Vendor: Delta Electronics, Incorporated (Delta Electronics)
Equipment: Delta Industrial Automation Screen Editor
Vulnerabilities: Stack-based Buffer Overflow, Use-after-Free, Out-of-bounds Write, Type Confusion
The following versions of Delta Industrial Automation Screen Editor, a graphical user interface (GUI), are affected:
Successful exploitation of these vulnerabilities may allow an attacker to remotely execute arbitrary code.
Delta Electronics recommends affected users update to the latest version of DOPSoft Version 2, which is available for download at:
http://www.deltaww.com/Products/PluginWebUserControl/downloadCenterCounter.aspx?DID=9313&DocPath=1&hl=en-US.
Delta Industrial Automation Screen Editor Version 2.00.23.00 has been removed from Delta Electronics’ web site and replaced with DOPSoft, Version 2. Delta Electronics also recommends that users restrict the interaction with the application to trusted files.
NCCIC/ICS-CERT recommends that users take the following measures to protect themselves from social engineering attacks:
ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
ICS-CERT 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 in the ICS‑CERT Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not remotely exploitable.
Stack-based buffer overflow vulnerabilities caused by processing specially crafted .dpb files may allow an attacker to remotely execute arbitrary code.
CVE-2017-16751 has been assigned to this vulnerability. A CVSS v3 base score of 5.5 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H).
Specially crafted .dpb files could exploit a use-after-free vulnerability.
CVE-2017-16749 has been assigned to this vulnerability. A CVSS v3 base score of 5.5 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H).
Specially crafted .dpb files may cause the system to write outside the intended buffer area.
CVE-2017-16747 has been assigned to this vulnerability. A CVSS v3 base score of 5.5 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H).
An access of resource using incompatible type (‘type confusion’) vulnerability may allow an attacker to execute remote code when processing specially crafted .dpb files.
CVE-2017-16745 has been assigned to this vulnerability. A CVSS v3 base score of 5.5 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H).
Steven Seeley of Source Incite reported these vulnerabilities to ICS-CERT.
