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
Voltronic Power SNMP Web Pro version 1.1 contains a pre-authentication path traversal vulnerability in the upload.cgi endpoint that allows unauthenticated attackers to read arbitrary files on the device filesystem by supplying directory traversal sequences in the params parameter. Attackers can exploit this vulnerability to disclose sensitive files such as password hashes, which can be cracked offline to obtain root-level access and enable full system compromise.

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

Voltronic Power SNMP Web Pro version 1.1 has a pre-authentication path traversal vulnerability in the upload.cgi endpoint. Attackers can supply directory traversal sequences in the params parameter to read arbitrary files on the device filesystem, potentially exposing sensitive files like password hashes that can be cracked for root access.

MitigationImplement strict input validation on the params parameter to reject directory traversal sequences (../). If no vendor patch is available, restrict network access to the web interface via firewall or disable the service if not required.

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. Check Wpdiscuz plugin version
    Navigate to WordPress admin dashboard > Plugins > Wpdiscuz, or inspect the plugin file /wp-content/plugins/wpdiscuz/wpdiscuz.php and look for the 'Version' header comment
    Affected if The installed version is less than 7.6.47 (e.g., 7.6.0, 7.5.x, etc.)
  2. Verify upload functionality is accessible
    Check if the wpdiscuz upload functionality is enabled in the plugin settings under Comments > Settings > General > Enable Wpdiscuz
    Affected if The upload feature is enabled and the web server is publicly accessible
  3. Inspect HTTP requests to upload endpoint
    Use browser developer tools or a proxy to examine network requests when posting a comment with file attachment, looking for the upload endpoint path
    Affected if Requests are sent to an endpoint without authentication required

You are affected if the Wpdiscuz plugin version installed is below 7.6.47 and the upload functionality is accessible to unauthenticated users.
