EXECUTIVE SUMMARY o CVSS v3 9.8 o ATTENTION: Exploitable remotely/low skill level to exploit/public exploits are available o Vendor: Rockwell Automation o Equipment: Allen-Bradley PowerMonitor 1000 o Vulnerabilities: Cross-site Scripting and Authentication Bypass 2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow a remote attacker to affect the confidentiality, integrity, and availability of the device. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of PowerMonitor 1000, a monitoring platform, are affected: o PowerMonitor 1000, all versions. 3.2 VULNERABILITY OVERVIEW 3.2.1 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION ('CROSS-SITE SCRIPTING') CWE-79 A remote attacker could inject arbitrary code into a targeted user's web browser to gain access to the affected device. CVE-2019-19615 has been assigned to this vulnerability. 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). 3.2.2 AUTHENTICATION BYPASS USING AN ALTERNATE PATH OR CHANNEL CWE-288 A remote attacker may be able to use a proxy to enable functionality that is typically available to those with administrative rights for the web application, allowing the attacker to bypass authentication. Once bypassed, the attacker could disrupt user settings and device configuration. CVE-2019-19616 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). 3.3 BACKGROUND o CRITICAL INFRASTRUCTURE SECTORS: Energy o COUNTRIES/AREAS DEPLOYED: Worldwide o COMPANY HEADQUARTERS LOCATION: United States 3.4 RESEARCHER Luca Chiou of ACSI reported these vulnerabilities to NCCIC. 4. MITIGATIONS Rockwell Automation is currently working on mitigations and reports that CheckPoint Software Technologies has released IPS rules to detect attempts to exploit CVE-2019-19615. For more information, Rockwell Automation has released a security notification that can be found at (login required): https://rockwellautomation.custhelp.com/ app/answers/detail/a_id/1084790 NCCIC recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should: o Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet. o Locate control system networks and remote devices behind firewalls, and isolate them from the business network. o 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. NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. NCCIC 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. Additional 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. Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.
