The agent in Microsoft SQL Server 2012 SP2, 2012 SP3, 2014 SP1, 2014 SP2, and 2016 does not properly check the atxcore.dll ACL, which allows remote authenticated users to gain privileges via unspecified vectors, aka "SQL Server Agent Elevation of Privilege Vulnerability."

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)

The remote host is running a version of Microsoft SQL Server 2012 SP3 11.0.6020.0 through 11.0.6247.0 and is affected by multiple privilege escalation vulnerabilities :

 - A flaw exists in the SQL Server Agent that is triggered as ACLs on 'atxcore.dll' are not properly checked. This may allow an authenticated attacker to gain elevated privileges. (CVE-2016-7253)
 - A flaw exsts in the RDBMS engine that is triggered during the handling of pointer casting. This may allow an authenticated attacker to gain elevated privileges. (CVE-2016-7254)

The remote host is running a version of Microsoft SQL Server 2012 SP2 11.0.5058.0 through 11.0.5387.0 and is affected by multiple privilege escalation vulnerabilities :

 - A flaw exists in the SQL Server Agent that is triggered as ACLs on 'atxcore.dll' are not properly checked. This may allow an authenticated attacker to gain elevated privileges. (CVE-2016-7253)
 - A flaw exsts in the RDBMS engine that is triggered during the handling of pointer casting. This may allow an authenticated attacker to gain elevated privileges. (CVE-2016-7254)
