**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** An attacker must send the user a malicious file and convince the user to open said file.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** An attacker must send the user a malicious file and convince the user to open said file.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited this vulnerability could execute RPC procedures that are restricted to privileged accounts, bypassing the access check for the RPC procedures.

**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 take additional actions prior to exploitation to prepare the target environment.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of this vulnerability requires that a user trigger the payload in the application.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of this vulnerability requires that a user trigger the payload in the application.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of the vulnerability requires that a user open a specially crafted file. * In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. * In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited this vulnerability could execute RPC procedures that are restricted to privileged accounts, bypassing the access check for the RPC procedures.

**According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?** The attacker must be authenticated to the target site, with the permission to use Manage Lists within SharePoint.
