A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is ([AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H](<https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H>)).\n\n### 4.3 BACKGROUND\n\n * **CRITICAL INFRASTRUCTURE SECTORS: **Chemical, Energy, Food and Agriculture, Healthcare and Public Health, Transportation Systems, and Water and Wastewater Systems\n * **COUNTRIES/AREAS DEPLOYED: **Worldwide\n * **COMPANY HEADQUARTERS LOCATION: **Germany\n\n### 4.4 RESEARCHER\n\nSiemens reported these vulnerabilities to CISA.\n\n## 5\\. MITIGATIONS\n\n**\\--------- Begin Update B Part 2 of 2 ---------**\n\nSiemens recommends upgrading SCALANCE W1750D to [v8.7.1.3 or later](<https://support.industry.siemens.com/cs/de/en/view/109802805/>)\n\n**\\--------- End Update B Part 2 of 2 ---------**\n\nSiemens has identified the following specific workarounds and mitigations for users to apply to reduce the risk:\n\n * Block access to the Aruba Instant device IP address on Port 8211/UDP from all untrusted users.\n * Block access to the Aruba Instant Command Line Interface from all untrusted users.\n * Block access to the Aruba Instant Web Management Interface from all untrusted users.\n\nAs a general security measure, Siemens strongly recommends protecting network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends configuring the environment according to [Siemens\u2019 operational guidelines for industrial security](<https://cert-portal.siemens.com/operational-guidelines-industrial-security.pdf>) and following the recommendations in the product manuals.\n\nFor additional information see Siemens Security Advisory [SSA-723417](<https://cert-portal.siemens.com/productcert/pdf/ssa-723417.pdf>)\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\nCISA also 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](<https://us-cert.cisa.gov/sites/default/files/publications/emailscams_0905.pdf>) for more information on avoiding email scams.\n * Refer to [Avoiding Social Engineering and Phishing Attacks](<https://us-cert.cisa.gov/ncas/tips/ST04-014>) for more information on social engineering attacks.\n\nNo known public exploits specifically target these vulnerabilities.\n\n### Vendor\n\nSiemens\n", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2021-10-14T12:00:00", "type": "ics", "title": "Siemens SCALANCE W1750D (Update B)", "bulletinFamily": "info", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2019-5317", "CVE-2019-5319", "CVE-2020-24635", "CVE-2020-24636", "CVE-2021-25143", "CVE-2021-25144", "CVE-2021-25145", "CVE-2021-25146", "CVE-2021-25148", "CVE-2021-25149", "CVE-2021-25150", "CVE-2021-25155", "CVE-2021-25156", "CVE-2021-25157", "CVE-2021-25158", "CVE-2021-25159", "CVE-2021-25160", "CVE-2021-25161", "CVE-2021-25162", "CVE-2021-34617", "CVE-2021-34618"], "modified": "2021-10-14T12:00:00", "id": "ICSA-21-131-14", "href": "https://www.cisa.gov/news-events/ics-advisories/icsa-21-131-14", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}], "nessus": [{"lastseen": "2023-05-17T16:44:58", "description": "A remote arbitrary file read vulnerability was discovered in some Aruba Instant Access Point (IAP) products in version(s): Aruba Instant 6.5.x: 6.5.4.18 and below; Aruba Instant 8.3.x: 8.3.0.14 and below;\nAruba Instant 8.5.x: 8.5.0.11 and below; Aruba Instant 8.6.x: 8.6.0.7 and below; Aruba Instant 8.7.x: 8.7.1.1 and below.
