CVE-2018-18992
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 · uneditedLCDS Laquis SCADA prior to version 4.1.0.4150 allows taking in user input without proper sanitation, which may allow an attacker to execute remote code on the server.
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 confidenceLCDS Laquis SCADA prior to version 4.1.0.4150 contains an input validation vulnerability where user-supplied data is processed without proper sanitization, potentially allowing remote code execution on the server through injection of malicious commands.

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.
-
Locate the installed Laquis SCADA versionCheck the Laquis SCADA installation directory for version information files, or access the About/Version section within the SCADA application interface. Common locations include the main executable properties, an About dialog, or a version.txt file in the installation folder.Affected if The displayed version number is lower than 4.1.0.4150, indicating the installation is prior to the patched release.
-
Verify the SCADA server is runningCheck if the Laquis SCADA server service or process is active. This may be visible in Windows Task Manager, Services panel, or by checking if the SCADA listening ports (commonly TCP ports associated with Laquis) are in an open state using netstat or a port scanner.Affected if The server is running and accepting remote connections, creating a potential attack surface for the input validation flaw.
-
Inspect network exposure of the SCADA interfaceReview firewall rules, router configurations, or network ACLs to determine if the Laquis SCADA web or server interface is accessible from untrusted networks. Use netstat -an or similar tools to identify listening IPs and ports.Affected if The SCADA interface is bound to 0.0.0.0 or an external IP address rather than localhost or a trusted internal network, increasing exposure to remote exploitation.
-
Review input handling configurationExamine the SCADA project configuration files or server settings for any exposed input entry points such as web interfaces, API endpoints, or data import features that accept user-supplied data without apparent validation.Affected if The SCADA system exposes input channels (web forms, data import, remote commands) that process user data without documented sanitization, indicating the vulnerable configuration may be present.
If the installed Laquis SCADA version is lower than 4.1.0.4150 AND the SCADA server interface is network-accessible, the environment is likely affected by this input validation vulnerability.

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 data4.1.0.4150
Upgrade Laquis SCADA to version 4.1.0.4150 or later. If upgrading is not immediately feasible, implement input validation and sanitization at all entry points and restrict network access to the SCADA interface.
