3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of DRASimuCAD, a robotic simulation platform, are affected: DRASimuCAD : Version 1.02 3.2 Vulnerability 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). 3.2.1 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-2024-12836 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). 3.3 BACKGROUND CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing COUNTRIES/AREAS DEPLOYED: Worldwide COMPANY HEADQUARTERS LOCATION: Taiwan 3.4 RESEARCHER rgod working with Trend Micro Zero Day Initiative reported these vulnerabilities to CISA.
