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.
