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
Tyler Technologies Magistrate Court Case Management Plus allows an unauthenticated, remote attacker to upload, delete, and view files by manipulating the PDFViewer.aspx 'filename' parameter.

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

Tyler Technologies Magistrate Court Case Management Plus contains a path traversal or file inclusion vulnerability in PDFViewer.aspx. The 'filename' parameter is not properly validated, allowing unauthenticated remote attackers to manipulate it for arbitrary file upload, deletion, and viewing on the server file system.

MitigationImmediately restrict network access to the PDFViewer.aspx endpoint from untrusted sources while awaiting the vendor patch. Implement web application firewall rules to block path traversal patterns in the filename parameter.

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 Tyler Technologies Court Case Management Plus is installed
    Locate the application installation directory, typically under the web server's root (IIS wwwroot) or custom application paths. Search for files named 'PDFViewer.aspx' or directories containing 'CourtCaseManagement' or similar naming patterns from Tyler Technologies.
    Affected if The product is installed and PDFViewer.aspx exists in the web application directory structure.
  2. Verify PDFViewer.aspx endpoint is accessible
    Attempt to access the PDFViewer.aspx page via HTTP/HTTPS request (e.g., GET /PDFViewer.aspx or /path/to/PDFViewer.aspx). Check if the page loads or returns a valid HTTP response rather than a 404 error.
    Affected if The endpoint returns a valid response (200 OK, 403, or other non-404 status), indicating the page exists and is reachable.
  3. Determine if the application is exposed to untrusted networks
    Review firewall rules, network ACLs, and IIS/site bindings to determine if the web server hosting the application is accessible from public IP addresses or untrusted internal networks. Check whether the site requires authentication for access.
    Affected if The application is accessible without VPN or authentication from networks outside the trusted internal environment.
  4. Inspect web application logs for path traversal attempts
    Review IIS logs (typically in C:\inetpub\logs\LogFiles or /var/log/httpd) and application logs for requests to PDFViewer.aspx containing suspicious patterns in the filename parameter such as '../', '..\', or absolute paths (e.g., filename=../../windows/win.ini).
    Affected if Log analysis reveals exploitation attempts or unusual filename parameter values targeting path traversal.

The environment is affected if Tyler Technologies Court Case Management Plus is installed with PDFViewer.aspx accessible from untrusted networks without WAF protection blocking path traversal patterns in the filename parameter.
