CVE-2024-5040
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 · uneditedThere are multiple ways in LCDS LAquis SCADA for an attacker to access locations outside of their own directory.
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 contains a path traversal vulnerability allowing authenticated or unauthenticated attackers to escape their designated directory and access files outside their allowed scope. This is a directory traversal issue where the application fails to properly validate file paths, enabling access to sensitive system files.

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 LAquis SCADA installationLocate the LAquis SCADA application directory. Common paths include C:\LAquis or C:\Program Files\LAquis. Check for the presence of laquis.exe or related SCADA application files.Affected if The LAquis SCADA application is installed on the system
-
Identify web interface or file service componentCheck if the LAquis SCADA web server or file serving component is running. Look for processes listening on common web ports (80, 443, 8080) or check LAquis configuration for web service enablement.Affected if The web or file serving interface is enabled and exposed
-
Verify authentication controls on file operationsReview LAquis configuration files (typically in the application directory with .xml, .ini, or .cfg extensions) for file upload/download or directory listing features. Check if these endpoints permit unauthenticated access.Affected if File access features do not require authentication or have weak access controls
-
Test for directory traversal in file pathsIf a web interface exists, attempt to access files outside the intended directory using path traversal sequences such as ../ or ..\ in file request parameters. Observe if the application returns files from parent directories.Affected if The application returns files from directories outside the intended scope when traversal sequences are used
-
Check for recent access logs indicating traversal attemptsReview LAquis web server logs or application logs for unusual patterns containing ../ sequences or access to system files (e.g., ../../windows/system32/config).Affected if Logs show directory traversal patterns or unauthorized file access attempts
A system is affected if LAquis SCADA is installed with its file serving or web interface enabled, and the application allows path traversal to access files outside the designated directory without proper validation.

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 dataImplement strict input validation with canonicalization of file paths, restrict file access to allowed directories using allowlists, and ensure proper authentication and authorization checks are enforced on all file access operations.
