#Security Vulnerability

**How could an attacker exploit this vulnerability?** In a network-based attack, an attacker could trigger malicious code in the context of the server's account through a network call.

**According to the CVSS metrics, successful exploitation of this vulnerability could lead to major loss of confidentiality (C:H), integrity (I:H) and availability (A:H). What does that mean for this vulnerability?** An attacker who successfully exploited this vulnerability could access a user's Net-NTLMv2 hash which could be used as a basis of an NTLM Relay attack against another service to authenticate as the user.

**Is the Preview Pane an attack vector for this vulnerability?** No, the Preview Pane is not an attack vector.

**Is the Preview Pane an attack vector for this vulnerability?** No, the Preview Pane is not an attack vector.

**Is the Attachment Preview Pane an attack vector for this vulnerability?** Yes. The attachment Preview Pane that is accessed when a user clicks to preview an attached file is an attack vector; however, the email Preview Pane itself is not.

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** A domain user could use this vulnerability to elevate privileges to SYSTEM assigned integrity level.

**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 gather information specific to the environment of the targeted component.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of initialized or uninitialized memory in the process heap.
