CVE-2024-39605
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 BACnetParameter 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 confidenceStack-based buffer overflow in the BACnetParameter component of Delta Electronics DIAScreen allows remote code execution when a user is tricked into opening a malicious file. The vulnerability requires user interaction (opening a crafted file) but can result in full remote code execution on the affected system.

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 in the system by searching for the application in installed programs (Windows: Add/Remove Programs, Programs and Features; or check common installation directories such as C:\Program Files\Delta Electronics\DIAScreen or C:\Program Files (x86)\Delta Electronics\DIAScreen)Affected if DIAScreen is present on the system
-
Determine installed versionRight-click the DIAScreen executable (commonly named DIAScreen.exe or similar), select Properties, and view the Details tab for version information; alternatively, open DIAScreen and check Help > About for the version numberAffected if The displayed version is lower than 1.5.0 (for example, 1.4.x, 1.3.x, etc.)
-
Confirm vulnerability trigger conditionThe vulnerability resides in the BACnetParameter component and is triggered when a user opens a maliciously crafted file with DIAScreen; verify if the BACnetParameter functionality is accessible or commonly used in your workflowsAffected if Users open .dcf, .dia, or other DIAScreen project files from untrusted sources, or the BACnetParameter feature is used to load external files
The system is affected if Delta Electronics DIAScreen is installed with a version lower than 1.5.0 and users open untrusted files with the application.

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
Users should avoid opening untrusted files with DIAScreen until a vendor patch is available. Implement application whitelisting and user awareness training to reduce the risk of social engineering attacks leveraging this vulnerability.
1.5.0 or later
- Obtain DIAScreen version 1.5.0 or later from the official Delta Electronics website (www.deltaww.com) or CISA ICS-advisory resources
- Ensure all running instances of DIAScreen are closed before upgrading
- Install the updated DIAScreen version 1.5.0 or later following standard installation procedures
- Verify the installed version is 1.5.0 or higher after installation completes
