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
MOMA Seismic Station Version v2.4.2520 and prior exposes its web management interface without requiring authentication, which could allow an unauthenticated attacker to modify configuration settings, acquire device data or remotely reset the device.

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 MOMA Seismic Station web management interface (versions v2.4.2520 and prior) lacks authentication controls, allowing any unauthenticated remote attacker to access the administrative interface and perform critical actions including modifying configuration settings, extracting device data, and remotely resetting the device.

MitigationIsolate the device behind a firewall or VPN to restrict network access, and contact the vendor for a patched firmware version that implements proper authentication on the web interface.

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 MOMA Seismic Station in your environment
    Inventory your network devices and look for MOMA Seismic Station web management interfaces. Check device documentation or network scans for this specific product.
    Affected if If MOMA Seismic Station devices are present in your network
  2. Determine the web interface version
    Access the web management interface and check the firmware/software version displayed in the admin panel, or use a banner-grabbing tool to retrieve version information from the HTTP response headers.
    Affected if If the version is v2.4.2520 or prior
  3. Verify if web interface is network accessible
    Scan your network for exposed HTTP/HTTPS ports associated with MOMA Seismic Station devices. Check if the interface is accessible from untrusted networks.
    Affected if If the interface is exposed to network segments without proper access controls
  4. Test authentication enforcement on the admin interface
    Attempt to access administrative paths (such as /admin, /settings, or configuration endpoints) without providing credentials. Observe whether the interface grants access to admin functions without a login prompt.
    Affected if If unauthenticated access to admin functions is possible

Your environment is affected if you have MOMA Seismic Station devices running firmware v2.4.2520 or prior with the web management interface exposed to network access without proper authentication controls.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Isolate the device behind a firewall or VPN to restrict network access, and contact the vendor for a patched firmware version that implements proper authentication on the web interface.
