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 · unedited
Improper access control in Azure Monitor Agent allows an authorized attacker to elevate privileges locally.

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 confidence

Azure Monitor Agent has an improper access control vulnerability that allows an already-authorized attacker to escalate privileges locally on the affected system. The issue stems from insufficient access control checks within the agent, enabling a user with basic privileges to gain higher-level access.

MitigationApply the vendor patch for Azure Monitor Agent when available. Until then, restrict access to the Azure Monitor Agent service and monitor for suspicious process activity.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Azure Monitor Agent is installed
    Check for the Azure Monitor Agent service on the system. On Windows, run 'Get-Service' or check Services.msc for 'Azure Monitor Agent' or 'AMA'. On Linux, check for 'azuremonitoragent' service via 'systemctl list-unit-files' or similar.
    Affected if The service or application named Azure Monitor Agent or AMA is found on the system
  2. Identify installed version
    Retrieve the version of the Azure Monitor Agent. On Windows, check the file properties of the binary (typically in Program Files\Azure Monitor Agent\), or use 'Get-ItemProperty' on the registry key for the installed program. On Linux, run 'dpkg -l' or 'rpm -qi' for the azuremonitoragent package.
    Affected if The version number is lower than 1.38.1 (for example, 1.37.0, 1.36.0, etc.)
  3. Verify if the agent service is running
    Check if the Azure Monitor Agent service is currently active. On Windows, run 'Get-Service -Name AzureMonitorAgent' or check status in Services.msc. On Linux, run 'systemctl status azuremonitoragent' or check if the process is running.
    Affected if The service shows as Running or the process is active in memory
  4. Assess user context and access
    Determine the privilege level of the user checking the system. The vulnerability allows a user with basic (non-admin) privileges to escalate. Check current user privileges using 'whoami /groups' on Windows or 'id' on Linux, noting if the user is in administrators or has elevated rights.
    Affected if The current user has standard user privileges (not administrator) and the Azure Monitor Agent service is running with higher privileges than the current user

If Azure Monitor Agent version is below 1.38.1 and the service is running on the system, the environment is potentially affected by this privilege escalation vulnerability.
