FAQ: Why is Attack Complexity marked as High for this vulnerability?
A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in execution against the vulnerable component before a successful attack can be expected. For this vulnerability, a successful exploitation requires an attacker to win a race condition.

[HIGH] Microsoft Patch Tuesday, August 2022 Edition
Microsoft today released updates to fix a record 141 security vulnerabilities in its Windows operating systems and related software. Once again, Microsoft is patching a zero-day vulnerability in the Microsoft Support Diagnostics Tool (MSDT), a service built into Windows. Redmond also addressed multiple flaws in Exchange Server — including one that was disclosed publicly prior to today — and it is urging organizations that use Exchange for email to update as soon as possible and to enable additional protections.
In June, Microsoft patched a vulnerability in MSDT dubbed “Follina” that had been used in active attacks for at least three months prior. This latest MSDT bug — CVE-2022-34713 — is a remote code execution flaw that requires convincing a target to open a booby-trapped file, such as
