CVE-2024-12834
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 · uneditedDelta Electronics DRASimuCAD STP File Parsing Type Confusion Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Delta Electronics DRASimuCAD. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of STP files. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22414.
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 confidenceDelta Electronics DRASimuCAD contains a type confusion vulnerability in its STP file parsing logic. The lack of proper validation of user-supplied data during STP file parsing allows an attacker to trigger a type confusion condition, enabling arbitrary code execution in the context of the current process. Exploitation requires user interaction—specifically opening a maliciously crafted STP file.

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 DRASimuCAD is installedCheck for DRASimuCAD in installed programs via Control Panel > Programs and Features, or search for 'DRASimuCAD' in the Start menu or program files directory.Affected if The software is present on the system
-
Identify installed DRASimuCAD versionOpen DRASimuCAD and navigate to Help > About, or right-click the executable in the installation folder and select Properties > Details to view the version number.Affected if The version is 1.02.00.00 or lower
-
Locate STP file handling componentSearch for files related to STP parsing within the DRASimuCAD installation directory, typically found under C:\Program Files\Delta Electronics\DRASimuCAD or similar path.Affected if STP parsing modules or libraries are present in the installation folder
-
Check for recent STP file activityReview the application's recent files list or Windows recent documents for any opened .stp files, or check the application logs if available.Affected if STP files have been opened recently using the software
-
Inspect application for unexpected behaviorMonitor DRASimuCAD process for unusual network connections or spawning of unexpected child processes using Task Manager or Process Explorer.Affected if The application exhibits anomalous behavior such as unauthorized process creation or unusual network activity
A system is affected if DRASimuCAD version 1.02.00.00 or lower is installed and has been used to open STP files from untrusted sources.

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 dataAvoid opening STP files from untrusted or unknown sources. Apply vendor patches when available to address the lack of proper input validation in STP file parsing.
