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 · unedited
An attacker who convinces a valid user to open a specially crafted project file to exploit could execute code under the privileges of the application due to an out-of-bounds read vulnerability on the LAquis SCADA (Versions prior to 4.3.1.870).

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 confidence

An out-of-bounds read vulnerability in LAquis SCADA allows remote code execution when a user opens a specially crafted project file. The vulnerability exists in versions prior to 4.3.1.870 and exploits the application's privilege level to execute arbitrary code.

MitigationUpdate LAquis SCADA to version 4.3.1.870 or later. Additionally, implement user awareness training to prevent opening untrusted project files from unverified sources.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify LAquis SCADA installation
    Search for LAquis SCADA executables on the system. Common locations include C:\Program Files\LAquis\ or C:\Program Files (x86)\LAquis\. Look for files named LAquis.exe or similar executables with 'LAquis' in the name.
    Affected if LAquis SCADA is installed and the installed version is lower than 4.3.1.870
  2. Determine installed version
    Right-click the LAquis executable and select Properties, then view the Details tab for version information. Alternatively, right-click the executable, select Properties, and check the Version tab. Compare the File Version or Product Version to 4.3.1.870.
    Affected if The version shown is less than 4.3.1.870 (for example, 4.3.0.500 or any 4.x version prior to 4.3.1.870)
  3. Check for project file handling
    LAquis SCADA uses project files with the .laq extension. Search the system for .laq files in common directories such as Documents folders, project directories, or the application's working directory.
    Affected if The system contains .laq project files, especially from untrusted or external sources, and the application version is below 4.3.1.870

The environment is affected if LAquis SCADA is installed with a version lower than 4.3.1.870 and users can open project files within the application.
