  • Patent number: 9021593
    Abstract: The present invention discloses a XSS detection method for detecting the XSS vulnerabilities in a web page, comprising for each parameter-value pair in a set of parameter-value pairs that can be accepted by the web page: constructing a parameter-value pair in which a dedicated script is inserted; assembling a URL corresponding to the web page based on the parameter-value pair in which a dedicated script is inserted; acquiring the dynamic web page content corresponding to the assembled URL; and simulating the execution of the acquired dynamic web page content, if the dedicated script is executed, it is determined that the processing of the parameter in the web page contains XSS vulnerabilities. The present invention further discloses a corresponding XSS detection device and a web site security scanning system and a web scanning system using such a device.
