CVE-2024-12836 is a remote code execution vulnerability identified in Delta Electronics DRASimuCAD version 1.02, specifically within the STP file parsing functionality. The root cause is a type confusion condition (CWE-843), where the software incorrectly handles user-supplied data types during the parsing process. This flaw allows an attacker to craft malicious STP files that, when opened by a user, trigger the vulnerability and enable arbitrary code execution under the privileges of the DRASimuCAD process. Exploitation requires user interaction, such as opening a malicious file or visiting a malicious webpage that causes the application to parse the crafted STP file. The vulnerability does not require prior authentication and has a CVSS 3.0 base score of 7.8, indicating high severity with high impact on confidentiality, integrity, and availability. The attack vector is local (AV:L), meaning the attacker must have local access or trick the user into opening the malicious file. The vulnerability was reported by the Zero Day Initiative (ZDI) under ID ZDI-CAN-22450 and was publicly disclosed on December 30, 2024. No patches or known exploits are currently available, but the potential for remote code execution makes this a critical concern for organizations relying on DRASimuCAD for industrial automation and simulation tasks.

The exploitation of CVE-2024-12836 can lead to full compromise of the affected system running DRASimuCAD, allowing attackers to execute arbitrary code with the same privileges as the application. This can result in unauthorized access to sensitive industrial design data, manipulation or destruction of simulation models, and potential disruption of industrial automation workflows. The confidentiality of proprietary designs and intellectual property is at risk, as is the integrity of simulation results critical for manufacturing processes. Availability may also be impacted if the attacker disrupts or disables the application. Given DRASimuCAD's role in industrial environments, successful exploitation could have downstream effects on production lines and operational technology systems, potentially causing financial losses and safety hazards. The requirement for user interaction limits the attack surface but does not eliminate risk, especially in environments where users may open files from untrusted sources.

1. Immediately restrict access to DRASimuCAD version 1.02 installations and avoid opening STP files from untrusted or unknown sources. 2. Implement strict file validation and sandboxing measures to isolate the application and limit the impact of potential exploits. 3. Educate users on the risks of opening unsolicited or suspicious STP files and visiting untrusted websites. 4. Monitor network and endpoint activity for unusual behavior indicative of exploitation attempts, such as unexpected process executions or file modifications. 5. Coordinate with Delta Electronics for timely release and deployment of official patches or updates addressing this vulnerability. 6. Employ application whitelisting and endpoint detection and response (EDR) solutions to detect and block malicious payloads. 7. Use network segmentation to isolate systems running DRASimuCAD from critical operational technology networks to reduce lateral movement risk. 8. Regularly back up critical simulation data and configurations to enable recovery in case of compromise.
