**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.

**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 win a race condition.

**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.

The following mitigation may be helpful in your situation. In all cases, Microsoft strongly recommends that you install the updates for this vulnerability as soon as possible even if you plan to leave Remote Desktop Licensing Service disabled: **1\. Disable Remote Desktop Licensing Service if is not required.** If you no longer need this service on your system, consider disabling it as a security best practice. Disabling unused and unneeded services helps reduce your exposure to security vulnerabilities.

**How could an attacker exploit this vulnerability?** An attacker could send a specially crafted packet to a server set up as a Remote Desktop Licensing server, which will cause remote code execution.

**According to the CVSS score, the attack vector is adjacent (AV:A). What does this mean for this vulnerability?** This attack is limited to systems connected to the same network segment as the attacker. The attack cannot be performed across multiple networks (for example, a WAN) and would be limited to systems on the same network switch or virtual network.

**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?** 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 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.

**According to the CVSS metric, privileges required is high (PR:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires the attacker or targeted user to have specific elevated DHCP Server privileges. As is best practice, regular validation and audits of administrative groups should be conducted.
