On June 13, 2024, cybersecurity watchdog Shadowserver reported that over 256,000 publicly exposed servers are vulnerable to a critical Remote Code Execution (RCE) flaw, designated CVE-2024-30080, in Microsoft Message Queuing (MSMQ) services. This vulnerability allows attackers to send specially crafted packets to the MSMQ service, enabling arbitrary code execution with the same privileges as the service. The flaw poses a significant threat to various sectors, including finance, healthcare, and government, potentially leading to unauthorized access, data breaches, and severe disruptions. Microsoft has released a security patch, and organizations are urged to apply it immediately, restrict MSMQ service exposure to trusted networks, monitor traffic, and ensure systems are regularly updated. The widespread exposure highlights the critical need for robust cybersecurity practices.
