". For example: The user uses an aggressive URL as the input source. For example, , the server jumps to the corresponding error page, as shown below: In this way, malicious Js in www.xxx.com will be executed. Hackers can package or directly expose the URL of the submitted request. users usually see that the URL of a trusted website does not have any preventive clicks, resulting in losses, for example, the above can be exposed to the user URL: Http: // localhost: 8080/

. WebScarab is a proxy tool. It can intercept the communication process of the web browser and analyze the content so that you can easily modify it. For example, if I send a submit request, webScarab first intercepts the content and does not rush to the Real Server. Instead, a window pops up to allow you to modify the content. After the modification is completed, it is submitted to the server. If some restrictions are imposed on the webpage input box, for example, the length limit and Number For

There are two ways to bypass front-end verification: First, debug using developer tools, and second, using Burpsuite to crawl directly.

EXP9 the basic practice of Web security Fundamentals Answer 1, SQL injection attack principle, how to defend?1.对用户的输入进行校验，可以通过正则表达式，双"-"进行转换等。2.不要使用动态拼装sql，可以使用参数化的sql或者直接使用存储过程进行数据查询存取。3.不要使用管理员权限的数据库连接，为每个应用使用单独的权限有限的数据库连接。4.不要把机密信息直接存放，加密或者hash掉密码和敏感的信息。5.应用的异常信息应该给出尽可能少的提示。6.采取辅助软件或网站平台来检测sql注入。2, how to defend the principle of XSS attack?在表单提交或者url参数传递前，对需要的参数进行过滤；检查用户输入的内容中是否有非法内容，如尖括号、引号等，严格控制输出。3, CSRF attack principle, how to defend?通过referer、token或者验证码来检测用户提交；尽量不要在页面的链接中暴露用户隐私信息，对于用户修改

I hope that through this experiment, I will learn about the basic vulnerabilities in web security, as well as the basic exploit techniques.Of course, the basic knowledge must be filled, after the learning process should be short of what to fill.

any PC that can connect to the Internet, and do some damage in the identity of others. Defense: Filter the required parameters before the form submission or URL parameters are passed, and check the contents of user input for illegal content, such as angle brackets, quotation marks, etc., and strictly control the output. (3) CSRF attack principle, how to defend? CSRF attack is a cross-site forgery attack, as the name implies, is an attacker to the target site to inject a malici

because the request is not intended by the user, so it is called "cross-site request forgery".Defensive measures:① through Referer, token or verification code to detect user submissions;② try not to expose the user's privacy information in the link of the page, and it is best to use post operation for the user to modify and delete the operation;③ avoids the whole-site generic cookie and strictly sets the domain of the cookie.Second, the experimental process 1.
