Successful exploitation of these vulnerabilities could allow for remote code execution.
The following versions of DOPSoft, a human machine interface (HMI) editing software, are affected:
3.2.1 STACK-BASED BUFFER OVERFLOW CWE-121
Delta Electronics DOPSoft versions 4.00.16.22 and prior are vulnerable to a stack-based buffer overflow, which could allow an attacker to remotely execute arbitrary code when a malformed file is introduced to the software.
CVE-2023-0123 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).
3.2.2 OUT-OF-BOUNDS WRITE CWE-787
Delta Electronics DOPSoft versions 4.00.16.22 and prior are vulnerable to an out-of-bounds write, which could allow an attacker to remotely execute arbitrary code when a malformed file is introduced to the software.
CVE-2023-0124 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).
Natnael Samson (@NattiSamson), working with Trend Microβs Zero Day Initiative, reported these vulnerabilities to CISA.
Delta Electronics released version 1.3.0 of DIAScreen (login required) and recommends users to use DIAScreen instead of DOPSoft.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
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 at 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.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01BβTargeted 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.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely.
