CVE-2022-23294: Windows Event Tracing Remote Code Execution Vulnerability

According to the score, privileges required is equal to low. In this situation, what does that mean?

An attacker with non-admin credentials can potentially carry out an exploit using this vulnerability.

How can an attacker exploit this vulnerability?

The authenticated attacker could potentially take advantage of this vulnerability to execute malicious code through the Event Log’s Remote Procedure Call (RPC) endpoint on the server-side.

What is a Remote Procedure Call (RPC)?

RPC is a communication mechanism that allows computers to communicate with one another over a network. An RPC consists of a procedure identifier, parameters passed to the procedure, and a value returned to the caller (client computer) after the procedure has executed on the remote system (server computer).

Are there mitigating factors related to this vulnerability?

Yes. Access to the Event Log service endpoint is blocked by default and a firewall rule change is required to make the endpoint accessible from a locally triggered attack.
