**According to the CVSS metric, privileges required is high (PR:H). What does that mean for this vulnerability?** To successfully exploit this vulnerability, an attacker or the targeted user would need to achieve a high level of control over a machine, as the attack requires access to processes typically restricted from average users. Essentially, the exploitation necessitates elevated privileges on the compromised machine due to the requirement of manipulating processes beyond the reach of standard user permissions.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.

**According to the CVSS metrics, successful exploitation of this vulnerability could lead to major loss of confidentiality (C:H), integrity (I:H), and availability (A:H). What does that mean for this vulnerability?** An attacker who successfully exploited this vulnerability could gain high privileges, which include read, write, and delete functionality.

**Is the Preview Pane an attack vector for this vulnerability?** No, the Preview Pane is not an attack vector.

**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 gather information specific to the environment and take additional actions prior to exploitation to prepare the target environment.

**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.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is data inside the targeted website like IDs, tokens, cryptographic nonces, and other sensitive information.

**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, 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.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.
