Microsoft SQL Server is a popular database management system used by many organizations worldwide. Unfortunately, researchers recently discovered a remote code execution vulnerability in one of its components called the WDAC OLE DB provider.

The WDAC OLE DB provider is a data access component that allows applications to connect and interact with SQL Server databases. Attackers could exploit this vulnerability by sending specially crafted requests that could allow them to run malicious code directly on the targeted server.

This vulnerability receives a CVSS score of 8.8 out of 10, meaning it is relatively easy to exploit and can allow an attacker to completely take over the server. They would then be able to access, modify or delete any data within the SQL Server databases. Servers with this component installed would be vulnerable even without direct internet access if another compromised system on the internal network was used as a stepping stone.

The best way for SQL Server administrators to protect themselves is to apply the security patch released by Microsoft to fix this issue. It is also recommended to carefully review your server access policies and network security controls. Making sure only authorized applications and users can access SQL Server databases can help reduce risks from remote exploits. Staying on top of the latest updates is crucial as new vulnerabilities are often discovered.
