#Security Vulnerability

**According to the CVSS metric, successful exploitation of this vulnerability could lead to total loss of confidentiality (C:H), integrity (I:H), and availability (A:H). What does that mean for this vulnerability?** An attacker who successfully exploits this vulnerability could perform a remote attack that could enable access to the victim's information and the ability to alter information. Successful exploitation could also potentially cause downtime for the targeted environment.

**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?** An attacker must send the user a malicious file and convince them to open it.

**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.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**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.

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

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** The vulnerability is in the web server, but the malicious scripts execute in the victim’s browser on their machine.
