3.2 VUNERABILITY OVERVIEW
3.2.1 Access of Resource Using Incompatible Type ('Type Confusion') CWE-843
Delta Electronics DRASimuCAD expects a specific data type when it opens files, but the program will accept data of the wrong type from specially crafted files.
CVE-2024-12834 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2024-12834. A base score of 8.4 has been calculated; the CVSS vector string is (CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).
3.2.2 Out-of-bounds Write CWE-787
When a specially crafted file is opened with Delta Electronics DRASimuCAD, the program can be forced to write data outside of the intended buffer.
CVE-2024-12835 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2024-12835. A base score of 8.4 has been calculated; the CVSS vector string is (CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).
3.2.3 Access of Resource Using Incompatible Type ('Type Confusion') CWE-843
Delta Electronics DRASimuCAD expects a specific data type when it opens files, but the program will accept data of the wrong type from specially crafted files.
CVE-2024-12836 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2024-12836. A base score of 8.4 has been calculated; the CVSS vector string is (CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

4. MITIGATIONS
Delta has released a patch to fix these vulnerabilities on Delta Download Center. This patch is based on the formal DRASimuCAD v1.02.00.00. Users should have the original v1.02.00.00 installed, then install this new patch.
Delta also recommends the following general security practices:
- Don't click on untrusted Internet links or open unsolicited attachments in emails.
- Avoid exposing control systems and equipment to the Internet.
- Place systems and devices behind a firewall and isolate them from the business network.
- When remote access is required, use a secure access method, such as a virtual private network (VPN).
For more information, please see the Delta product cybersecurity advisory for these issues.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time. These vulnerabilities are not exploitable remotely.
