The Microsoft SQL Server installation on the remote host is missing a security update. It is, therefore, affected by an elevation of privilege vulnerability. An authenticated, remote attacker can exploit this issue, to gain elevated privileges.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
