CVE-2018-15360
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 attacker without authentication can login with default credentials for privileged users in Eltex ESP-200 firmware version 1.2.0.
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 confidenceThe Eltex ESP-200 firmware version 1.2.0 contains hardcoded default credentials for privileged administrative accounts that can be exploited by any unauthenticated attacker to gain full administrative access to 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.
-
Identify the device modelAccess the device web interface or check the physical device label to confirm it is an Eltex ESP-200. Look for 'ESP-200' or 'Eltex' markings on the device chassis or in the administrative interface.Affected if The device is an Eltex ESP-200
-
Check the installed firmware versionLog into the device administrative interface and navigate to the Status or System Information page to view the firmware version. Alternatively, check the boot log or use SNMP to query the device firmware version.Affected if The firmware version is exactly 1.2.0
-
Verify default credentials statusCheck if the administrative accounts are using the factory-default usernames and passwords. Review any documentation or configuration backups for account settings. Compare against known default credential patterns for this device.Affected if Default administrative credentials have not been changed from factory settings
-
Review for unauthorized administrative accessExamine device logs, authentication logs, or audit trails for any administrative logins from unknown IP addresses or at unusual times. Check for multiple failed login attempts followed by successful administrative access.Affected if There are signs of unauthorized administrative access that did not originate from legitimate administrators
If the device is an Eltex ESP-200 running firmware version 1.2.0 and the default credentials remain unchanged, the device is affected by CVE-2018-15360.

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 dataImmediately change all default credentials to strong, unique passwords; disable remote administrative access if not required; contact vendor for patched firmware and apply available updates.
