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

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

The PasswordReset.Controllers.ResetController.ChangePasswordIndex method in Dovestones AD Self Password Reset.dll before version 3.0.4.0 contains an authentication bypass vulnerability allowing unauthenticated remote attackers to reset arbitrary user passwords by submitting crafted requests with valid usernames. This enables complete account takeover of any AD user account.

MitigationUpgrade Dovestones AD Self Password Reset to version 3.0.4.0 or later to patch the insecure direct object reference in the password reset controller. If immediate upgrade is not possible, disable the password reset functionality or restrict network access to the reset endpoint.

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. Locate the Dovestones AD Self Password Reset.dll file
    Search the application installation directory for 'Dovestones AD Self Password Reset.dll' - typically found in the bin folder of the web application hosting the password reset functionality
    Affected if The DLL file exists in the application directory, indicating the affected component is installed
  2. Check the file version of the DLL
    Right-click the DLL file, select Properties, then view the Details tab to find the 'File version' or 'Product version' field. Alternatively, use PowerShell: (Get-Item 'path\to\Dovestones AD Self Password Reset.dll').VersionInfo
    Affected if The version number is 3.0.3.0 or lower, placing it within the vulnerable range
  3. Identify the password reset endpoint exposure
    Check the application's web.config or routing configuration to locate the URL path for the ResetController, typically exposed under a path containing 'Reset' or 'PasswordReset'. Also check IIS site bindings to confirm which network addresses this application responds to
    Affected if The password reset endpoint (ChangePasswordIndex) is accessible over the network without authentication requirements configured
  4. Verify unauthenticated access to ChangePasswordIndex
    Using a browser or HTTP tool (such as curl or Invoke-WebRequest), attempt to access the ResetController.ChangePasswordIndex URL directly without providing any authentication credentials. For example: GET https://[server]/PasswordReset/Reset/ChangePasswordIndex
    Affected if The request returns a valid password reset page or form without requiring login credentials, confirming the authentication bypass is present

A user is affected if Dovestones AD Self Password Reset.dll version 3.0.3.0 or lower is installed AND the password reset endpoint is network-accessible without authentication, allowing unauthenticated password reset requests.
