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
Ilevia EVE X1 Server version ≤ 4.7.18.0.eden contains a pre-authentication file disclosure vulnerability via the 'db_log' POST parameter. Remote attackers can retrieve arbitrary files from the server, exposing sensitive system information and credentials.

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

The Ilevia EVE X1 Server versions 4.7.18.0 and below contains a pre-authentication path traversal vulnerability in the 'db_log' POST parameter. Remote unauthenticated attackers can manipulate this parameter to read arbitrary files from the server filesystem, potentially exposing sensitive system files, configuration data, and credentials.

MitigationApply vendor-supplied patch or upgrade to a patched version of Ilevia EVE X1 Server. As an interim control, implement WAF rules to detect and block path traversal patterns (../, absolute paths) in the db_log parameter and restrict filesystem permissions to limit exposure.

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 the Ilevia EVE X1 Server product
    Locate the device or software running Ilevia EVE X1 Server. Check the product documentation, device label, or admin interface for the exact product name.
    Affected if The product is not Ilevia EVE X1 Server, then this CVE does not apply.
  2. Determine the firmware version
    Access the EVE X1 Server admin panel or use the command-line interface to retrieve the firmware version. Look for a version information page in the settings or run a command such as 'show version' or 'system info' if available.
    Affected if The installed firmware version is 4.7.18.0 or lower, indicating the device is running a vulnerable version.
  3. Verify the web service is accessible
    Confirm that the EVE X1 Server web interface is reachable on the network. Attempt to access the login page or API endpoint over HTTP/HTTPS.
    Affected if The web service is exposed and accessible, which means the vulnerable endpoint could be reached by an attacker.
  4. Inspect the db_log parameter endpoint
    If you have access to the server logs or configuration, locate the endpoint that handles the 'db_log' POST parameter. Review the application configuration or captured network traffic for requests containing this parameter.
    Affected if The application processes the 'db_log' parameter without sanitizing path traversal sequences, making the path traversal vulnerability exploitable.

A system is affected by CVE-2025-34185 if it is an Ilevia EVE X1 Server running firmware version 4.7.18.0 or lower with the web interface accessible and the vulnerable 'db_log' parameter present in the application.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 4.7.18.0
Interim mitigation

Apply vendor-supplied patch or upgrade to a patched version of Ilevia EVE X1 Server. As an interim control, implement WAF rules to detect and block path traversal patterns (../, absolute paths) in the db_log parameter and restrict filesystem permissions to limit exposure.

Recommended fix Moderate confidence

Eve X1 Server Firmware > 4.7.18.0 (e.g., 4.7.19.0 or latest stable release)

  1. Identify the current Eve X1 Server Firmware version running on the affected device
  2. Access the device management interface or use the vendor's firmware update mechanism
  3. Check ilevia's official support portal or firmware repository for available updates
  4. Download and apply firmware version higher than 4.7.18.0 (e.g., 4.7.19.0 or later)
  5. Verify the firmware upgrade was successful and the vulnerability is resolved
  6. Confirm the 'db_log' parameter no longer allows unauthorized file access
Caveat Firmware upgrades may require downtime and could reset device configurations; review release notes for any configuration migration requirements
