EXECUTIVE SUMMARY * **CVSS v3 7.8** * **ATTENTION:** Low skill level to exploit * **Vendor:** Delta Electronics * **Equipment:** Delta Industrial Automation DOPSoft * **Vulnerabilities:** Out-of-bounds Read, Heap-based Buffer Overflow ## 2\. UPDATE INFORMATION This updated advisory is a follow-up to the original advisory titled ICSA-20-182-01 Delta Industrial Automation DOPSoft that was published June 30, 2020, on the ICS webpage on us-cert.gov. ## 3\. RISK EVALUATION Successful exploitation of these vulnerabilities could allow an attacker to read/modify information, execute arbitrary code, and/or crash the application. ## 4\. TECHNICAL DETAILS ### 4.1 AFFECTED PRODUCTS The following versions of DOPSoft, a Human Machine Interface (HMI) editing software, are affected: * DOPSoft Version 4.00.08.15 and prior ### 4.2 VULNERABILITY OVERVIEW #### 4.2.1 [OUT-OF-BOUNDS READ CWE-125](https://cwe.mitre.org/data/definitions/125.html) Multiple out-of-bounds read vulnerabilities may be exploited by processing specially crafted project files, which may allow an attacker to read information and/or crash the application. [CVE-2020-10597](http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-10597) has been assigned to this vulnerability. A CVSS v3 base score of 4.4 has been calculated; the CVSS vector string is ([AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L)). #### 4.2.2 [HEAP-BASED BUFFER OVERFLOW CWE-122](https://cwe.mitre.org/data/definitions/122.html) Opening a specially crafted project file may overflow the heap, which may allow remote code execution, disclosure/modification of information, or cause the application to crash. [CVE-2020-14482](http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-14482) has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is ([AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)). ### 4.3 BACKGROUND * **CRITICAL INFRASTRUCTURE SECTORS:** Critical Manufacturing * **COUNTRIES/AREAS DEPLOYED:** Worldwide * **COMPANY HEADQUARTERS LOCATION:** Taiwan ### 4.4 RESEARCHER Natnael Samson (@NattiSamson), working with Trend Micro's Zero Day Initiative, reported these vulnerabilities to CISA. ## 5\.
