Risk summary
Senserva AI Opinion for CVE-2024-43459
Like the other Native Client CVEs patched with it, this High Severity CVSS 8.8 flaw allows code execution through the SQL Server client driver on SQL Server 2016 SP3, 2017, and 2019. The realistic attack path is a connection to an attacker-controlled database server, so systems that make outbound SQL connections to untrusted destinations carry the risk. EPSS holds at 2 percent.
Do this: Restrict outbound SQL connections from servers to known database hosts while the GDR updates roll out.
