CVE-2025-11235 is a vulnerability identified in Progress MOVEit Transfer software, specifically affecting Windows deployments of the REST API modules. The flaw is categorized under CWE-620, which pertains to unverified password changes. This means that the software allows password changes without adequately verifying the legitimacy of the request, potentially enabling unauthorized password resets. The affected MOVEit Transfer versions include 2023.1.0 before 2023.1.3, 2023.0.0 before 2023.0.8, 2022.1.0 before 2022.1.11, and 2022.0.0 before 2022.0.10. The vulnerability has a CVSS 3.1 base score of 3.7, indicating low severity. The vector details (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) show that the attack can be performed remotely over the network but requires high attack complexity, no privileges, and no user interaction. The impact is limited to availability, with no confidentiality or integrity loss. No known exploits have been reported in the wild, and no patches were linked at the time of reporting. The vulnerability could allow an attacker to disrupt service by triggering unauthorized password changes, potentially causing denial of service or administrative confusion. However, the high complexity and lack of privilege requirements reduce the likelihood of exploitation. MOVEit Transfer is widely used for secure file transfer in enterprises, making this vulnerability relevant for organizations relying on it for critical data exchange.

For European organizations, the primary impact of CVE-2025-11235 lies in potential availability disruptions of MOVEit Transfer services. Since MOVEit Transfer is commonly used for secure file transfers in sectors such as finance, government, healthcare, and critical infrastructure, any service interruption could delay sensitive data exchanges and operational workflows. Although the vulnerability does not compromise confidentiality or integrity, denial of service or administrative confusion caused by unauthorized password changes could lead to temporary loss of access or increased support overhead. Organizations with high dependency on MOVEit Transfer for compliance-driven data transfers may face regulatory scrutiny if service disruptions affect data delivery timelines. The low severity and high attack complexity reduce immediate risk, but unpatched systems remain vulnerable to targeted disruption attempts. European entities operating MOVEit Transfer in multi-tenant or cloud environments should be cautious of potential lateral impacts if attackers exploit this flaw to cause cascading service interruptions.

1. Apply official patches from Progress as soon as they become available for the affected MOVEit Transfer versions. 2. Restrict network access to the REST API endpoints by implementing firewall rules or network segmentation to limit exposure only to trusted management and integration systems. 3. Monitor logs and audit trails for unusual or repeated password change requests, especially those originating from unexpected IP addresses or outside normal operational hours. 4. Enforce strong authentication and authorization controls around administrative interfaces to reduce the risk of unauthorized access attempts. 5. Consider implementing multi-factor authentication (MFA) for administrative accounts to add an additional layer of verification. 6. Regularly review and update MOVEit Transfer configurations to disable or limit unnecessary API functionalities. 7. Conduct internal security awareness and incident response drills to prepare for potential service disruptions. 8. Engage with Progress support channels for guidance and early access to patches or workarounds. These steps go beyond generic advice by focusing on network-level protections, monitoring, and operational readiness specific to the MOVEit Transfer environment.
