Microsoft Message Queuing (MSMQ) Remote Code Execution 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 during the execution of a specific operation that recurs in a low frequency on the target system. This might require an attacker to invest a significant amount of time to exploit the vulnerability if the race condition is not won.

How could an attacker exploit the vulnerability?
To exploit this vulnerability, an attacker would need to send a specially crafted malicious MSMQ packet to a MSMQ server. This could result in remote code execution on the server side.
