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 · uneditedNETGEAR MR1100 devices before 12.06.08.00 are affected by disclosure of administrative credentials.
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 confidenceNETGEAR MR1100 mobile hotspot devices before firmware version 12.06.08.00 contain a vulnerability that allows disclosure of administrative credentials. This information disclosure issue could allow an attacker with appropriate access to obtain credentials used for administrative authentication on the device.

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.
-
Confirm device model is NETGEAR MR1100Access the device administrative interface or check the device label to verify the exact model number is NETGEAR MR1100Affected if Device is not a NETGEAR MR1100 model
-
Locate firmware version informationAccess the device administrative interface and navigate to the firmware or status page to view the currently installed firmware versionAffected if Unable to retrieve firmware version information from the device
-
Compare installed version against affected rangeIdentify the firmware version string displayed in the device interface and compare it numerically to version 12.06.08.00Affected if Installed firmware version is less than 12.06.08.00 (for example, 12.06.07.00 or earlier)
-
Assess exposure of device management interfaceDetermine if the device administrative interface is accessible from untrusted networks or if it has been exposed to the internetAffected if Device management interface is accessible from networks outside your trusted administrative environment
You are affected if your NETGEAR MR1100 device is running firmware version earlier than 12.06.08.00 and the management interface could be accessed by an attacker.

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 data12.06.08.00
Update NETGEAR MR1100 firmware to version 12.06.08.00 or later. If immediate updating is not possible, change all administrative passwords, restrict network access to the device management interface, and monitor for unauthorized access attempts.
