Vendor: OPW Fuel Management Systems

Equipment: SiteSentinel Integra and SiteSentinel iSite

Vulnerabilities: Missing Authentication for Critical Function, SQL Injection


OPW Fuel Management Systems (OPW) reports that the vulnerabilities affect 
SiteSentinel Integra 100, SiteSentinel Integra 500, and SiteSentinel iSite ATG
consoles with the following software versions:

Older than V175,


V191-V195, and



Successful exploitation of these vulnerabilities could allow an unauthorized 
user to create an account on the device or access the devices database.


OPW considers this a critical issue that needs to be addressed immediately. 
They have issued Service Bulletin 462 and a letter to users to inform them of
the availability of free upgrades (firmware Version 17Q2.1) to mitigate these

OPW recommends that users upgrade all affected systems even if they are 
already protected from exploitation by running off-line or located on a 
protected network.

OPW has released instructions telling users how to update to the newest 
firmware version. For specific step-by-step instructions on how to save 
settings, backup database, and install the new firmware, see the upgrade 
procedure (M00-20-4438) at the following location:

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 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 these vulnerabilities.
