Problems solved by technology

Most of the existing web application model derivation methods for XSS vulnerability detection are based on the traditional finite state machine model. The model does not include navigation information, which is insufficient in the expression ability of web application functions, and there are many redundant information.

Abstract

The invention discloses a web application reverse analysis method oriented to XSS (Cross Site Scripting) vulnerability detection. A microscopic state is added into a Web application model to express a navigation relationship in the Web application; in a Web application model deduction process, a state change detection algorithm and a navigation function are adopted to finish initial Web application model construction; a page clustering algorithm and a state reduction algorithm are adopted to simplify the Web application model; and finally, an experiment proves that the model is favorable for improving the effect and the efficiency of the XSS vulnerability detection. According to the method, an existing Web application model is improved, the concept of the microscopic state is added, a hierarchical Web application model representing method is put forward, so that the hierarchical Web application model representing method can describe a transition relationship between Web application states, and the navigation relationship in the Web application can be presented.

Description

technical field [0001] The invention relates to an automatic reverse analysis method of a Web application model oriented to XSS loophole detection, and belongs to the field of computer information security. Background technique [0002] With the continuous growth of Internet users and the number of websites, Web applications have been widely used in various fields, such as e-commerce, social networking, and online payment. In 2015, the total number of domain names in my country reached 31.02 million. At the same time, the security issues of Web application systems are becoming more and more prominent. According to the statistics of the China Vulnerability Database, in 2015, among the security vulnerabilities included in the China Vulnerability Database, the number of web application vulnerabilities ranked second. Among them, the XSS vulnerability is one of the most influential web application vulnerabilities, ranking among the top three in the latest ranking of web applica...
