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
ITCube CRM in versions from 2023.2 through 2025.2 is vulnerable to path traversal. Unauthenticated remote attacker is able to exploit vulnerable parameter fileName and construct payloads that allow to download any file accessible by the the web server process.

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

ITCube CRM versions 2023.2-2025.2 contains a path traversal vulnerability in the fileName parameter. Unauthenticated remote attackers can craft payloads using directory traversal sequences (e.g., ../../) to access and download arbitrary files from the web server's filesystem, potentially exposing sensitive system files, configuration data, credentials, or application data.

MitigationImplement strict input validation on the fileName parameter to reject path traversal sequences, enforce allowlist-based file access controls, and ensure the web server process runs with minimal necessary filesystem privileges. Consider deploying a WAF rule as an interim control.

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. Check installed ITCube CRM version
    Locate the ITCube CRM installation directory and check version files (typically version.txt, about page, or admin panel) or query the application's /about or /version endpoint if available
    Affected if Installed version is 2023.2, 2023.3, 2024.1, 2024.2, 2025.1, or 2025.2 (any version between 2023.2 and 2025.2 inclusive)
  2. Identify if file download functionality is exposed
    Check for endpoints that accept a fileName parameter, typically in file download, attachment retrieval, or document viewer modules. Common patterns include URLs like /download, /file/get, /documents/view, or similar paths handling fileName as a query or POST parameter
    Affected if The application exposes any endpoint accepting a fileName parameter for file retrieval
  3. Verify web server user privileges
    Inspect the process owner of the web server (IIS, Apache, Nginx) and check what directories that user account can access. Look for excessive permissions on system directories (C:\ on Windows or / on Linux)
    Affected if The web server process runs with elevated privileges or has read access to sensitive directories outside the application root
  4. Review access logs for path traversal attempts
    Search web server access logs (IIS logs in %SystemDrive%\inetpub\logs\LogFiles or Apache/Nginx logs in /var/log) for requests containing ../ sequences in fileName, download, or similar parameters
    Affected if Log analysis reveals any GET or POST requests with ../ patterns targeting the fileName parameter

You are affected if ITCube CRM version 2023.2-2025.2 is installed AND the file download feature accepting a fileName parameter is exposed to unauthenticated users.
