Always verify the source of the file before opening it.</p> <p><strong>Mitigation</strong><br />Avoid running as administrator: Do not use the "Run as Administrator" option when launching the software. Running the software with standard user privileges effectively limits the damage of potential malicious code.</p> <p><strong>Mitigation</strong><br />For more information refer to Delta Electronic's advisory page <a href="https://www.deltaww.com/en-US/service-support/product-cybersecurity/advisory">https://www.deltaww.com/en-US/service-support/product-cybersecurity/advisory</a></p> </div> <p><strong>Relevant CWE:</strong> <a href="https://cwe.mitre.org/data/definitions/502.html">CWE-502 Deserialization of Untrusted Data</a></p> <hr /> <h4>Metrics</h4> <div class="csaf-table csaf-metrics-table"> <table class="tablesaw tablesaw-stack"> <thead> <tr> <th>CVSS Version</th> <th>Base Score</th> <th>Base Severity</th> <th>Vector String</th> </tr> </thead> <tbody> <tr> <td>3.1</td> <td>7.8</td> <td>HIGH</td> <td><a href="https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H">CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H</a></td> </tr> <tr> <td>4.0</td> <td>8.4</td> <td>HIGH</td> <td><a href="https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N">CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N</a></td> </tr> </tbody> </table> </div> </div> </div> </div> <hr /> <h2>Acknowledgments</h2> <ul> <li>kimiya of TrendAI Zero Day Initiative reported this vulnerability to CISA</li> </ul> <hr /> <h2>Legal Notice and Terms of Use</h2> <p>This product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy).</p> <hr /> <h2>Recommended Practices</h2> <p>CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability.</p> <p>Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.</p> <p>Locate control system networks and remote devices behind firewalls and isolating them from business networks.</p> <p>When remote access is required, use more 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 the connected devices.</p> <p>CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.</p> <p>CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.</p> <p>CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.</p> <p>Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.</p> <p>Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.</p> <p>CISA also recommends users take the following measures to protect themselves from social engineering attacks:</p> <p>Do not click web links or open attachments in unsolicited email messages.</p> <p>Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.</p> <p>Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.</p> <p>No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time.
