CVE-2018-7245
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 improper authorization 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 change UPS control and shutdown parameters or other critical settings without authorization.
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 confidenceCVE-2018-7245 is an improper authorization vulnerability in the 66074 MGE Network Management Card Transverse web server (ports 80/443 TCP) used in MGE UPS and MGE STS devices. The vulnerability allows remote unauthenticated attackers to modify critical UPS control and shutdown parameters without any authorization, potentially causing service disruption or controlled shutdowns of protected equipment.

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 the MGE Network Management Card on the networkScan your network for devices responding on TCP ports 80 and 443 that identify as MGE Network Management Card or Schneider Electric management interface. Use nmap or network scanner to enumerate open HTTP/HTTPS services.Affected if A device with the 66074 MGE Network Management Card web interface is found accessible on ports 80/443.
-
Confirm the product versionAccess the web interface via HTTP (port 80) or HTTPS (port 443) and look for the firmware version in the web UI footer or in the device information/system status page. The product is the 66074 MGE Network Management Card Transverse.Affected if The device identifies as the 66074 MGE Network Management Card Transverse and shows any firmware version.
-
Test web interface access without credentialsAttempt to access the main management page and navigate to UPS control or shutdown parameters without providing any login credentials. Observe whether the interface loads or returns an authorization error.Affected if The web interface loads and displays UPS management options without requiring authentication.
-
Verify if UPS control parameters are modifiable without authUsing a web request tool (browser or curl), try to submit a request to modify critical UPS parameters such as shutdown settings, output controls, or battery management endpoints without authenticating first.Affected if Parameter modification requests succeed without returning an authentication or authorization error, indicating the vulnerability is present.
-
Check network exposure of the management interfaceDetermine if ports 80/443 are reachable from outside your management network segment. Review firewall rules and determine if the MGE web interface is exposed to untrusted networks or the internet.Affected if The management card web interface is accessible from networks other than a dedicated management VLAN.
You are affected if a 66074 MGE Network Management Card Transverse device is present with its web interface accessible on ports 80/443 and critical UPS parameters can be modified without any 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 dataIsolate affected management cards behind a restricted network segment or firewall, disable remote web access if not operationally essential, and apply any available firmware patches from Schneider Electric. Implement strict network access controls to limit web interface exposure to authorized management networks only.
