"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 an sql command ('sql injection') in SQL Server allows an authorized attacker to elevate privileges over a network.
    (CVE-2026-47295)

  - Improper neutralization of special elements used in an sql command ('sql injection') in SQL Server allows an authorized attacker to elevate privileges locally.
    (CVE-2026-47296)

  - Buffer over-read in SQL Server allows an authorized attacker to disclose information over a network.
    (CVE-2026-50468)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
