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 webshell that could allow him to execute arbitrary code as root.

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 Generex UPS CS141 device versions below 2.06 contain an insecure firmware upload mechanism that lacks proper validation of uploaded firmware files. An attacker can craft a malicious firmware package containing a webshell and upload it to the device, then execute the webshell to achieve arbitrary code execution with root privileges.

MitigationUpgrade the Generex UPS CS141 firmware to version 2.06 or later to remediate this vulnerability. If upgrading is not immediately possible, restrict network access to the device's management interface and disable any unnecessary remote access features.

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 confirm it is a Generex CS141 model by checking the device label, management interface, or SNMP inventory
    Affected if The device is a Generex CS141 unit
  2. Determine the installed firmware version
    Access the device's web management interface or use SNMP to query the firmware version information. Look for a version field in the system info or status page
    Affected if The displayed firmware version is below 2.06 (e.g., 2.05, 2.04, etc.)
  3. Verify if the web management interface is accessible
    Attempt to reach the device's HTTP/HTTPS management portal from a network location. Check if port 80 or 443 (or configured alternative ports) respond
    Affected if The management interface is reachable over the network and accepts authentication
  4. Confirm firmware upload functionality is present
    Log into the device management interface and navigate to firmware update, upgrade, or maintenance sections. Look for a firmware upload or file import feature
    Affected if A firmware upload or upgrade page exists and accepts file uploads

A user is affected if they have a Generex CS141 device running firmware version 2.05 or lower, with the device's web management interface accessible and the firmware upload feature available.

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 to remediate this vulnerability. If upgrading is not immediately possible, restrict network access to the device's management interface and disable any unnecessary remote access features.

Recommended fix Moderate confidence

Firmware version 2.06

  1. 1. Visit the official Generex support website at www.generex.de to obtain the firmware version 2.06 or later for the CS141 device.
  2. 2. Review the device's current firmware version through the administrative web interface or console.
  3. 3. Create a backup of the current device configuration if the web interface provides export functionality.
  4. 4. Access the firmware update section in the device's administrative interface.
  5. 5. Upload the downloaded firmware file (version 2.06 or later) to the device.
  6. 6. Wait for the firmware upload and installation process to complete; do not power off the device during this process.
  7. 7. After the device reboots, verify that the new firmware version (2.06) is installed.
  8. 8. Confirm that the device is functioning normally and all services are operational.
