CVSS v3 9.8

ATTENTION: Remotely exploitable/low skill level to exploit.

Vendor: Schneider Electric

Equipment: Wonderware Intelligence

Vulnerability: Credentials Management


The following versions of Wonderware Intelligence, an operations management 
software, are affected:

Tableau Server/Desktop Versions 7.0 to 10.1.3 included in Wonderware 
Intelligence Versions 2014R3 and prior.


The vulnerability, if exploited, could allow a malicious entity to escalate 
its privilege to an administrator and take control over the host machine where
Tableau Server is installed.


Schneider Electric has released a new software version to address the 
identified vulnerability and recommends that users using affected versions 
apply Tableau Server Version 10.1.4. In addition, the Analytics Client 
(Tableau Desktop OEM) should also be upgraded to Version 10.1.4. Upgrading to
Intelligence Server 2014 R3 is also recommended.

The Schneider Electric customers using Wonderware Intelligence can login at 
the following support sites to download the Tableau patches:

NCCIC/ICS-CERT recommends that users take defensive measures to minimize the 
risk of exploitation of this vulnerability. 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 ICSCERT 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.

No known public exploits specifically target this vulnerability.



Tableau Server is embedded within the Schneider Electric Wonderware 
Intelligence software and contains a system account that is installed by 
default. The default system account is difficult to modify to use non-default
credentials after installation and changing the default credentials in the 
embedded Tableau Server is not documented. As such, Schneider Electric has 
released a new software version that removes the default system account in the
embedded Tableau Server.

If Tableau Server is used with Windows integrated security (Active Directory),
the software is not vulnerable. However, when Tableau Server is used with 
local authentication mode, the software is vulnerable. The default system 
account could be used to gain unauthorized access.

CVE-2017-5178 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is 


Schneider Electric self-reported this vulnerability.
