A hacker can inject a SQL query to change the content of the database and steal critical information or even take over the system. A hacker can use this to change the information in the system to give him access to other people’s records, steal money from the system, etc. This can also be used to change the information in order to give access to other people’s records, steal money from the system, etc. This is a critical weakness as it can be exploited by hackers to cause significant damage to an organization. The weakness exists in the /diagnostic/editcategory.php?id= parameter. Hackers can inject SQL code to change the information in the database in order to cause significant damage to an organization.

Products Affected by CVE-2022-42074

- MySQL 5.1.73 and earlier, MySQL 5.5.29 and earlier, MariaDB 10.0.13 and earlier, Percona Server 5.5.51 and earlier

- MySQL Connector/J 5.1.73 and earlier, MySQL Connector/J 6.3 and later

SQL Injection and How to Find it?

There are few methods to find out whether there is a SQL injection vulnerability. One method is using the PHP function eval(). If you use this function in your code, if it has been tampered with, then it may be vulnerable to SQL injection.
Another method is using a JavaScript debugger. In this case, you can use a JavaScript debugger and reproduce the vulnerability on your own computer. This method will require you to have a copy of the code at hand that contains the vulnerability in order to reproduce it on your own machine. An additional feature of this method is that you can run the code on someone else's machine. A third method would be to use an automated tool such as Wapiti that can scan for and detect potential vulnerabilities in your system as soon as they are found.
The weakness exists in the /diagnostic/editcategory.php?id= parameter which grants access to other people's records and information in addition to your own records and information.

Summary of Key Results -

- A hacker can inject a SQL query to change the content of the database and steal critical information or even take over the system.
- This can also be used to change the information in order to give access to other people’s records, steal money from the system, etc.
- The weakness exists in the /diagnostic/editcategory.php?id= parameter. Hackers can inject SQL code to change the information in the database in order to cause significant damage to an organization.

SQL Injection and How to Avoid it

SQL injection is a type of software vulnerability that occurs when user input is improperly sanitized or validated. When this happens, an attacker can inject code into the SQL query used to retrieve information from the database, which results in unintended and potentially harmful effects on the database. The weakness exists in the /diagnostic/editcategory.php?id= parameter. Hackers can inject SQL code to change the information in the database.
The vulnerability exists because users are not required to enter any username or password for editing on a category page; they only need to enter their ID numbers (e.g., 1 for a first-level admin) for access to edit other users' records. However, a hacker may also use this by submitting SQL queries with malicious code that takes advantage of this input data validation error. It is important that organizations be aware of how hackers can exploit vulnerabilities like these and take precautions against them.
