CVE-2024-12836
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-22450.
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 confidenceDelta Electronics DRASimuCAD suffers from a type confusion vulnerability in its STP file parser due to insufficient validation of user-supplied data. An attacker can craft a malicious STP file that triggers the type confusion, allowing execution of arbitrary code in the context of the current process when the victim opens the 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.
-
Identify DRASimuCAD installationLocate the DRASimuCAD application on the system. Check Program Files, Program Files (x86), or the installation directory used during setup. Look for executable files named Drasimucad.exe or similar.Affected if The application is installed and the version is at or below 1.02.00.00
-
Determine installed versionRight-click the executable, select Properties, and view the File Version or Product Version field. Alternatively, open the application and check Help > About or the application's main window for version information.Affected if The reported version number is 1.02.00.00 or lower, placing it within the affected range
-
Verify STP file handling capabilityAttempt to open or import an STP file within DRASimuCAD, or check the application's file open dialog for STP file type support. Confirm the STP parser functionality is present.Affected if The application can open, import, or process STP files, enabling the vulnerable parser
-
Inspect recent file activityCheck the application's recent files list, Windows Jump List, or file system for recently accessed .stp files. Examine browser download folders and common document locations for STP files.Affected if There are unknown or unexpected STP files that may have been opened, especially from untrusted sources
A user is affected if DRASimuCAD version 1.02.00.00 or lower is installed and the application has the ability to process STP files, as the type confusion vulnerability triggers upon opening a maliciously crafted STP file.

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 dataApply the vendor patch when available. Until then, exercise caution with STP files from untrusted sources and consider restricting file handling in DRASimuCAD or using endpoint protection to block malicious file types.
