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
HGiga PowerStation remote management function has insufficient filtering for user input. An authenticated remote attacker with general user privilege can exploit this vulnerability to inject and execute arbitrary system commands to perform arbitrary system operation or disrupt service.

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

HGiga PowerStation remote management function contains a command injection vulnerability due to insufficient filtering of user input. An authenticated attacker with basic user privileges can inject and execute arbitrary system commands by providing specially crafted input to the management interface.

MitigationImplement strict input validation with whitelist approach, use parameterized system call methods instead of string concatenation, and apply principle of least privilege to the management function.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Confirm HGiga PowerStation product
    Identify the device or software as HGiga PowerStation. Check system information, device model, or installed software name to verify this is the correct product.
    Affected if The product is not HGiga PowerStation, then this CVE does not apply.
  2. Check firmware version
    Access the management interface or use the command: firmware version check command (consult product documentation for specific command or web interface version display). Compare the installed version against x64.6.2.165.
    Affected if Firmware version is below x64.6.2.165.
  3. Verify remote management function is enabled
    Check the product configuration or settings to determine if the remote management function is active. Look for settings related to remote management, web interface access, or administrative access.
    Affected if Remote management function is enabled and accessible over network.
  4. Confirm basic user authentication is possible
    Test login capability with a basic user account (non-administrator) on the management interface. Verify that basic privilege accounts can access the system.
    Affected if Basic user accounts can authenticate to the management interface.
  5. Inspect management interface for command injection vectors
    Review any input fields in the management interface where user-supplied data might be passed to system calls. Look for features that execute system commands based on user input.
    Affected if Input fields in the management interface accept user input that could be passed to system command execution without proper sanitization.

The environment is affected if HGiga PowerStation firmware is below version x64.6.2.165 and the remote management interface is accessible with basic user authentication capabilities.

Mitigation

Implement strict input validation with whitelist approach, use parameterized system call methods instead of string concatenation, and apply principle of least privilege to the management function.

Recommended fix Moderate confidence

x64.6.2.165

  1. Obtain the fixed firmware version x64.6.2.165 or later from HGiga official channels or vendor support
  2. Review HGiga's official firmware upgrade documentation for PowerStation
  3. Apply the firmware upgrade following the vendor's standard update procedure
  4. After upgrade, verify the system is functioning normally
  5. Confirm the version has been updated to x64.6.2.165 or later
