CVE-2024-49122: 
vulnerability analysis and mitigation

Microsoft Message Queuing (MSMQ) Remote Code Execution Vulnerability (CVE-2024-49122) is a critical security flaw discovered and disclosed in December 2024. The vulnerability affects Microsoft Message Queuing service with a CVSS v3.1 base score of 8.1 (HIGH) (NVD).

The vulnerability has a CVSS vector of CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating it is network accessible, requires high attack complexity, needs no privileges or user interaction, and can result in high impacts to confidentiality, integrity, and availability. The vulnerability is associated with CWE-362 (Race Condition) and CWE-416 (Use After Free) (NVD).

Successful exploitation of this vulnerability requires an attacker to win a race condition. An attacker would need to send a specially crafted malicious MSMQ packet to a MSMQ server, which could result in remote code execution on the server side. The service needs to be enabled and network traffic allowed on TCP port 1801 for successful exploitation (CrowdStrike).

Microsoft recommends checking if the 'Message Queuing' service is running and TCP port 1801 is listening on the machine. If the service is running and not being utilized, consider disabling it. Additionally, patching the system with the latest security updates is recommended (CrowdStrike).
