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
The image file management page of SolarView Compact SV-CPT-MC310 Ver.7.23 and earlier, and SV-CPT-MC310F Ver.7.23 and earlier contains an insufficient verification vulnerability when uploading files. If this vulnerability is exploited, arbitrary PHP code may be executed if a remote authenticated attacker uploads a specially crafted PHP file.

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 image file management page of SolarView Compact SV-CPT-MC310 (versions 7.23 and earlier) lacks proper file validation during upload, allowing authenticated attackers to upload arbitrary PHP files. This insufficient verification of uploaded files enables remote code execution when the uploaded PHP is accessed.

MitigationImplement strict file upload validation: whitelist allowed file extensions and MIME types, verify file magic bytes/content, rename uploaded files, and store them outside the web root. Update to version 7.30 or later which patches this vulnerability.

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 firmware version
    Access the device web interface or check system information page. Look for firmware version displayed in the admin panel or system status section.
    Affected if The displayed firmware version is 7.23 or earlier, or any version below 7.24.
  2. Confirm image file management feature exists
    Navigate to the image file management page within the web interface. This is typically found under maintenance, settings, or upload sections of the admin panel.
    Affected if The image file management upload page is present and accessible after authentication.
  3. Verify web interface accessibility
    Attempt to access the SolarView Compact administration interface via HTTP/HTTPS on the device IP address.
    Affected if The web administrative interface is reachable on the network.
  4. Check authentication status
    Determine whether default credentials are in use or if any valid user account exists on the system.
    Affected if Any valid credentials can be obtained or default credentials are still active, allowing login to the image file management page.

You are affected if your device runs firmware version 7.23 or earlier (below 7.24) and the image file management upload feature is accessible after authentication.
