Summary

Microsoft SQL Server 2008 SP3 and SP4, 2008 R2 SP2 and SP3, 2012 SP1 and SP2, and 2014 uses an incorrect class during casts of unspecified pointers, which allows remote authenticated users to gain privileges by leveraging certain write access, aka "SQL Server Elevation of Privilege Vulnerability."

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Embedding Scripts within Scripts
    An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
  • Signature Spoofing by Key Theft
    An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

    descriptionThe remote Microsoft SQL Server installation is affected by multiple vulnerabilities : - A privilege escalation vulnerability exists due to the casting of pointers to an incorrect class. An authenticated, remote attacker can exploit this, via a specially crafted SQL query, to gain elevated privileges. (CVE-2015-1761) - A remote code execution vulnerability exists due to incorrect handling of internal function calls to uninitialized memory. An attacker can exploit this, via a specially crafted SQL query on an affected SQL server that has special permission settings (such as VIEW SERVER STATE) turned on, to execute arbitrary code. (CVE-2015-1762) - A remote code execution vulnerability exists due to incorrect handling of internal function calls to uninitialized memory. An authenticated, remote attacker can exploit this, via a specially crafted SQL query designed to execute a virtual function from a wrong address, to execute arbitrary code. (CVE-2015-1762)
