XSS vulnerability search and detection
1. Black box testing
Black box testing refers to testing the system without knowing the code and running status of the system. In the detection of XSS vulnerabilities, we can simulate hacker attack methods and try to inject some XSS at all possible data input interfaces. Observe the page that references the data after the in
a long time to discover the problem. For example, not long ago, we posted the XSS worm script, which was not known until it was reported by users after the outbreak of a large scale. The majority of other websites are similar. vendors are not notified until white hats discover vulnerabilities and submit them to the security platform. If hackers keep these vulnerabilities in private and take advantage of th
