Microsoft’s ODBC Driver for SQL Server was found to contain a remote code execution vulnerability. The ODBC (Open Database Connectivity) Driver is a software component that allows applications to connect and interact with SQL Server databases.

Attackers could exploit this vulnerability (tracked as CVE-2023-21704) to execute arbitrary code on systems where the vulnerable ODBC driver is installed. All they need is a way to communicate with the target system over the network. No user interaction would be required.

The vulnerability receives a CVSS score of 7.8, making it a serious risk. Attackers could potentially install programs, view, change or delete data, or create new accounts with full user rights on affected systems.

If you use SQL Server databases, make sure to update your ODBC driver software to the latest version released by Microsoft. This will protect against attacks targeting the vulnerability. It’s also recommended to apply the principle of least privilege and restrict network access to SQL Server instances as much as possible.

Keeping all software on your computers updated is one of the best ways to stay protected. Configure automatic updates if possible so you don’t miss any security patches. Staying on top of software updates is crucial for your security in today’s threat landscape.
