CVE-2018-7244
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 · uneditedAn 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Schneider Electric MGE Network Management Card on the networkScan 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' identifiersAffected if A device with these characteristics is found responding on ports 80/443 TCP
-
Verify web server accessibilityAttempt to access http://<device-ip> and https://<device-ip> on ports 80 and 443 respectively using a web browser or curl commandAffected if The web interface loads and is reachable from your network location
-
Confirm information disclosure without authenticationNavigate 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 inAffected if Sensitive device information is returned without requiring login credentials
-
Assess network exposure of the management interfaceReview firewall rules, ACLs, or network segmentation to determine if ports 80/443 are exposed to untrusted networks or the internetAffected 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.

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 dataRestrict 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.
