ATTENTION: Remotely exploitable/low skill level to exploit.
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:
Successful exploitation of these vulnerabilities could allow an unauthorized user to create an account on the device or access the device’s 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 vulnerabilities.
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:
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.
No known public exploits specifically target these vulnerabilities.
An attacker may create an application user account to gain administrative privileges.
The application is vulnerable to injection of malicious SQL queries via the input from the client.
Semen Rozhkov of Kaspersky Lab discovered these vulnerabilities. OPW hired a third party testing firm to validate that the firmware upgrade resolved the security issues.
