CVE-2025-24053 is a vulnerability classified under CWE-285 (Improper Authorization) affecting Microsoft Dataverse, a cloud-based data platform used for building and managing business applications. The vulnerability allows an attacker who is already authorized on the network to escalate their privileges beyond their intended scope. This improper authorization flaw means that the system fails to adequately verify whether the user has the necessary permissions to perform certain privileged actions. The attack vector is network-based with low attack complexity, requiring no user interaction but necessitating that the attacker has some level of authorized access (PR:H). The vulnerability impacts confidentiality, integrity, and availability, allowing attackers to potentially access sensitive data, modify or delete data, and disrupt services. The CVSS 3.1 score of 7.2 (High) reflects these impacts, with partial exploitability (E:P) and official remediation (RL:O) expected. No patches or exploits are currently publicly available, but the vulnerability is officially published and enriched by CISA, indicating its recognized importance. Given Microsoft Dataverse's integration with Microsoft Power Platform and widespread use in enterprise environments, this vulnerability poses a significant risk to organizations relying on these services for critical business operations.

For European organizations, the impact of CVE-2025-24053 can be substantial. Microsoft Dataverse is widely used across various industries including finance, healthcare, manufacturing, and public sector entities in Europe. An attacker exploiting this vulnerability could gain unauthorized elevated privileges, leading to unauthorized access to sensitive personal data protected under GDPR, manipulation or deletion of critical business data, and disruption of business processes. This could result in regulatory penalties, reputational damage, and operational downtime. The network-based nature of the attack means it could be launched remotely, increasing the risk of widespread exploitation if attackers gain initial access. Organizations with complex role-based access controls and extensive use of Dataverse for automation and data workflows are particularly vulnerable. The lack of current exploits provides a window for proactive mitigation, but the high severity demands urgent attention.

1. Monitor and audit privilege escalations within Microsoft Dataverse environments to detect anomalous activities early. 2. Enforce strict role-based access controls (RBAC) and the principle of least privilege to limit the potential impact of compromised accounts. 3. Segment network access to Dataverse services, restricting access to trusted IP ranges and using conditional access policies. 4. Apply Microsoft security updates and patches promptly once released; maintain close communication with Microsoft security advisories. 5. Implement multi-factor authentication (MFA) for all users accessing Dataverse to reduce the risk of credential compromise. 6. Use Microsoft Defender for Cloud Apps or similar tools to monitor and respond to suspicious activities related to Dataverse. 7. Conduct regular security training for administrators and users to recognize and report unusual behavior. 8. Review and harden integration points between Dataverse and other Microsoft Power Platform components to minimize attack surface.
