CVE-2025-47732 is a high-severity vulnerability identified in Microsoft Dataverse, a cloud-based data platform widely used for building and managing business applications and data. The vulnerability is classified under CWE-502, which pertains to the deserialization of untrusted data. This type of vulnerability arises when an application deserializes data from an untrusted source without sufficient validation, allowing attackers to manipulate the serialized data to execute arbitrary code. In this case, the vulnerability enables remote code execution (RCE) on affected Microsoft Dataverse instances. The CVSS 3.1 base score of 8.7 reflects the critical nature of this flaw, with an attack vector of network (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), and user interaction (UI:R). The scope is changed (S:C), indicating that exploitation can affect resources beyond the initially vulnerable component. The impact on confidentiality and integrity is high (C:H/I:H), while availability impact is none (A:N). Although no known exploits are currently reported in the wild, the vulnerability's characteristics suggest that a successful attack could allow an adversary to execute arbitrary code remotely, potentially leading to data breaches, unauthorized data manipulation, or lateral movement within an organization's environment. The lack of specified affected versions and absence of patch links suggest that this is a newly disclosed vulnerability, and organizations using Microsoft Dataverse should prioritize monitoring for updates and mitigations from Microsoft. Given the critical role of Microsoft Dataverse in enterprise data management and application development, this vulnerability represents a significant risk if left unaddressed.

For European organizations, the impact of CVE-2025-47732 could be substantial due to the widespread adoption of Microsoft Dataverse in various sectors including finance, healthcare, manufacturing, and public administration. Exploitation could lead to unauthorized access to sensitive personal and corporate data, violating GDPR and other data protection regulations, potentially resulting in heavy fines and reputational damage. The ability to execute remote code could allow attackers to implant persistent backdoors, manipulate business-critical data, or disrupt operations by compromising integrated applications. Given the interconnected nature of enterprise systems, a successful exploit could facilitate lateral movement, increasing the risk of broader network compromise. Additionally, the requirement for user interaction and low privilege level for exploitation means that phishing or social engineering campaigns could be leveraged to trigger the vulnerability, increasing the attack surface. The high confidentiality and integrity impact underscores the threat to data privacy and trustworthiness, which are paramount for compliance and operational continuity in Europe.

European organizations should implement a multi-layered mitigation strategy beyond generic patching advice. First, they should immediately inventory all deployments of Microsoft Dataverse and related applications to assess exposure. Until official patches are released, organizations should apply strict network segmentation and firewall rules to limit external and internal access to Dataverse services, reducing the attack surface. Employing application-layer gateways or web application firewalls (WAFs) with custom rules to detect and block suspicious serialized data payloads can provide interim protection. User awareness training should be intensified to reduce the risk of social engineering attacks that could trigger the vulnerability. Monitoring and logging of Dataverse activity should be enhanced to detect anomalous behavior indicative of exploitation attempts. Organizations should also prepare incident response plans specific to this vulnerability, including rapid isolation and forensic analysis capabilities. Finally, once Microsoft releases patches or updates, organizations must prioritize timely deployment and validate the effectiveness of the fixes in their environments.
