Knowledge vulnerabilities are not terrible. What is terrible is human vulnerabilities. Today, I once again showed the vulnerability. It is actually about MVC. I thought I had learned the design pattern and explored its connotation. Therefore, it is entirely wishful thinking to understand MVC. Ah, it hurts. Fortunately, our teacher asked me to talk to me about this matter tonight. Otherwise, I guess I (we)

Identifies network security threats and vulnerabilities and Network Security Vulnerabilities 1. Social engineering attacks are an attack type that uses deception and tricks to persuade uninformed users to provide sensitive information or conduct behaviors against security rules.

Title: Common Vulnerabilities in php programs and how to mine VulnerabilitiesAuthor: Xiao DanThe article I wrote for you is mainly about some penetration experience related to simple vulnerability mining in php.1. File writing VulnerabilityOne of the first types of analysis is the file writing vulnerability. I remember that many programs died on this vulnerability.$ File = .... /Then a defined variable name/info. php.Php and asp are different. Some as

is popular. At that time, almost all Websites stored on the website had vulnerabilities. At the moment, many platforms have disabled storage. In fact, the root cause is this. We get the file name and save it as the final generated file name. A good way is to randomly generate a file name + read extension. In this way, special characters can be entered, which are discarded or truncated during file storage. This vulnerability can be exploited in the ph

These vulnerabilities are not only for PHP, but also for how PHP effectively prevents them. 1. XSS + SQL injection (detailed introduction to XSS attacks) XSS

Common PHP vulnerabilities: Injection Vulnerability injection brings controllable user variables into database operations and changes the original SQL intention. For example, in the logic of registering a user, when detecting whether the user name exists, you can retrieve the user name submitted by the user to the database for query.

Do web development, we often do code to check, many times, we will spot some core functions, or often the logic of vulnerabilities. With the expansion of the technical team, the group's technology is increasingly mature. Common fool-type SQL injection vulnerabilities, and XSS vulnerabilities. will be fewer and less, but we will also find that some of the emerging
