Conclusion

MySQL is a popular open source relational database management system that is used by millions of websites around the world. It is one of the most popular choices for web developers to use when building a website, along with PostgreSQL and MongoDB. The main reason for its continued popularity is because of the quality and consistency of the software, which has been maintained by the same team of developers for the past 17 years.

The newly discovered security vulnerabilities listed in this article can be easily exploited by malicious attackers to gain unauthorized access to a MySQL server, resulting in

SQL Injection

SQL Injection vulnerabilities allow an attacker to inject malicious SQL queries into the MySQL database. When this happens, the user account that is logged in and has access permissions to the database will be given elevated privileges, which can lead to privilege escalation and eventual takeover of the entire MySQL server.

There is a new vulnerability called CVE-2018-3068, which allows a low privileged user to escalate privilege and gain access to the MySQL server.

InnoDB privilege escalation vulnerability

A low privileged user can escalate privilege and gain access to the MySQL server.

A low privileged user can escalate privilege and gain access to the MySQL server.

MySQL Database Security Weaknesses data theft, server instability, and possible denial of service. These security vulnerabilities can be exploited by malicious attackers without the need to use a complex SQL injection or cross-site scripting exploit.


The best way for website owners to protect their websites against these exploits is by using MySQL version 5.6 or later, which includes all of the updates in this article. Another option would be to upgrade to MySQL version 5.7 because it also includes critical fixes that were not included in MySQL versions 5.6 through 5.6.24 and 5.7 through 6.5 when vulnerabilities were discovered in those versions four years ago and one year ago, respectively.

MySQL Database Security Weakness

A database vulnerability (also called a SQL injection) is a weakness in the way software processes user input data, which can allow an attacker to bypass access controls or other security mechanisms.

This vulnerability can be exploited by supplying specially crafted input to certain MySQL queries. This vulnerability was identified by researchers at MWR Labs and Tencent Security Lab.
