CVE-2026-47643
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 · uneditedExternal control of file name or path in Azure Stack Edge allows an unauthorized attacker to execute code 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 confidenceA path traversal vulnerability in Azure Stack Edge allows an unauthenticated attacker to control file paths and execute arbitrary code remotely over the network. This critical flaw enables complete system compromise without authentication.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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.
-
Check Azure Stack Edge device versionAccess the Azure portal, navigate to your Azure Stack Edge resource, and locate the Device information section. Alternatively, connect to the local management UI on the device and find the version information typically displayed on the dashboard or About page.Affected if The installed version number is lower than 3.3.2604.3097
-
Verify management interface exposureReview network configuration to determine if the Azure Stack Edge management interfaces (Azure portal access, PowerShell remoting, local web UI) are accessible from untrusted or external networks.Affected if Management interfaces are exposed to the internet or untrusted internal networks without VPN or IP restriction filters
-
Audit file system for unexpected filesUse the local management interface or PowerShell to examine the file shares and storage accounts on the device for unfamiliar files, particularly in system directories or the upload folders used by the file operation features.Affected if Unexpected or suspicious files are found in directories used for file operations, especially files with unexpected extensions like .exe, .ps1, or .dll in upload paths
-
Review access logs for anomalous file operationsCheck Azure Stack Edge activity logs and IIS logs (if accessible) for file operation requests that contain path traversal patterns such as '../', '..\', or absolute path references in file name parameters.Affected if Logs show file operation requests with directory traversal sequences or access to files outside expected share boundaries
The environment is affected if the installed Azure Stack Edge version is below 3.3.2604.3097 AND the device management interfaces are network-accessible to potential attackers.

Apply the latest Microsoft security update for Azure Stack Edge. Review Microsoft advisory and coordinate with Microsoft support for patch deployment during a planned maintenance window.
Azure Stack Edge version 3.3.2604.3097 or later
- 1. Identify the current Azure Stack Edge device version via the Azure portal or local management interface
- 2. Plan for a maintenance window as the update may require downtime
- 3. Back up any critical data and configurations on the Azure Stack Edge device
- 4. Initiate the update through Azure Portal: Navigate to the Azure Stack Edge resource, select 'Updates' under 'Device', and apply the latest available update
- 5. Alternatively, use PowerShell or the local web UI to apply the update package
- 6. Verify the device has updated to version 3.3.2604.3097 or later
- 7. Validate that the Azure Stack Edge services are functioning correctly post-update
