256,000+ Publicly Exposed Windows Servers Vulnerable to MSMQ RCE Flaw

Cybersecurity watchdog Shadowserver has identified 256,000+ publicly exposed servers vulnerable to a critical Remote Code Execution (RCE) flaw in Microsoft Message Queuing (MSMQ) services.

The flaw, designated CVE-2024-30080, poses a significant threat to global cybersecurity. It could allow malicious actors to execute arbitrary code on affected systems.

CVE-2024-30080 is a critical RCE vulnerability in MSMQ, a messaging protocol used for communication between applications.

The flaw allows attackers to send specially crafted packets to the MSMQ service, enabling them to execute arbitrary code with the same privileges as the MSMQ service.

This could lead to unauthorized access, data breaches, and potentially severe disruptions in services relying on MSMQ.

Scope of Exposure

Shadowserver’s extensive scan revealed that approximately 256,000 servers worldwide are publicly exposed and vulnerable to this flaw.

Shadowserver report

These servers span various industries, including finance, healthcare, and government sectors, highlighting the widespread risk posed by this vulnerability.

Mitigation Measures

Microsoft has released a security patch addressing CVE-2024-30080. Organizations are strongly urged to apply this patch immediately to protect their systems. Additionally, it is recommended to:

  1. Restrict Access: Limit MSMQ service exposure to trusted networks only.
  2. Monitor Traffic: Implement network monitoring to detect and block suspicious activities targeting MSMQ services.
  3. Regular Updates: Ensure all systems and applications are updated with the latest security patches.

The widespread exposure of servers to CVE-2024-30080 underscores the critical need for robust cybersecurity practices.

The finding that 256,000 servers were publicly exposed and susceptible to the MSMQ RCE flaw (CVE-2024-30080) clearly indicates the ongoing cybersecurity difficulties.
