**According to the CVSS metrics, successful exploitation of this vulnerability could lead to no loss of confidentiality (C:N), some loss of integrity (I:L) but have no effect on availability (A:N). What is the impact of this vulnerability?** An attacker could spoof incorrect **5322.From** email address that is displayed to a user.

Improper handling of additional special element in Microsoft Exchange Server allows an unauthorized attacker to perform spoofing over a network.

**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.
