CVE-2024-30061 Overview
CVE-2024-30061 is an information disclosure vulnerability in Microsoft Dynamics 365 (On-Premises) version 9.1. The flaw stems from improper authorization [CWE-285], allowing an authenticated attacker to access data outside their permitted scope. Exploitation requires low-privilege authentication and user interaction over the network. Microsoft published guidance for the issue through the Microsoft Security Response Center. The vulnerability affects the confidentiality and integrity of data managed by the Dynamics 365 platform.
Critical Impact
Authenticated attackers can disclose sensitive Dynamics 365 business data and modify records after tricking a legitimate user into interacting with crafted content.
Affected Products
- Microsoft Dynamics 365 (On-Premises) 9.1
- Deployments exposing the Dynamics 365 web application to authenticated users
- Environments without the Microsoft security update for CVE-2024-30061

Technical Details for CVE-2024-30061
Vulnerability Analysis
The vulnerability resides in the authorization logic of Microsoft Dynamics 365 (On-Premises). The application fails to correctly enforce permissions on certain requests, allowing an authenticated user to retrieve information they should not access. Microsoft classifies the issue as an information disclosure flaw, but the CVSS vector also reports a high integrity impact, indicating the same authorization gap enables limited data tampering. Exploitation requires the attacker to hold valid credentials and to induce a legitimate user into performing an action, such as opening a crafted link or record.
Root Cause
The root cause is improper authorization [CWE-285] within the Dynamics 365 request-handling logic. The application processes requests without adequately verifying that the calling principal has the rights required for the target resource. Microsoft has not published low-level technical details of the affected component.
Attack Vector
The attack originates over the network against the Dynamics 365 web tier. The attacker authenticates as a low-privilege user and delivers a crafted request or content that a targeted user must interact with. Successful exploitation returns data belonging to other tenants, users, or business records. No verified public exploit is available, and the CISA Known Exploited Vulnerabilities catalog does not list this CVE. EPSS reports a probability of 1.373% (69.88 percentile).
No verified exploit code is publicly available. Refer to the Microsoft Vulnerability Guide for CVE-2024-30061 for vendor-provided details.
Detection Methods for CVE-2024-30061
Indicators of Compromise
- Unexpected read or export activity from low-privilege Dynamics 365 accounts against records they do not normally access.
- Web server logs showing repeated requests to Dynamics 365 endpoints with anomalous query parameters or record identifiers.
- Authenticated sessions originating from unusual geolocations or user agents shortly before bulk record retrieval.
- Audit log entries showing record modifications inconsistent with the acting user's role.
Detection Strategies
- Enable Dynamics 365 auditing for entity read, update, and export events and forward the audit stream to a central log platform.
- Baseline normal record-access volumes per user role and alert on statistical deviations.
- Correlate IIS or reverse-proxy access logs with Dynamics 365 audit events to identify authorization mismatches.
- Hunt for user-interaction lures such as suspicious Dynamics 365 URLs delivered through email or chat platforms.
Monitoring Recommendations
- Monitor privileged and service-account activity on the Dynamics 365 application and SQL Server backend continuously.
- Alert on any Dynamics 365 role assignment or privilege change that occurs outside approved change windows.
- Track failed and successful authentication attempts against the Dynamics 365 web endpoint and flag credential-stuffing patterns.
How to Mitigate CVE-2024-30061
Immediate Actions Required
- Apply the Microsoft security update referenced in the Microsoft Vulnerability Guide for CVE-2024-30061 to all Dynamics 365 (On-Premises) 9.1 servers.
- Inventory every on-premises Dynamics 365 deployment and confirm the patch state through configuration management data.
- Review Dynamics 365 security roles and remove excess privileges from standard users and service accounts.
- Enforce multi-factor authentication on all accounts that can reach the Dynamics 365 web tier.
Patch Information
Microsoft released a security update addressing CVE-2024-30061 through the Microsoft Security Response Center. Administrators should follow the guidance in the Microsoft Vulnerability Guide for CVE-2024-30061 and apply the corresponding cumulative update or hotfix for Dynamics 365 (On-Premises) 9.1. Validate the deployment in a staging environment before production rollout and confirm application functionality after installation.
Workarounds
- Restrict Dynamics 365 web access to trusted network segments using firewall rules or a reverse proxy while patching is scheduled.
- Reduce user privileges to the minimum required set to limit the data exposed if exploitation occurs.
- Increase user awareness training focused on unsolicited Dynamics 365 links and record-sharing requests, since exploitation requires user interaction.
