CVE-2024-12834 Delta Electronics CVE debrief

Delta Electronics DRASimuCAD contains a type confusion vulnerability that allows specially crafted files to supply incorrect data types during file opening operations. The vulnerability, published on January 9, 2025, and updated on January 16, 2025, affects DRASimuCAD versions 1.02.00.00 and earlier. The CVSS 3.1 score of 7.8 (HIGH) reflects local attack vector with low attack complexity, no privileges required, but user interaction needed. Successful exploitation could result in high impacts to confidentiality, integrity, and availability. Delta Electronics released a patch on January 16, 2025, which requires the base version 1.02.00.00 to be installed first.

Who should care

Organizations using Delta Electronics DRASimuCAD for industrial robot simulation and programming, particularly in manufacturing, automotive, and electronics assembly environments. Security teams responsible for OT/ICS asset protection and engineering workstation hardening should prioritize this patch.

Technical summary

The vulnerability stems from insufficient input validation when DRASimuCAD opens files. The application expects specific data types but fails to properly validate or reject malformed input, accepting data of incorrect types from attacker-controlled files. This type confusion weakness can lead to memory corruption and arbitrary code execution in the context of the application. The attack requires local access with user interaction (opening a malicious file), making it suitable for targeted attacks against engineering workstations through social engineering or compromised file distribution channels.

Defensive priority

HIGH

Recommended defensive actions

  • Apply Delta Electronics patch for DRASimuCAD (requires base version 1.02.00.00 installed first)
  • Avoid opening untrusted DRASimuCAD project files from unknown sources
  • Implement application whitelisting to restrict unauthorized software execution
  • Isolate engineering workstations from business networks and internet exposure
  • Use secure remote access methods (VPN) when remote maintenance is required
  • Review and apply CISA ICS recommended practices for defense-in-depth

Evidence notes

Vulnerability confirmed through CISA ICS advisory ICSA-25-010-03 with vendor acknowledgment. Patch availability confirmed in Update A revision dated 2025-01-16.
