Successful exploitation of these vulnerabilities could cause buffer overflow conditions that may allow information disclosure, remote code execution, or crash the application.
According to Delta Electronics, the following versions are affected:
Multiple heap-based buffer overflow vulnerabilities may be exploited by processing specially crafted project files, allowing an attacker to remotely execute arbitrary code. There is a lack of user input validation before copying data from project files onto the heap.
CVE-2019-10982 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).
Multiple out-of-bounds read vulnerabilities may cause information disclosure due to lacking user input validation for processing project files.
CVE-2019-10992 has been assigned to this vulnerability. A CVSS v3 base score of 3.3 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N).
Natnael Samson (@NattiSamson) working with Trend Micro Zero Day Initiative (ZDI) reported these vulnerabilities to NCCIC.
Delta Electronics recommends the following:
NCCIC recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:
NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
NCCIC also provides a section for control systems security recommended practices on the ICS-CERT web page. Several recommended 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-CERT website in the Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.
NCCIC also recommends that users take the following measures to protect themselves from social engineering attacks:
No known public exploits specifically target these vulnerabilities.
