The software does not validate the filenames sufficiently, which enables
authenticated administrator-level users to perform path traversal attacks and
specify arbitrary files.
CVE-2022-2106 has been assigned to this vulnerability. A CVSS v3 base score of
3.8 has been calculated; the CVSS vector string is ( AV:N/AC:L/PR:H/UI:N/S:U/

4. MITIGATIONS
Elcomplus has released Version 2.4 to address these vulnerabilities and
recommends users update to the newest version. Users can obtain the new version
from Elcomplus .
CISA recommends users take defensive measures to minimize the risk of
exploitation of these vulnerabilities. Specifically, users should:
o Minimize network exposure for all control system devices and/or systems,
and ensure 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 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 on cisa.gov/ics 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/ics in the Technical Information Paper,
