vulnerability analysis and mitigation

Microsoft Message Queuing (MSMQ) Remote Code Execution Vulnerability (CVE-2024-30080) was disclosed on June 11, 2024. This critical vulnerability affects Microsoft Message Queuing service across multiple versions of Windows and Windows Server operating systems. The vulnerability has been assigned a CVSS v3.1 base score of 9.8 (CRITICAL), indicating its severe nature (NVD, Rapid7).

The vulnerability is classified as a Use After Free (CWE-416) flaw in the Microsoft Message Queuing (MSMQ) service. It can be triggered by an unauthenticated attacker sending a specially crafted malicious MSMQ packet to a MSMQ server. The vulnerability's CVSS vector string is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating that it can be exploited over the network with low attack complexity, requires no privileges or user interaction, and can result in high impacts to confidentiality, integrity, and availability (Help Net Security).

Successful exploitation of this vulnerability could allow an unauthenticated attacker to execute remote code on the affected system. The vulnerability affects systems with the Windows message queuing service enabled, and Microsoft has indicated that exploitation is 'more likely' due to the lack of additional exploitation requirements such as authentication or user interaction (Help Net Security).

Microsoft has released security updates to address this vulnerability across affected Windows versions. Organizations can either apply the available patches or disable the vulnerable Windows message queuing service if it is not required for operations (Help Net Security).
