Research on SQL Vulnerability Mining Based on Manual Operation

Although a large number of network security devices are deployed in the network and encryption protocols are used for communication, when users send data access requests to network servers, due to negligence in the development process of network application services and integration issues between different application software, web servers do not strictly review and filter the query statements sent by users, resulting in data leakage in the network database. This article introduces a new method of manually building query conditions from a security perspective to mine SQL vulnerabilities. This method can use different query conditions to detect vulnerabilities in web server-side review and filtering mechanisms. For the different vulnerabilities detected, corresponding review and filtering mechanisms are adopted on the network server side to compensate for the vulnerabilities caused by lax review and filtering on the network server side, thereby improving the security of data on the network.
