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 neutralization of input during web page generation ('cross-site scripting') in Azure Stack Edge allows an authorized attacker to perform spoofing 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 confidence

An XSS (cross-site scripting) vulnerability exists in Azure Stack Edge's web interface where user input is not properly neutralized during web page generation. An authenticated attacker can inject malicious scripts that execute in the context of other users' sessions, enabling session hijacking and spoofing attacks.

MitigationApply Microsoft security updates for Azure Stack Edge as they become available; until then, restrict administrative access to trusted personnel and monitor for anomalous administrative sessions.

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. Identify if running Azure Stack Edge
    Confirm the system is a Microsoft Azure Stack Edge device by checking the device model, documentation, or accessing the management interface at the local device IP address
    Affected if System is not an Azure Stack Edge device - this CVE does not apply
  2. Determine Azure Stack Edge version
    Access the device web portal or use PowerShell cmdlets such as Get-AzStackEdgeDevice to retrieve the installed software version
    Affected if Unable to retrieve version information - version cannot be confirmed
  3. Compare version against affected range
    Compare the installed version number to 3.3.2604.3097 - the vulnerability affects versions lower than this threshold
    Affected if Installed version is 3.3.2604.3097 or higher - the version is not in the affected range
  4. Verify web management interface accessibility
    Confirm the Azure Stack Edge web-based management portal is accessible and operational
    Affected if Web interface is not enabled or accessible - the attack surface may not be present

If the device is Azure Stack Edge with a version lower than 3.3.2604.3097 and the web management interface is enabled, the environment is affected by this XSS vulnerability.
