CVE-2024-12835
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 ICS File Parsing Out-Of-Bounds Write 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 ICS files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22415.
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 contains an out-of-bounds write vulnerability in its ICS file parser. The application fails to properly validate user-supplied data during ICS file parsing, allowing an attacker to write past the end of an allocated buffer. Successful exploitation enables arbitrary code execution in the context of the current process.

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 installationSearch for DRASimuCAD in the program files directory or check the Windows registry uninstall key for Delta Electronics softwareAffected if DRASimuCAD is found on the system
-
Determine installed versionRight-click the DRASimuCAD executable, select Properties, and view the Details tab for version information; alternatively, check the About dialog within the applicationAffected if Version displays as 1.02.00.00 or lower
-
Compare version to affected rangeCompare your installed version number to the affected range: any version <= 1.02.00.00 is vulnerableAffected if Installed version is 1.02.00.00 or any earlier release
-
Assess ICS file parser usageIdentify whether the system or users routinely import or open ICS (Industry Foundation Classes) files through DRASimuCAD; check recent file history or default file associationsAffected if ICS file parsing feature is used with untrusted or external ICS files
If DRASimuCAD version 1.02.00.00 or lower is installed and the ICS file parser handles untrusted files, the environment is affected by this vulnerability.

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 dataUntil an official patch is available, users should avoid opening untrusted ICS files or visiting untrusted pages that could deliver malicious ICS content. Organizations should implement network segmentation and apply least-privilege principles to limit exposure.
