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
Generex UPS CS141 below 2.06 version, could allow a remote attacker to upload a firmware file containing a file with modified permissions, allowing him to escalate privileges.

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

Generex UPS CS141 devices below version 2.06 contain a firmware upload vulnerability that fails to properly validate file permissions within uploaded firmware packages. An attacker can upload a malicious firmware file containing executables or scripts with elevated permissions, achieving privilege escalation on the device.

MitigationUpgrade the Generex UPS CS141 firmware to version 2.06 or later, which properly validates file permissions during the firmware upload process.

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
    Locate the UPS device and verify it is a Generex CS141 model. Check device labeling, web interface, or management console for the model number.
    Affected if The device is not a Generex UPS CS141 model, then this CVE does not apply.
  2. Check the installed firmware version
    Access the device web interface, management console, or use SNMP to retrieve the firmware version. Compare the version number against 2.06.
    Affected if The installed firmware version is below 2.06 (e.g., 2.05, 2.04, etc.), indicating the device is vulnerable.
  3. Verify firmware upload functionality is accessible
    Confirm the device web interface or management interface has a firmware upload/update feature available and is accessible to the user or attacker.
    Affected if The firmware upload feature is enabled and accessible, making exploitation possible.
  4. Check for unauthorized firmware files
    Inspect the device file system or backup configurations for any unexpected firmware files or modifications to firmware-related directories.
    Affected if Unexpected firmware files are present that were not authored by the administrator.

The environment is affected if the device is a Generex UPS CS141 running firmware version below 2.06 with the firmware upload feature accessible.

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 2.06 or later
Fixed in 2.06
Interim mitigation

Upgrade the Generex UPS CS141 firmware to version 2.06 or later, which properly validates file permissions during the firmware upload process.

Recommended fix Moderate confidence

Generex CS141 Firmware version 2.06

  1. Obtain the Generex CS141 firmware version 2.06 from the official vendor website (www.generex.de) or authorized distribution channels
  2. Review the vendor's official firmware upgrade documentation for the CS141 device
  3. Upload and apply firmware version 2.06 to the Generex UPS CS141 device following the vendor's documented procedure
  4. Verify the firmware upgrade was successful by checking the device firmware version
  5. Confirm that the device operates normally after the upgrade
Caveat No specific breaking changes documented in the available information; however, as with any firmware upgrade, test in a non-production environment first
