1. EXECUTIVE SUMMARY

  o CVSS v3 5.7
  o ATTENTION: Exploitable remotely/low attack complexity
  o Vendor: Eaton
  o Equipment: Intelligent Power Manager Infrastructure
  o Vulnerabilities: Cross-site Scripting, Reflected Cross-site Scripting,
    Improper Neutralization of Formula in a CSV File

2. RISK EVALUATION

Successful exploitation of these vulnerabilities could allow an attacker to
execute arbitrary code using untrusted data.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following Eaton Intelligent power monitoring products are affected:

  o Eaton Intelligent Power Manager Infrastructure (IPM Infrastructure): All
    versions including v1.5.0 plus205

3.2 VULNERABILITY OVERVIEW

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

The affected product has reached its End of Life, it is vulnerable to a stored
cross-site scripting vulnerability due to insufficient validation of input from
certain resources by the IPM Infrastructure software. The attacker would need
access to the local Subnet and an administrator interaction to compromise the
system.

CVE-2021-23284 has been assigned to this vulnerability. A CVSS v3 base score of
5.7 has been calculated; the CVSS vector string is ( AV:A/AC:L/PR:H/UI:N/S:U/
C:L/I:L/A:H ).

3.2.2 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION ('CROSS-SITE
SCRIPTING') CWE-79

The affected product has reached its End of Life, it is vulnerable to a
reflected cross-site scripting vulnerability due to insufficient validation of
input from certain resources by the IPM Infrastructure software. The attacker
would need access to the local Subnet and an administrator interaction to
compromise the system.

CVE-2021-23285 has been assigned to this vulnerability. A CVSS v3 base score of
3.1 has been calculated; the CVSS vector string is ( AV:A/AC:H/PR:H/UI:N/S:U/
C:L/I:L/A:N ).

3.2.3 IMPROPER NEUTRALIZATION OF FORMULA ELEMENTS IN A CSV FILE CWE-1236

The affected product has reached its End of Life, it is vulnerable to a CSV
Formula Injection. The vulnerability exists due to improper sanitization of
imported CSV files. The attacker would need access to the local Subnet and an
administrator interaction to compromise the system.

CVE-2021-23286 has been assigned to this vulnerability. A CVSS v3 base score of
5.4 has been calculated; the CVSS vector string is ( AV:A/AC:L/PR:H/UI:R/S:U/
C:L/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 these vulnerabilities to CISA.

4. MITIGATIONS

The product has reached its End Of Life, the notification has been posted at:
Lifecycle Notification . The transition to IPM Monitor Edition is in progress.
Refer the Product page for further details.

Until the transition is complete, Eaton recommends the below guidelines should
be followed.

  o To prevent the exploitation of the issues and safeguard the software from
    malicious entities, ensure access to the system is provided to the known
    users and the credentials are secured.

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,
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 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.

For additional information, please visit Eaton's cybersecurity website .

CISA recommends users take defensive measures to minimize the risk of
exploitation of these vulnerabilities. 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 on cisa.gov 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 webpage on cisa.gov 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 CISA for tracking
and correlation against other incidents.

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

  o Do not click web links or open unsolicited attachments in email messages.
  o Refer to Recognizing and Avoiding Email Scams for more information on
    avoiding email scams.
  o Refer to Avoiding Social Engineering and Phishing Attacks for more
    information on social engineering attacks.

No known public exploits specifically target these vulnerabilities.
