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
An improper access control vulnerability was found in the EZ Sync Manager of ADM, which allows authenticated users to copy arbitrary files from the server file system into their own EZSync folder. The vulnerability is due to a lack of authorization checks on the file parameter of the HTTP request. Attackers can exploit this flaw to access files outside their authorized scope, provided the file has readable permissions for other users on the underlying OS. This can lead to unauthorized exposure of sensitive data. Affected products and versions include: from ADM 4.1.0 to ADM 4.3.3.RH61 as well as ADM 5.0.0.RIN1 and earlier.

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 · high confidence

Improper access control in EZ Sync Manager allows authenticated users to copy arbitrary files from the server filesystem into their own EZSync folder by manipulating the file parameter in HTTP requests without proper authorization validation.

MitigationImplement proper authorization checks on the file parameter to ensure users can only access files within their authorized scope, and validate that file paths do not traverse outside permitted directories.

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 EZ Sync Manager is installed
    Locate EZ Sync Manager installation by checking for its executable or service process on the system, typically in program files or application directories
    Affected if EZ Sync Manager software is present on the system
  2. Identify exposed HTTP endpoints
    Review web server configuration or application routing to find endpoints that handle file parameter requests, typically under /api/file, /sync/file, or similar paths
    Affected if Endpoints accepting a file parameter are publicly or internally accessible
  3. Verify authentication is enforced
    Test the identified endpoints by making requests without valid credentials to confirm authentication is required
    Affected if The file parameter endpoint accepts requests without valid authentication tokens
  4. Check authorization on file parameter
    Use an authenticated account to send requests with the file parameter pointing to paths outside the user's designated EZSync folder, such as ../../etc/passwd or absolute paths
    Affected if Requests succeed in accessing files outside the user's authorized directory scope
  5. Inspect path traversal protections
    Analyze the application's code or proxy logs to determine if the file parameter is validated against directory traversal patterns like ../ or absolute path inputs
    Affected if The application does not reject or sanitize path traversal sequences in the file parameter
  6. Review access logs for anomalies
    Search application and web server logs for unusual file parameter requests that may indicate exploitation, looking for access to system files outside the sync directory
    Affected if Logs show file parameter requests accessing paths outside the intended sync folder

A user is affected if EZ Sync Manager is running and the file parameter endpoint can be manipulated by authenticated users to access files outside their authorized EZSync folder scope.
