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.
Successful exploitation of these vulnerabilities could allow an attacker to read/modify information, execute arbitrary code, and/or crash the application.
The following versions of DOPSoft, a Human Machine Interface (HMI) editing software, are affected:
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 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).
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 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).
