Description Preview

CVE-2023-24940 affects the Windows Pragmatic General Multicast (PGM) protocol implementation, which could allow an attacker to cause a denial of service condition. This vulnerability could potentially disrupt network services and communications that rely on the PGM protocol.

Overview

The Windows Pragmatic General Multicast (PGM) protocol implementation contains a vulnerability that could be exploited to cause a denial of service condition. PGM is a reliable multicast transport protocol designed for applications requiring ordered, duplicate-free, multicast data delivery from multiple sources to multiple receivers. When exploited, this vulnerability could allow an attacker to disrupt network services, potentially affecting system availability and performance. The attack vector likely involves sending specially crafted network packets to the targeted system.

Remediation

Users and administrators should apply the security updates provided by Microsoft as soon as possible. Microsoft has released patches addressing this vulnerability in their security updates. To remediate:

  1. Ensure systems are updated with the latest Microsoft security patches.
  2. Apply the specific security update referenced in the Microsoft Security Response Center (MSRC) advisory.
  3. If patching is not immediately possible, consider implementing network filtering to restrict access to PGM protocol traffic where feasible.
  4. Monitor systems for unusual network activity that might indicate exploitation attempts.
  5. Follow Microsoft's security best practices for network configuration and management.
