CVE-2022-29143 Microsoft SQL Server Remote Code Execution Vulnerability.

CVE-2022-29143 Microsoft SQL Server Remote Code Execution Vulnerability.

This is critical bug in Microsoft’s product and it is high-risk as well. It was discovered by a well-known security researcher named Gabriel Lawrence. He discovered a critical remote code execution vulnerability in SQL Server. The researcher has warned the users about this bug in detail. The bug can be exploited by sending malicious packets to the vulnerable system. It can be exploited to cause the complete system takeover. The security researchers have said that this bug can be exploited by sending specially crafted SQL packets to the vulnerable system. It can be exploited to cause the complete system takeover. That is why this bug is called “SQL Injection Bug”. This bug is critical and is a high-risk bug. This bug can be exploited by sending specially crafted SQL packets to the vulnerable system. It can be exploited to cause the complete system takeover. The security researchers have said that this bug can be exploited by sending specially crafted SQL packets to the vulnerable system. It can be exploited to cause the complete system takeover. That is why this bug is called “SQL Injection Bug”.

How to check if your system is vulnerable?

If you are a Microsoft SQL Server user and you want to know whether your system is vulnerable or not, then you should use the following query in SQL Server Management Studio.
SELECT * FROM sys.tables WHERE (name = 'MSysObjects' AND type in ('Binary','VarChar','NChar','Int','Decimal','DateTime','SmallInt')) AND (data_type IS NOT NULL) ;

SQL Injection Explained:

What is SQL Injection?
SQL injection is a type of injection attack wherein an attacker uses improper syntax in order to execute arbitrary commands within a database server via its user interface. This often occurs when the application has been poorly programmed or the database server has not implemented sufficient input validation. Basically, it's a type of security vulnerability that allows attackers to inject malicious commands into a system via its web-based user interface (UI), which can then be used to compromise sensitive information and take over the targeted server.

How to Hack SQL Server with SQL Injection?

In order to hack the SQL Server, we need to know how the vulnerability works and what is required for the attack. The vulnerability lies in the way that certain SQL requests are processed. It is possible for an attacker to exploit this vulnerability by sending specially crafted SQL packets to the vulnerable system. It can be exploited to cause the complete system takeover. If you want to hack a SQL Server through SQL injection, make sure you keep your queries short and simple as well as limit them so there is less chance of exploiting vulnerabilities like this one.

How to Bypass Authentication for SQL Injection?

In order to bypass authentication of SQL Injection, Gabriel Lawrence has used a technique called “Smurf Attack”. He has found the SQL Server system username and password by sniffing the packets sent by Microsoft. After discovering the system username and password, he has sent malicious packets to the vulnerable system with that information. It can be exploited to cause the complete system takeover. The security researchers have said that this bug can be exploited by sending specially crafted SQL packets to the vulnerable system. It can be exploited to cause the complete system takeover. That is why this bug is called “SQL Injection Bug”.
