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
An information disclosure vulnerability exists In Schneider Electric's 66074 MGE Network Management Card Transverse installed in MGE UPS and MGE STS. The integrated web server (Port 80/443/TCP) of the affected devices could allow a remote attacker to obtain sensitive device information if network access was obtained.

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 · moderate confidence

An information disclosure vulnerability in the integrated web server (Port 80/443/TCP) of Schneider Electric's 66074 MGE Network Management Card Transverse allows remote attackers to obtain sensitive device information when network access is obtained. The vulnerability affects MGE UPS and MGE STS devices.

MitigationRestrict network access to the device's web interface using firewall rules or network segmentation. If available, apply vendor firmware updates. Consider disabling external access to ports 80/443 if not required for operations.

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 Schneider Electric MGE Network Management Card on the network
    Scan the network for devices responding to HTTP/HTTPS on ports 80/443 and check the HTTP server banner or HTML title for 'Schneider Electric', 'MGE', 'Network Management Card', or '66074' identifiers
    Affected if A device with these characteristics is found responding on ports 80/443 TCP
  2. Verify web server accessibility
    Attempt to access http://<device-ip> and https://<device-ip> on ports 80 and 443 respectively using a web browser or curl command
    Affected if The web interface loads and is reachable from your network location
  3. Confirm information disclosure without authentication
    Navigate to common paths such as /, /index.html, /status, /network, or /device_info and inspect the response for sensitive data including device configuration, network settings, serial numbers, firmware version, or system uptime without being logged in
    Affected if Sensitive device information is returned without requiring login credentials
  4. Assess network exposure of the management interface
    Review firewall rules, ACLs, or network segmentation to determine if ports 80/443 are exposed to untrusted networks or the internet
    Affected if The web interface on ports 80/443 is accessible from untrusted network segments or the public internet

You are affected if a Schneider Electric 66074 MGE Network Management Card device with its web server accessible on ports 80/443 returns sensitive device information without authentication.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Restrict network access to the device's web interface using firewall rules or network segmentation. If available, apply vendor firmware updates. Consider disabling external access to ports 80/443 if not required for operations.
