#Security Vulnerability

**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.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could elevate their user privileges from those of a restrained user to an unrestrained WDAC user.

**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 one byte of kernel memory could be leaked back to the attacker.

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

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of certain kernel memory content.

**How could an attacker exploit this vulnerability?** An authenticated attacker could exploit the vulnerability by uploading a malicious TIFF file to a server.

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

**How could an attacker exploit the vulnerability?** An authenticated attacker with Site Owner permissions or higher could upload a specially crafted file to the targeted SharePoint Server and craft specialized API requests to trigger deserialization of file's parameters. This would enable the attacker to perform remote code execution in the context of 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.
