is a security vulnerability in Web applications. Attackers can exploit this vulnerability to submit malicious data to applications and cheat applications in executing malicious SQL commands on servers. Theoretically, this type of attack is easy to prevent. However, because it allows attackers to directly run database commands targeting users' key data, it becomes a common and harmful form of attack. In ext

We should all know that SQL is the first web vulnerability. No matter which language is used for web backend development, as long as a relational database is used, SQL
Label:in the previous blog we analyzed the principle of SQL injection, today we look at the overall process of SQL injection, that is, how to do SQL injection, because I have limited knowledge of database and network , this articl
In those years, we will explore the global protection of SQL Injection Bypass wide byte injection.0x01 background
First, let's take a look at the wide byte injection. The wide byte injection is caused by the error set: set character_set_client = gbk when the programmer sets
1. The magic_quotes_gpc option in the php. ini configuration file of the php tutorial is not enabled and is set to off. 2. The developer does not check and escape the data type.
But in fact, the second point is the most important. In my opinion, it should be the most basic quality for a web programmer to check the data types entered by users and submit the correct data types to the mysql tutorial. But in reality, many small web developers often forget this, leading to a wide open backdoor.

SQL Injection and anti-injection are actually attacks and defenses. Today we want to tell you the most basic injection and prevention methods, the principle is caused by the use of some features of php or mysql.

After reading the introductory and advanced chapter, a little practice, crack the general website is no problem. But if you hit the list name, or the program author filters some special characters, how to improve the success rate of injection? How to improve the efficiency of guessing? Please keep looking at the advanced article.
Section one, using system tables to inject SQL Server data
IntroductionWith the development of B/s pattern application development, more and more programmers use this pattern to write applications. But because the entry threshold of the industry is not high, the level of programmers and experience is uneven, a large number of programmers in the code, not the user input data to judge the legality, so that the application has security problems. Users can submit a database query code, based on the results returned by the program to obtain some of the data
1. The MAGIC_QUOTES_GPC option in the PHP tutorial configuration file php.ini is not turned on and is set to off 2. The developer did not check and escape the data type
But in fact, the 2nd is the most important. I think that it is the most basic quality of a web programmer to check the data type entered by the user and submit the correct data type to the MySQL tutorial. But in reality, many small white web developers often forget this, leading to a backdoor opening.
