Windows ALPC Elevation of Privilege Vulnerability
Actively exploited in the wild. Patch or mitigate immediately — don't wait for a maintenance window.
An attacker with a basic user account, with local access to the host, with no user interaction, can fully compromise the system — steal data, tamper with it and take it offline.

Generated by Wavense from the CVE record — an immediate mitigation and the permanent fix.
To reduce risk before patching, enforce the principle of least privilege, ensuring users only have necessary permissions and local administrative rights are strictly controlled. Deploy and monitor robust Endpoint Detection and Response (EDR) solutions to detect anomalous process behavior or suspicious privilege escalation attempts. Consider implementing application whitelisting to prevent unauthorized code execution on endpoints.
The permanent resolution involves applying the security updates released by Microsoft that address CVE-2023-21674. Organizations should prioritize patching all affected Windows client and server operating systems according to Microsoft's official guidance. Verify successful patch deployment across the environment to fully remediate this elevation of privilege vulnerability.
An attacker who successfully exploits this vulnerability could elevate their privileges from a standard user to SYSTEM. This grants the attacker full administrative control over the compromised system, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights. The business consequences include potential data breaches, system compromise, and significant operational disruption.
