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
Schrack Technik microControl with firmware before 1.7.0 (937) stores sensitive information under the web root with insufficient access control, which allows remote attackers to obtain access data for the ftp and telnet services via a direct request for ZTPUsrDtls.txt.

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 Schrack Technik microControl device with firmware before 1.7.0 (937) stores user credentials for FTP and telnet services in a plain text file (ZTPUsrDtls.txt) under the web root. This file is accessible without any authentication, allowing remote attackers to directly request the file and obtain valid service credentials.

MitigationUpgrade firmware to version 1.7.0 (937) or later to remediate the improper file placement. Additionally, restrict network access to the device's management interfaces and consider network segmentation.

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 device model
    Access the device's web interface or check the device documentation to confirm it is a Schrack Technik microControl device. Look for model identification in the web UI footer or system information page.
    Affected if The device is a Schrack Technik microControl unit.
  2. Check firmware version
    Navigate to the device's web interface system info or firmware version page. Compare the displayed firmware version against the affected range of <= 1.7.0.
    Affected if The installed firmware version is 1.7.0 or earlier.
  3. Test for vulnerable file access
    Using a web browser or HTTP client, attempt to access the file ZTPUsrDtls.txt at the root of the web server (for example: http://<device_ip>/ZTPUsrDtls.txt).
    Affected if The file downloads or displays without requiring any authentication.
  4. Check if FTP service is enabled
    Check the device configuration pages for FTP service settings, or attempt to connect to the device on TCP port 21 using an FTP client.
    Affected if FTP service is enabled and accessible on the device.
  5. Check if telnet service is enabled
    Check the device configuration pages for telnet service settings, or attempt to connect to the device on TCP port 23 using a telnet client.
    Affected if Telnet service is enabled and accessible on the device.

The device is affected if it is a Schrack Technik microControl with firmware version 1.7.0 or earlier, the file ZTPUsrDtl.txt is accessible without authentication, and FTP or telnet services are enabled.

dbcve · scoped
Upgrade available Upgrade to a release after 1.7.0
Interim mitigation

Upgrade firmware to version 1.7.0 (937) or later to remediate the improper file placement. Additionally, restrict network access to the device's management interfaces and consider network segmentation.

Recommended fix Moderate confidence

Firmware version 1.7.0 (937) or later

  1. Identify the current firmware version of the Schrack Technik microControl device
  2. Access the device administrative interface or use the vendor-provided update mechanism
  3. Locate and download the official firmware version 1.7.0 (937) or later from the vendor
  4. Follow the vendor's documented firmware upgrade procedure, which typically involves uploading the firmware file through the web interface or using a dedicated update tool
  5. Verify the upgrade was successful by checking the firmware version in the administrative interface
  6. Confirm that the ZTPUsrDtls.txt file is no longer accessible via direct HTTP request
Caveat Review vendor release notes for any known compatibility issues or configuration changes required after upgrading
