Critical Vulnerability in MOVEit Software Puts 1,800 Networks at Risk

A critical security vulnerability has been discovered in Progress Software's MOVEit, a widely used file transfer software, potentially endangering around 1,800 networks globally with severe cybersecurity breaches. Labeled as CVE-2024-5806, the flaw enables unauthorized access to sensitive data through the software's SFTP module, carrying a severity rating of 9.1 out of 10. This vulnerability follows a similar breach last year that impacted over 2,300 organizations, including major entities like Shell and British Airways.

Progress Software has promptly released patches for affected versions of MOVEit and urges immediate updates from users. Additionally, the company recommends blocking inbound RDP access and limiting outbound access from MOVEit servers to trusted endpoints. Considering the significant data compromises stemming from last year's breach, including the exposure of information for 3.4 million individuals in Ontario, swift action is imperative to avert similar outcomes.

Key Takeaways

  • Critical vulnerability in MOVEit software puts 1,800 networks at risk.
  • Attackers actively exploit CVE-2024-5806 to bypass authentication.
  • Vulnerability allows hackers to use null strings as public encryption keys.
  • Progress Software advises blocking inbound RDP access and restricting outbound access.
  • Fixes available for MOVEit Transfer versions 2023.0.11, 2023.1.6, and 2024.0.2.


The vulnerability in Progress Software's MOVEit, identified as CVE-2024-5806, exposes nearly 1,800 networks to severe cyber threats, leveraging weaknesses in authentication and encryption. This flaw, similar to a previous breach affecting over 2,300 organizations, could lead to significant data leaks and operational disruptions. Immediate patching and enhanced security measures, such as blocking inbound RDP and restricting outbound access, are critical to mitigate risks. Long-term, this incident underscores the need for robust security protocols in file transfer systems and highlights the vulnerability of widely used software to sophisticated cyber attacks.

Did You Know?

  • CVE-2024-5806: This Common Vulnerabilities and Exposures (CVE) identifier points to a critical vulnerability in Progress Software's MOVEit, facilitating authentication bypass in the software's SFTP module. The severity rating of 9.1 out of 10 indicates a high risk of exploitation, potentially leading to significant data breaches.
  • SFTP Module: SFTP, or Secure File Transfer Protocol, is a network protocol enabling file transfer and manipulation capabilities over reliable data streams. In the context of MOVEit, the SFTP module's compromise allows unauthorized access and manipulation of files. Understanding SFTP is crucial as it is widely used in secure file transfers across networks.
  • Null String as Public Encryption Key: Attackers exploit the vulnerability in MOVEit by utilizing a null string as a public encryption key, enabling unauthorized access to manipulate files. This technique reveals a significant security oversight in the software's authentication process.
