtains an integral DOM structure. Through the DOM monitor, the real-time monitoring of the DOM structure change situation of the response page is realized so as to realize the successful detection of the interactive XSS vulnerability of the response page.

Description

technical field [0001] The embodiments of the invention belong to the field of web program application, and in particular relate to a method and a system for detecting an interactive XSS vulnerability. Background technique [0002] With the widespread use of web applications, web security issues have become increasingly prominent. Cross-site scripting (XSS) is an attack by an attacker injecting a specific script into a page of a web application. When a user browses the page, the attacker The injected script will be executed to achieve the purpose of the attack. XSS has become one of the most common vulnerabilities in web applications, and automatic detection of XSS vulnerabilities has also become an important technology. With the development of Web 2.0 technology, the pages of Web applications can not only display static content, but also have more and more interactive functions with users. These interactive functions are often implemented by embedding JavaScript and CSS sc...
