CVE-2024-38182
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedWeak authentication in Microsoft Dynamics 365 allows an unauthenticated attacker to elevate privileges over a network.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an authentication weakness in Microsoft Dynamics 365 that allows an unauthenticated attacker to bypass authentication mechanisms and elevate privileges to higher-level accounts over the network. The vulnerability is remotely exploitable without any prior credentials.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Dynamics 365 installed versionCheck the Microsoft Dynamics 365 instance version through the admin center, Power Platform admin center, or via PowerShell cmdlets (Get-AdminPowerAppEnvironment or similar). Navigate to the Dynamics 365 admin portal and locate the version information in the environment details.Affected if The installed version is exactly 7.0 (the affected version)
-
Confirm network exposure of Dynamics 365 instanceDetermine whether the Dynamics 365 instance is accessible from the internet. Review firewall rules, Azure AD application proxy settings, or any DMZ configurations that expose the Dynamics 365 URL to unauthenticated external access.Affected if The instance is directly exposed to the internet without VPN or proper network segmentation, enabling unauthenticated attackers to reach the authentication endpoint
-
Review Azure AD conditional access policiesInspect conditional access policies in Azure Active Directory associated with Dynamics 365. Check if policies require multifactor authentication, device compliance, or trusted locations for all access attempts.Affected if Weak or missing conditional access policies are configured, allowing anonymous or untrusted connections to reach the Dynamics 365 authentication endpoints
-
Audit user roles and privilege assignmentsUse the Dynamics 365 admin center or PowerShell (Get-CrmUserRole) to enumerate all security roles and user privilege assignments. Look for unexpected administrative roles or elevated privileges assigned to service accounts or external users.Affected if Unrecognized accounts have been granted System Administrator, System Customizer, or other high-privilege roles, suggesting potential exploitation
-
Check for suspicious audit logsReview Microsoft Purview compliance portal or Dynamics 365 audit logs for failed authentication attempts followed by successful privileged actions, or for sign-in events from unusual IP addresses or locations.Affected if Audit logs show privilege escalation events, bulk data exports, or configuration changes performed by accounts without prior legitimate access patterns
You are affected if your Dynamics 365 version is exactly 7.0 AND the instance is network-accessible, as the pre-authentication bypass allows remote unauthenticated attackers to gain elevated privileges.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply Microsoft security updates for Dynamics 365 as soon as they become available. Until then, restrict network access to Dynamics 365 endpoints using conditional access policies and monitor for suspicious authentication patterns.
Apply Microsoft July 2024 Security Updates (KB5002537 or subsequent relevant updates for Dynamics 365)
- Identify the current Microsoft Dynamics 365 (on-premises) version running in your environment
- Apply the July 2024 security updates from Microsoft for Microsoft Dynamics 365
- Verify the update was applied successfully by checking the system version or applying the patch in a test environment first
- After applying the update, validate that the weak authentication vulnerability is remediated
- Ensure proper authentication mechanisms are enforced post-update
