CVE-2024-47131
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 · uneditedIf an attacker tricks a valid user into running Delta Electronics DIAScreen with a file containing malicious code, a stack-based buffer overflow in BACnetObjectInfo can be exploited, allowing the attacker to remotely execute arbitrary code.
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 confidenceA stack-based buffer overflow vulnerability exists in the BACnetObjectInfo component of Delta Electronics DIAScreen. An attacker can exploit this by tricking a valid user into opening a malicious file with the application, leading to 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.
-
Verify DIAScreen installationCheck for DIAScreen installation by looking in common program directories (C:\Program Files\Delta Electronics\DIAScreen or C:\Program Files (x86)\Delta Electronics\DIAScreen) or search for the executable file named DIAScreen.exeAffected if DIAScreen is installed on the system
-
Find installed versionRight-click on DIAScreen.exe, select Properties, and check the Details tab for the version number. Alternatively, open DIAScreen and look in the Help > About menu for version informationAffected if The version shown is below 1.5.0 (for example, 1.4.x, 1.3.x, etc.)
-
Confirm BACnetObjectInfo component presenceWithin DIAScreen, navigate to the BACnet configuration or object information features. This component is part of the core DIAScreen application for BACnet protocol communicationAffected if The BACnetObjectInfo or BACnet object browser functionality is accessible and operational in the installed version
-
Check for recent suspicious file openingsReview recent file access logs or the application's recent files list to see if untrusted or unexpected .dcf, .dia, or other DIAScreen project files were recently openedAffected if There are records of opening files from untrusted or unknown sources, especially if combined with version < 1.5.0
The system is affected if Delta Electronics DIAScreen is installed and the installed version is any release prior to 1.5.0, since the vulnerability exists in the BACnetObjectInfo component regardless of configuration.

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.
dbcve · scoped1.5.0
Organizations should update to any available vendor patch when released. Until then, enforce strict policies against opening untrusted files and provide user awareness training to prevent social engineering attacks.
1.5.0
- Obtain DIAScreen version 1.5.0 or later from the official Delta Electronics website (deltaww.com) or through CISA ICS CERT advisories
- Verify the integrity of the downloaded installer using checksums if provided by the vendor
- Uninstall the current vulnerable version of DIAScreen from the affected system
- Install the updated DIAScreen version 1.5.0 or later
- Restart any services or applications that use DIAScreen if necessary
