#Security 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.

**How could an attacker exploit this vulnerability?** In a network-based attack an attacker would need to have the privileges to query the Domain Name Service (DNS). If the timing of DNS queries is perfect, the attacker could execute code remotely on the target 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.

**How could an attacker exploit this vulnerability?** An authenticated attacker with normal privileges could send a modified XPS file to a shared printer, which can result in a remote code execution.

**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.

**How could an attacker exploit this vulnerability?** An authenticated attacker with normal privileges could send a modified XPS file to a shared printer, which can result in a remote code execution.

**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.

**How could an attacker successfully exploit this vulnerability?** An attacker could convince a user on the target device to open a maliciously crafted HTA file designed to appear as a legitimately signed WIM file (Windows Imaging Format).

**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 the vulnerability?** A domain user could use this vulnerability to elevate privileges to SYSTEM assigned integrity level.
