**According to the CVSS metric, user interaction is required (UI:R) and privileges required is low (PR:L). What does that mean for this vulnerability?** An authorized attacker must be on the network to monitor domain network traffic (PR:L) while monitoring for user (UI:R) generated network traffic, or alternatively that attacker convinces an authenticated user to execute a malicious script, as a step to exploit this vulnerability.

**According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability?** An authenticated attacker could exploit this vulnerability with LAN access.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to possess advanced reverse engineering skills to identify and gain unauthorized access to specific remote procedure call (RPC) endpoints.

**According to the CVSS metric, privileges required is low (PR:H). What does that mean for this vulnerability?** An authenticated attacker with Site Owner permissions can use the vulnerability to inject arbitrary code and execute this code in the context of SharePoint Server.

**How could an attacker exploit this vulnerability?** To exploit this vulnerability, a victim machine must be running a performance counter collection tool such as Performance Monitor to collect performance counter data from an attacker machine. An attacker with local admin authority on the attacker machine could run malicious code remotely in the victim machine's performance counter data collector process.

**According to the CVSS metric, user interaction is required (UI:R) and privileges required  is low (PR:L). What does that mean for this vulnerability?** An authorized attacker with standard user privileges could place a malicious file and then wait for the privileged victim to run the calling command.

**According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability?** An authenticated attacker could exploit this vulnerability with LAN access.

**According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability?** An unauthenticated attacker with LAN access could exploit this vulnerability.

**How could an attacker exploit this vulnerability?** An attacker could exploit the vulnerability by tricking an authenticated user (UI:R) into attempting to connect to a malicious SQL server database via a connection driver (for example: OLE DB or OLEDB as applicable). This could result in the database returning malicious data that could cause arbitrary code execution on the client.
