James Forshaw, a security researcher with Google's Project Zero security initiative, stated that the privilege escalation vulnerability could be exploited due to the way the operating system handles calls to Advanced Local Procedure Call (ALPC).
This implies that standard users could obtain Admin privileges on Windows 10 computers. In the event of an attack, the attacker could gain full control over the affected system.
However, Neowin notes that this is the second issue discovered in the same feature, both marked as bugs 1427 and 1428, reported by Microsoft on 10/11/2017. Microsoft stated they addressed these issues in the Patch Tuesday update released in February 2018, although only bug 1427 was resolved.

Not remotely exploitable
Although the vulnerability remains unpatched, and Microsoft does not consider it severe. According to researchers, this vulnerability's exploitability is related to additional steps and cannot be executed remotely unless the attacker has previously accessed target systems by exploiting other vulnerabilities.
'To exploit, you must execute code on the system at the normal user privilege level. Remote attacks are not possible (not exploiting an entire vulnerability to execute code remotely) and sandboxing, as used in Edge and Chrome browsers, cannot be utilized,' according to Forshaw.

The next Windows security update will be released on March 13th, as part of the Patch Tuesday cycle. However, following Google's disclosure of the vulnerability in Windows 10 Fall Creators Update with the exploitability disclosed, Microsoft may quickly release patches for affected Windows versions sooner.
