Description

The Microsoft SQL Server installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:

 - Improper neutralization of special elements used in a command ('command injection') in SQL Server allows an unauthorized attacker to execute code over a network. (CVE-2026-116930)

 - Heap-based buffer overflow in SQL Server allows an unauthorized attacker to execute code over a network.
 (CVE-2026-116945, CVE-2026-118106)
