CVE-2025-47732: Microsoft Dataverse RCE Vulnerability

CVE-2025-47732 Overview

CVE-2025-47732 is a critical remote code execution vulnerability affecting Microsoft Dataverse, the cloud-native data platform that underpins numerous Microsoft Power Platform applications and Dynamics 365 services. This vulnerability allows unauthenticated attackers to execute arbitrary code remotely on affected systems through the network without requiring user interaction.

Critical Impact

This vulnerability enables complete system compromise through remote code execution, potentially allowing attackers to gain full control over Microsoft Dataverse environments, access sensitive business data, and pivot to connected Microsoft services.

Affected Products

• Microsoft Dataverse (all versions prior to patch)
• Microsoft Power Platform environments utilizing Dataverse
• Dynamics 365 applications built on Dataverse infrastructure

Technical Details for CVE-2025-47732

Vulnerability Analysis

This remote code execution vulnerability in Microsoft Dataverse stems from insecure deserialization (CWE-502), a class of vulnerabilities where untrusted data is deserialized without proper validation. When exploited, an attacker can craft malicious serialized objects that, upon deserialization by the Dataverse platform, execute arbitrary code within the application context.

The vulnerability is network-accessible and requires no authentication or user interaction to exploit successfully. This makes it particularly dangerous in cloud environments where Dataverse instances may be exposed to the internet as part of normal business operations. The potential impact includes complete compromise of confidentiality, integrity, and availability of the affected system and any data stored within the Dataverse environment.

Root Cause

The root cause of CVE-2025-47732 is an insecure deserialization vulnerability (CWE-502) within Microsoft Dataverse. The application fails to properly validate or sanitize serialized data before deserializing it, allowing attackers to inject malicious objects that execute code during the deserialization process. This type of vulnerability commonly occurs when applications accept serialized data from untrusted sources and process it without implementing appropriate security controls such as type allowlisting or integrity verification.

Attack Vector

The attack vector for this vulnerability is network-based, allowing remote attackers to exploit vulnerable Dataverse instances over the network. The attack requires low complexity to execute and does not require any privileges or user interaction, making it highly exploitable. An attacker would craft a specially formatted serialized payload containing malicious code and submit it to a vulnerable endpoint within the Dataverse application. Upon processing this payload, the application deserializes the malicious object, triggering code execution with the privileges of the Dataverse service.

The exploitation mechanism leverages the deserialization functionality within Dataverse to instantiate attacker-controlled objects. Technical details regarding specific endpoints and payload structures should be referenced in the Microsoft Security Update CVE-2025-47732.

Detection Methods for CVE-2025-47732

Indicators of Compromise

• Unusual outbound network connections from Dataverse services to external IP addresses
• Unexpected process spawning or child processes from Dataverse application pools
• Anomalous serialized data patterns in web requests targeting Dataverse endpoints
• Authentication logs showing unauthorized access attempts or successful access from suspicious IP ranges
• Unusual PowerShell or command execution events correlated with Dataverse service activity

Detection Strategies

• Implement network traffic analysis to identify suspicious serialized payloads in requests to Dataverse endpoints
• Deploy endpoint detection solutions to monitor for unexpected code execution within Dataverse service contexts
• Enable enhanced logging for Microsoft Dataverse and Power Platform environments to capture detailed request information
• Configure SIEM rules to alert on patterns consistent with deserialization attack attempts

Monitoring Recommendations

• Enable Microsoft Defender for Cloud Apps to monitor Power Platform and Dataverse activity
• Review Azure Activity Logs for unusual administrative actions on Dataverse resources
• Monitor for failed authentication attempts that may indicate reconnaissance activity
• Implement real-time alerting for any detected exploitation attempts through SentinelOne Singularity platform

How to Mitigate CVE-2025-47732

Immediate Actions Required

• Apply the security update from Microsoft immediately to all Dataverse environments
• Review access logs for any signs of exploitation prior to patching
• Implement network segmentation to limit exposure of Dataverse services where possible
• Ensure all connected applications and integrations are also updated to mitigate supply chain risks

Patch Information

Microsoft has released a security update addressing CVE-2025-47732. As Dataverse is a cloud-managed service, Microsoft handles patching for most deployments automatically. Organizations should verify their Dataverse environments have received the update by consulting the Microsoft Security Update CVE-2025-47732 for specific version information and deployment guidance.

For on-premises or hybrid deployments, administrators should apply the security update through standard Microsoft update channels and verify successful installation. Organizations using Dynamics 365 or Power Platform applications should ensure their underlying Dataverse instances are updated.

Workarounds

• Restrict network access to Dataverse endpoints using firewall rules or Azure Network Security Groups to trusted IP ranges only
• Implement Web Application Firewall (WAF) rules to filter potentially malicious serialized payloads
• Enable additional authentication requirements for sensitive Dataverse operations until patching is complete
• Monitor environments closely for exploitation attempts while workarounds are in place

Organizations should consult the official Microsoft Security Response Center advisory for the most current mitigation guidance and apply patches as the primary remediation strategy.
