#Security Vulnerability

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** This vulnerability could lead to a browser sandbox escape.

**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.

**Why is this Intel CVE included in the Security Update Guide?** The vulnerability assigned to this CVE is in certain processor models offered by Intel. The mitigation for this vulnerability requires a firmware update, and a corresponding Windows updates enables the mitigation. This CVE is being documented in the Security Update Guide to announce that the latest builds of Windows enable the mitigation and are not vulnerable to the issue when paired with the firmware update. Please see the following for more information: https://www.intel.com/content/www/us/en/developer/articles/technical/softwaresecurity-guidance/advisory-guidance/register-file-data-sampling.html

**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 file content.

**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 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 the contents of Kernel memory. An attacker could read the contents of Kernel memory from a user mode process.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is information disclosure?** The attack itself is carried out locally. For example, when the score indicates that the **Attack Vector** is **Local** (AV:L) and **User Interaction** is **Required** (UI:R), this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and run a malicious application. This could lead to a local attack on the user's device which could leak data.

**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 the vulnerability?** An attacker would only be able to delete targeted files on a system. They would not gain privileges to view or modify file contents.

**According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?** An authenticated victim who is connected to the network must be tricked or persuaded to connect to a malicious SQL database using their SQL client application. After the connection is made, the server can send specially crafted replies to the client that exploit the vulnerability and permit execution of arbitrary code within the context of the user's SQL client application.
