What is the MOVEit Vulnerability?

MOVEit, developed by Progress Software, is a managed file transfer software that provides secure and compliant transfer of sensitive data among partners, customers, users, and systems. The software is widely used across various industries, which explains why it’s a prime target for cyber attackers looking to exploit critical vulnerabilities in popular software.

Description of the Vulnerability

Recently, a severe vulnerability identified in MOVEit Transfer (CVE-2023-34362) came under the spotlight. It is an SQL injection vulnerability that allows an unauthenticated attacker to gain access to the MOVEit Transfer’s database. Depending on the database engine used (MySQL, Microsoft SQL Server, or Azure SQL), an attacker can infer information about the database’s structure and contents and execute SQL statements that can alter or delete database elements. What distinguishes this vulnerability is its status as a zero-day vulnerability, meaning it was actively exploited before a patch was available. Unpatched systems can be exploited via HTTP or HTTPS, underscoring the urgency for companies using MOVEit Transfer to mitigate their risk immediately. This vulnerability became a hot topic in the cybersecurity community, primarily due to the British Airways data breach in June 2023, traced back to this zero-day vulnerability.

Products Affected

The MOVEit Transfer versions preceding 2021.0.6 (13.0.6), 2021.1.4 (13.1.4), 2022.0.4 (14.0.4), 2022.1.5 (14.1.5), and 2023.0.1 (15.0.1) are affected by this vulnerability. It’s critical to note that all versions prior to these (e.g., 2020.0 and 2019x) are also impacted, including older unsupported versions.

Companies Affected

A Shodan search on June 5, 2023, revealed that 2,516 servers were vulnerable to this specific SQL injection. A substantial majority of these servers (1,800+) are located in the United States, with the United Kingdom, Germany, Canada, and the Netherlands also hosting a significant number of vulnerable servers. The specific number of companies affected may be far larger than this figure, given that a single company may own multiple servers or a server may host data for more than one company


Threat Actors: Lace Tempest and Clop Ransomware Group

Before delving into the risk from a third-party risk management perspective, it’s important to understand the threat actors exploiting the MOVEit vulnerability. Primarily, the threat actors exploiting this vulnerability belong to a notorious ransomware group known as Lace Tempest, believed to be the extortion arm of the infamous Clop ransomware group.

According to our latest research report, Clop ransomware group, active since 2019, is known for its hit-and-run mass-ransomware attacks, exploiting large-scale vulnerabilities without targeting specific organizations. The group resurfaced in March 2023, launching a mass-ransomware campaign that exploited a high-severity Fortra GoAnywhere vulnerability. This opportunistic approach, coupled with their capacity to exploit zero-day vulnerabilities, as seen in the MOVEit case, makes them a significant threat in the cybersecurity landscape.

Lace Tempest has been linked to numerous cyberattacks targeting organizations running vulnerable versions of the MOVEit software. They’ve been found exploiting the MOVEit vulnerability to gain unauthorized access to an organization’s network, subsequently deploying ransomware or performing other malicious activities.

The connection between the Lace Tempest attacks and the Clop ransomware group has been made based on the ransomware variants used in these attacks, which are nearly identical to those previously attributed to the Clop group. The tactics, techniques, and procedures (TTPs) used by Lace Tempest also closely align with those used by the Clop group in their earlier campaigns.

Understanding the threat actors behind the attacks not only helps in developing effective response strategies but also provides insight into the potential risks posed by the MOVEit vulnerability to organizations and their third-party networks. Given their history of exploiting zero-day vulnerabilities and conducting mass-ransomware campaigns, organizations and their vendors using MOVEit software should be particularly cautious.

Next, we’ll delve into the third-party risk posed by the MOVEit vulnerability, exemplified by the recent British Airways data breach.

The Risk from a Third-Party Risk Management Perspective

The MOVEit vulnerability doesn’t only affect the organizations directly using vulnerable versions, but it also presents substantial risks to their business partners and customers – a perspective that comes into sharper focus when considering third-party risk management (TPRM). TPRM is a strategic approach to managing risks associated with external parties that have access to an organization’s sensitive data or systems.

Case in Point: British Airways Data Breach

In June 2023, British Airways, one of the largest global airlines, became a victim of this critical MOVEit vulnerability when a third-party supplier of payroll support services, Zellis UK Ltd., experienced a cybersecurity incident. This incident compromised personal data of thousands of British Airways employees, including highly sensitive details such as bank account details, national security numbers, home addresses, and dates of birth.

This breach was traced back to the zero-day vulnerability in the MOVEit file transfer tool, indicating the ripple effect of such vulnerabilities in a third-party risk landscape. British Airways isn’t the only company using Zellis’ software; Many other companies use the same software for managing their payroll systems, illustrating how one vulnerable vendor could potentially impact multiple businesses.

Such incidents underscore the importance of an effective TPRM strategy. Organizations not only need to be aware of their own cybersecurity posture but also the security measures and vulnerabilities of their vendors. If a third-party vendor has access to an organization’s sensitive data, vulnerabilities in the vendor’s systems could lead to the organization’s data being compromised, as was the case with British Airways. This is why third-party risk management is crucial in today’s interconnected business ecosystem.

Understanding and managing the cybersecurity risks presented by third-party relationships, including vendors, suppliers, and partners, is a vital component of a robust cybersecurity strategy. Identifying vulnerabilities in third-party systems and mitigating the associated risks can protect organizations from potential breaches and the associated financial impact and potential damage to reputation.
