CVE-2025-47732 is a high-severity vulnerability identified in Microsoft Dataverse, a cloud-based data platform that underpins many Microsoft Power Platform applications and services. The vulnerability is categorized under CWE-502, which involves deserialization of untrusted data. This type of vulnerability occurs when an application deserializes data from an untrusted source without sufficient validation, allowing an attacker to manipulate the serialized data to execute arbitrary code. In this case, the flaw enables remote code execution (RCE), meaning an attacker with limited privileges (PR:L) and requiring user interaction (UI:R) can exploit the vulnerability over a network (AV:N) with low attack complexity (AC:L). The vulnerability impacts confidentiality and integrity severely (C:H/I:H) but does not affect availability (A:N). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The CVSS 3.1 base score is 8.7, reflecting a high severity level. Although no known exploits are currently reported in the wild, the vulnerability's characteristics suggest that once weaponized, it could allow attackers to execute arbitrary code remotely, potentially leading to unauthorized data access, data manipulation, or lateral movement within affected environments. The absence of specified affected versions and patch links indicates that this is a newly disclosed vulnerability, and organizations using Microsoft Dataverse should prioritize monitoring for patches and advisories from Microsoft.

For European organizations, the impact of this vulnerability could be significant given the widespread adoption of Microsoft Dataverse within enterprises leveraging the Microsoft Power Platform for business-critical applications, data analytics, and automation workflows. Successful exploitation could lead to unauthorized access to sensitive data, including personal data protected under GDPR, resulting in potential data breaches and regulatory penalties. The integrity of business data could be compromised, affecting decision-making processes and operational continuity. Although availability is not directly impacted, the indirect effects of data corruption or unauthorized changes could disrupt business operations. Additionally, the ability to execute remote code could allow attackers to establish persistent footholds, escalate privileges, and move laterally within corporate networks, increasing the risk of broader compromise. European organizations with hybrid or cloud deployments integrating Dataverse with other Microsoft services may face compounded risks. The requirement for user interaction may limit automated exploitation but does not eliminate risk, especially in environments with high user activity and potential phishing or social engineering vectors.

To mitigate this vulnerability effectively, European organizations should: 1) Monitor Microsoft’s official security advisories closely for patches or updates addressing CVE-2025-47732 and apply them promptly once available. 2) Implement strict input validation and deserialization controls where custom integrations or extensions interact with Microsoft Dataverse to reduce the risk of untrusted data processing. 3) Employ network segmentation and least privilege principles to limit the potential impact of a compromised Dataverse instance, restricting access to sensitive data and critical systems. 4) Enhance user awareness training focusing on phishing and social engineering tactics that could trigger the required user interaction for exploitation. 5) Utilize advanced endpoint detection and response (EDR) solutions to detect anomalous behaviors indicative of exploitation attempts, such as unexpected code execution or lateral movement. 6) Review and harden authentication and authorization mechanisms around Dataverse access, including multi-factor authentication (MFA) and conditional access policies. 7) Conduct regular security assessments and penetration testing focusing on deserialization and remote code execution vectors within the Microsoft Power Platform ecosystem.
