The remote Microsoft SQL Server is missing a security update. It is, therefore, affected by multiple vulnerabilities :
Multiple elevation of privilege vulnerabilities exist in the SQL RDBMS Engine due to improper handling of pointer casting. An authenticated, remote attacker can exploit these to gain elevated privileges.
(CVE-2016-7249, CVE-2016-7250, CVE-2016-7254)
A cross-site scripting (XSS) vulnerability exists in the SQL server MDS API due to improper validation of a request parameter on the SQL server site. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary code in the user’s browser session. (CVE-2016-7251)
An information disclosure vulnerability exists in Microsoft SQL Analysis Services due to improper validation of the FILESTREAM path. An authenticated, remote attacker can exploit this to disclose sensitive database and file information. (CVE-2016-7252)
An elevation of privilege vulnerability exists in the Microsoft SQL Server Engine due to improper checking by the SQL Server Agent of ACLs on atxcore.dll. An authenticated, remote attacker can exploit this to gain elevated privileges. (CVE-2016-7253)
