1. EXECUTIVE SUMMARY

CVSS v3 8.8
ATTENTION: Exploitable remotely/low attack complexity
Vendor: Rockwell Automation
Equipment: PowerMonitor 1000
Vulnerability: Cross-site Scripting

2. RISK EVALUATION

Successful exploitation of this vulnerability could allow an attacker to achieve remote code execution and potentially the complete loss of confidentiality, integrity, and availability of the product.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following versions of Rockwell Automation PowerMonitor 1000 are affected: 

PowerMonitor 1000: V4.011

3.2 VULNERABILITY OVERVIEW

3.2.1 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION (‘CROSS-SITE SCRIPTING’) CWE-79

The PowerMonitor 1000 contains stored cross site scripting vulnerabilities within the web page of the product. The vulnerable pages do not require privileges to access and can be injected with code by an attacker which could be used to leverage an attacker on an authenticated user resulting in remote code execution and potentially the complete loss of confidentiality, integrity, and availability of the product.

CVE-2023-2072 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

3.3 BACKGROUND

CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing
COUNTRIES/AREAS DEPLOYED: Worldwide
COMPANY HEADQUARTERS LOCATION: United States

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:

Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.
Locate control system networks and remote devices behind firewalls and isolate them from business networks.
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.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage at 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.

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.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

CISA also recommends users take the following measures to protect themselves from social engineering attacks:

Do not click web links or open attachments in unsolicited email messages.
