CVSS v3 6.8
ATTENTION: Remotely exploitable/low skill level to exploit.
Vendor: Progea
Equipment: Movicon SCADA/HMI
Vulnerability: Uncontrolled Search Path Element, Unquoted Search Path or
Element
AFFECTED PRODUCTS
The following versions of Movicon HMI, an HMI software platform, are affected:
Movicon Version 11.5.1181 and prior.
IMPACT
Successful exploitation of these vulnerabilities could allow privilege
escalation or arbitrary code execution.
MITIGATION
Progea has not provided an update to address these vulnerabilities. However,
Progea has issued a knowledge base article about DLL Hijacking, which can be
found at the following location:
http://www.movicon.info/Support/MoviconKB/WebHelp/Knowledgebase/kb000035.htm
(link is external)
NCCIC/ICS-CERT recommends that users take defensive measures to minimize the
risk of exploitation of these vulnerabilities. Specifically, users should:
Minimize network exposure for all control system devices and/or systems, and
ensure that they are not accessible from the Internet.
Locate control system networks and remote devices behind firewalls, and
isolate them from the business network.
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.
ICS-CERT reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
ICS-CERT 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 in the ICS-CERT Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies, that is available for download from the ICS-CERT web site.
Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to ICS-CERT for
tracking and correlation against other incidents.
In addition, ICS-CERT recommends that users take the following measures to
protect themselves from social engineering attacks which could lead a user to
download a malicious DLL file accidentally:
1.Do not click web links or open unsolicited attachments in email messages.
2.Refer to Recognizing and Avoiding Email Scams for more information on
avoiding email scams.
3.Refer to Avoiding Social Engineering and Phishing Attacks for more
information on social engineering attacks.
No known public exploits specifically target these vulnerabilities.
