RISK EVALUATION\n\nSuccessful exploitation of these vulnerabilities could cause buffer overflow conditions that may allow information disclosure, remote code execution, or crash the application.\n\n## 3\\. TECHNICAL DETAILS\n\n### 3.1 AFFECTED PRODUCTS\n\nThe following versions of Delta Industrial Automation CNCSoft are affected:\n\n * CNCSoft ScreenEditor Version 1.00.88 and prior\n\n### 3.2 VULNERABILITY OVERVIEW\n\n### 3.2.1 [STACK-BASED BUFFER OVERFLOW CWE-121](<https://cwe.mitre.org/data/definitions/121.html>)\n\nMultiple stack-based buffer overflow vulnerabilities may be exploited by processing specially crafted project files, allowing an attacker to remotely execute arbitrary code. This may occur because CNCSoft lacks user input validation before copying data from project files onto the stack.\n\n[CVE-2019-10947](<http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2019-10947>) has been assigned to these vulnerabilities. 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>)).\n\n### 3.2.2 [HEAP-BASED BUFFER OVERFLOW CWE-122](<https://cwe.mitre.org/data/definitions/122.html>)\n\nMultiple 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.\n\n[CVE-2019-10951](<http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2019-10951>) has been assigned to these vulnerabilities. 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>)).\n\n### 3.2.3 [OUT-OF-BOUNDS READ CWE-125](<https://cwe.mitre.org/data/definitions/125.html>)\n\nMultiple out-of-bounds read vulnerabilities may be exploited, allowing information disclosure due to a lack of user input validation for processing specially crafted project files.\n\n[CVE-2019-10949](<http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2019-10949>) has been assigned to these vulnerabilities. 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](<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:N>)).\n\n### 3.3 BACKGROUND\n\n * **CRITICAL INFRASTRUCTURE SECTORS:** Critical Manufacturing\n * **COUNTRIES/AREAS DEPLOYED: **Worldwide\n * **COMPANY HEADQUARTERS LOCATION: **Taiwan\n\n### 3.4 RESEARCHER\n\nNatnael Samson (@NattiSamson) and an anonymous researcher working with Trend Micro\u2019s Zero Day Initiative (ZDI) reported these vulnerabilities to NCCIC.\n\n## 4\\. MITIGATIONS\n\nDelta recommends the following:\n\n * Update to the latest version of ScreenEditor 1.00.89. This updated version can be found at:\n\n[http://www.deltaww.com/services/DownloadCenter2.aspx?secID=8&amp;pid=2&amp;tid=0&amp;CID=06&amp;itemID=060202&amp;typeID=1&amp;downloadID=&amp;title=&amp;dataType=8;&amp;check=1&amp;hl=en-US ](<http://www.deltaww.com/services/DownloadCenter2.aspx?secID=8&pid=2&tid=0&CID=06&itemID=060202&typeID=1&downloadID=&title=&dataType=8;&check=1&hl=en-US\u00a0>)\n\n * Restrict the interaction with the application to trusted files.\n\nNCCIC recommends users take the following measures to protect themselves from social engineering attacks: \n\n * Do not click web links or open unsolicited attachments in email messages.\n * Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.\n * Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.\n\nNCCIC recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:\n\n * Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.\n * Locate control system networks and remote devices behind firewalls, and isolate them from the business network.\n * When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.\n\nNCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. \n \nNCCIC 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.\n\nAdditional 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. \n \nOrganizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.\n\nNo known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely.\n\n## \nContact Information\n\nFor any questions related to this report, please contact the CISA at: \n \nEmail: [CISAservicedesk@cisa.dhs.gov](<mailto:cisaservicedesk@cisa.dhs.gov>) \nToll Free: 1-888-282-0870\n\nFor industrial control systems cybersecurity information: https://us-cert.cisa.gov/ics \nor incident reporting: https://us-cert.cisa.gov/report\n\nCISA continuously strives to improve its products and services.
