1. EXECUTIVE SUMMARY
o CVSS v3 5.2
o ATTENTION: Exploitable remotely/low attack complexity
o Vendor: Eaton
o Equipment: Intelligent Power Manager (IPM) v1
o Vulnerability: Cross-site Scripting
2. RISK EVALUATION
Successful exploitation of this vulnerability could allow an attacker to
execute arbitrary code using untrusted data.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of Eaton IPM, a power management platform, are affected:
o Eaton Intelligent Power Manager (IPM) v1: All versions prior to v1.70
3.2 VULNERABILITY OVERVIEW
3.2.1 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION ('CROSS-SITE
SCRIPTING') CWE-79
The affected product is vulnerable to a reflected cross-site scripting
vulnerability due to insufficient validation of input from certain resources by
the IPM software. An attacker would need access to the local subnet and an
administrator interaction to compromise the system.
CVE-2021-23282 has been assigned to this vulnerability. A CVSS v3 base score of
5.2 has been calculated; the CVSS vector string is ( AV:A/AC:L/PR:H/UI:N/S:U/
C:N/I:L/A:H ).
3.3 BACKGROUND
o CRITICAL INFRASTRUCTURE SECTORS: Multiple Sectors
o COUNTRIES/AREAS DEPLOYED: Worldwide
o COMPANY HEADQUARTERS LOCATION: Ireland
3.4 RESEARCHER
Michael Heinzl reported this vulnerability to CISA.
4. MITIGATIONS
Eaton recommends users upgrade to the latest version of Intelligent Power
Manager:
o Eaton IPM: Update to v1.70
Eaton recommends users follow the security best practices and configure the
logical access mechanisms provided in IPM to safeguard the application from
unauthorized access. IPM provides various types of administrative, operational,
and configuration privilege levels. Use the available access control mechanisms
properly to ensure system and application access is restricted to legitimate
users only. Ensure users are restricted to only the privilege levels necessary
to complete their job roles/functions.
o Restrict exposure to external networks for all control system devices and/
or systems and ensure they are not directly accessible from the open
Internet.
o Deploy control system networks and remote devices behind barrier devices
(e.g., firewalls, data diodes) and isolate them from business networks.
o Remote access to control system networks should be made available on a
strict need-to-use basis. Remote access should use secure methods, such as
virtual private networks (VPNs), updated to the most current version
available.
o Regularly update software and applications to the latest versions
available, as applicable.
o Enable audit logs on all devices and applications.
o Disable/deactivate unused communication channels, TCP/UDP ports and
services (e.g., SNMP, FTP, BootP, DHCP, etc.) on networked devices.
o Create security zones for devices with common security requirements using
barrier devices (e.g., firewalls, data diodes).
o Change default passwords following initial startup. Use complex secure
passwords or passphrases.
o Perform regular security assessments and risk analysis of networked control
systems.
