**How could an attacker exploit this vulnerability?** An unauthenticated attacker could exploit the vulnerability by sending a specially crafted request to a Windows Server configured as a Layer-2 Bridge.

This vulnerability is only exploitable on Windows Servers that have installed and configured the Routing and Remote Access Service (RRAS) role which is not installed and configured by default. Please see Routing and Remote Access Server (RRAS) | Microsoft Learn for more information.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** The user would have to click on a specially crafted URL to be compromised by the attacker.

**According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?** Within a SharePoint site, the attacker must be authenticated, and they would need to have the “Use Remote Interfaces” and “Add and Customize Pages” permissions on a Policy Center site to be able to exploit this vulnerability.

**How could an attacker exploit the vulnerability?** In a network-based attack, an authenticated attacker with Manage List permissions could execute code remotely on the SharePoint Server.

**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, user interaction is required (UI:R). What interaction would the user have to do?** The user would have to click on a specially crafted URL to be compromised by the attacker.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** The user would have to click on a specially crafted URL to be compromised by the attacker.

**According to the CVSS metric, successful exploitation of this vulnerability could lead to some loss of integrity (I:L)? What does that mean for this vulnerability?** The attacker who successfully exploits the vulnerability could download files without the access being logged.
