![]() Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.Īdditional mitigation guidance and recommended practices are publicly available on the ICS webpage on in the Technical Information Paper, ICS-TIP-12-146-01B-Targeted Cyber Intrusion Detection and Mitigation Strategies. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.ĬISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.ĬISA also provides a section for control systems security recommended practices on the ICS webpage on.Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.To operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens operational guidelines for Industrial Security and following the recommendations in the product manuals.įor additional information, please refer to Siemens Security Advisory SSA-436520ĬISA also recommends users take the following measures to protect themselves from social engineering attacks: ![]() Do not open unknown links while working on Polarion Subversion Webclient.Īs a general security measure, Siemens strongly recommends protecting network access to devices with appropriate mechanisms.Siemens has identified the following specific workaround and mitigation users can apply to reduce the risk: Siemens has stated that the tool is considered shareware, distributed “as is,” and will be no fix as it is no longer supported. Li Yifan reported these vulnerabilities to Siemens. CRITICAL INFRASTRUCTURE SECTORS: Energy.A CVSS v3 base score of 8.1 has been calculated the CVSS vector string is ( AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N). This could allow the attacker to read or modify contents of the web application.ĬVE-2020-15789 has been assigned to this vulnerability. A successful attack could allow an attacker to trigger actions via the web interface that the legitimate user is allowed to perform. Successful exploitation requires user interaction by a legitimate user, who must be authenticated to the web interface. The web interface could allow a CSRF attack if an unsuspecting user is tricked into accessing a malicious link. 3.2.2 CROSS-SITE REQUEST FORGERY (CSRF) CWE-352 A CVSS v3 base score of 6.1 has been calculated the CVSS vector string is ( AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N). ![]() Various actions could be triggered by running malicious JavaScript code.ĬVE-2020-15788 has been assigned to this vulnerability. If a user is enticed into passing specially crafted malicious input to the web client (e.g., by clicking on a malicious URL with embedded JavaScript), JavaScript code can be returned and executed by the user’s client. The Polarion Subversion Webclient application does not filter user input in a way that prevents cross-site scripting (XSS).
