CVE-2018-14826
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 · uneditedEntes EMG12 versions 2.57 and prior The application uses a web interface where it is possible for an attacker to bypass authentication with a specially crafted URL. This could allow for remote code execution.
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 confidenceThe Entes EMG12 industrial controller web interface versions 2.57 and prior contains an authentication bypass vulnerability where specially crafted URLs can allow attackers to circumvent authentication mechanisms and achieve remote code execution.

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 Entes EMG12 device in networkLocate Entes EMG12 industrial controllers on the network by checking device documentation, network scans for unique HTTP service banners, or physical device identification. Note the IP addresses where the web interface is accessible.Affected if Entes EMG12 controller is present on the network with an accessible web interface.
-
Access the web interface version informationOpen a web browser to the EMG12 device IP address and navigate to the login page, About page, or system information page typically found under Settings, System, or Help menus. Note the firmware version displayed.Affected if Firmware version 2.57 or lower is displayed on the web interface.
-
Verify firmware version via diagnostic interfaceIf the web interface version is not visible, attempt to access the firmware version via CLI or serial console连接到设备，or check the firmware file name if obtained from vendor downloads.Affected if The diagnostic or firmware source shows version 2.57 or prior.
-
Assess web interface accessibilityDetermine if the EMG12 web interface is exposed to untrusted networks by reviewing firewall rules, VLAN configurations, and access control lists. Verify whether it is accessible from the internet or only from trusted internal networks.Affected if The web interface is accessible from untrusted networks or the internet without IP-based access restrictions.
The environment is affected if an Entes EMG12 controller with firmware version 2.57 or lower has its web interface accessible, since the authentication bypass requires the vulnerable web service to be reachable.

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 restrict web interface exposure via network segmentation, disable remote access if not required, and contact vendor for patched firmware. If patching is unavailable, implement compensating controls such as firewall rules limiting access to trusted IPs only.
