RISK EVALUATION\n\nSuccessful exploitation of these vulnerabilities could allow an administrator account login without password authentication and remote code execution with root privileges.\n\n## 3\\. TECHNICAL DETAILS\n\n### 3.1 AFFECTED PRODUCTS\n\nThe following versions of WebHMI, a SCADA system with built-in web server capability, are affected:\n\n * All versions prior to 4.1\n\n### 3.2 VULNERABILITY OVERVIEW\n\n#### 3.2.1 [AUTHENTICATION BYPASS BY PRIMARY WEAKNESS CWE-305](<https://cwe.mitre.org/data/definitions/305.html>)\n\nThe authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness primary to the authentication error.\n\n[CVE-2021-43931](<http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-43931>) has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is ([AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H](<https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H>)).\n\n#### 3.2.2 [UNRESTRICTED UPLOAD OF FILE WITH DANGEROUS TYPE CWE-434](<https://cwe.mitre.org/data/definitions/434.html>)\n\nThe software allows the attacker to upload or transfer files of dangerous types that can be automatically processed within the product\u2019s environment or lead to arbitrary code execution.\n\n[CVE-2021-43936](<http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-43936>) has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is ([AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H](<https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H>)).\n\n### 3.3 BACKGROUND\n\n * **CRITICAL INFRASTRUCTURE SECTORS: **Critical Manufacturing\n * **COUNTRIES/AREAS DEPLOYED:** Germany, Poland, Ukraine, United States\n * **COMPANY HEADQUARTERS LOCATION:** Ukraine\n\n### 3.4 RESEARCHER\n\nMarcin Dudek of CERT.PL reported these vulnerabilities to CISA.\n\n## 4\\. MITIGATIONS\n\nDistributed Data Systems recommends:\n\n * Upgrading the platform software to the latest release, [Version 4.1](<http://webhmi.com.ua/en/2021/09/new-webhmi-firmware-release-4-1/>)\n\nCISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. 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](<https://us-cert.cisa.gov/ics/alerts/ICS-ALERT-10-301-01>).\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 VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as its connected devices.\n\nCISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. \n \nCISA also provides a section for [control systems security recommended practices](<https://us-cert.cisa.gov/ics/recommended-practices>) on the ICS webpage on [us-cert.cisa.gov](<https://us-cert.cisa.gov/ics>). Several recommended practices are available for reading and download, including [Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies](<https://us-cert.cisa.gov/sites/default/files/recommended_practices/NCCIC_ICS-CERT_Defense_in_Depth_2016_S508C.pdf>).\n\nAdditional mitigation guidance and recommended practices are publicly available on the [ICS webpage on us-cert.cisa.gov](<https://us-cert.cisa.gov/ics>) in the Technical Information Paper, [ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies](<https://us-cert.cisa.gov/ics/tips/ICS-TIP-12-146-01B>). \n \nOrganizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.\n\nNo known public exploits specifically target these vulnerabilities.\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.
